NAME

       cmake-modules - CMake Modules Reference

ALL MODULES

   AddFileDependencies
       ADD_FILE_DEPENDENCIES(source_file depend_files...)

       Adds the given files as dependencies to source_file

   BundleUtilities
       Functions to help assemble a standalone bundle application.

       A  collection  of  CMake utility functions useful for dealing with .app bundles on the Mac
       and bundle-like directories on any OS.

       The following functions are provided by this module:

          fixup_bundle
          copy_and_fixup_bundle
          verify_app
          get_bundle_main_executable
          get_dotapp_dir
          get_bundle_and_executable
          get_bundle_all_executables
          get_item_key
          get_item_rpaths
          clear_bundle_keys
          set_bundle_key_values
          get_bundle_keys
          copy_resolved_item_into_bundle
          copy_resolved_framework_into_bundle
          fixup_bundle_item
          verify_bundle_prerequisites
          verify_bundle_symlinks

       Requires CMake 2.6 or greater because it uses  function,  break  and  PARENT_SCOPE.   Also
       depends on GetPrerequisites.cmake.

          FIXUP_BUNDLE(<app> <libs> <dirs>)

       Fix up a bundle in-place and make it standalone, such that it can be drag-n-drop copied to
       another machine and run on that machine as  long  as  all  of  the  system  libraries  are
       compatible.

       If you pass plugins to fixup_bundle as the libs parameter, you should install them or copy
       them into the bundle before calling fixup_bundle.  The  "libs"  parameter  is  a  list  of
       libraries  that  must be fixed up, but that cannot be determined by otool output analysis.
       (i.e., plugins)

       Gather all the keys for all the executables and libraries in a bundle, and then, for  each
       key,  copy  each  prerequisite into the bundle.  Then fix each one up according to its own
       list of prerequisites.

       Then clear all the keys and call verify_app on the final bundle to ensure that it is truly
       standalone.

          COPY_AND_FIXUP_BUNDLE(<src> <dst> <libs> <dirs>)

       Makes a copy of the bundle <src> at location <dst> and then fixes up the new copied bundle
       in-place at <dst>...

          VERIFY_APP(<app>)

       Verifies that an application <app> appears valid based on running analysis  tools  on  it.
       Calls "message(FATAL_ERROR" if the application is not verified.

          GET_BUNDLE_MAIN_EXECUTABLE(<bundle> <result_var>)

       The  result will be the full path name of the bundle's main executable file or an "error:"
       prefixed string if it could not be determined.

          GET_DOTAPP_DIR(<exe> <dotapp_dir_var>)

       Returns the nearest parent dir whose name ends with ".app"  given  the  full  path  to  an
       executable.   If  there  is  no such parent dir, then simply return the dir containing the
       executable.

       The returned directory may or may not exist.

          GET_BUNDLE_AND_EXECUTABLE(<app> <bundle_var> <executable_var> <valid_var>)

       Takes either a ".app" directory name or the name of an executable nested inside  a  ".app"
       directory and returns the path to the ".app" directory in <bundle_var> and the path to its
       main executable in <executable_var>

          GET_BUNDLE_ALL_EXECUTABLES(<bundle> <exes_var>)

       Scans the given bundle recursively for all executable files and accumulates  them  into  a
       variable.

          GET_ITEM_KEY(<item> <key_var>)

       Given  a  file  (item)  name,  generate a key that should be unique considering the set of
       libraries that need copying or fixing up to make a bundle standalone.  This is essentially
       the file name including extension with "." replaced by "_"

       This  key  is  used  as  a  prefix  for  CMake variables so that we can associate a set of
       variables with a given item based on its key.

          CLEAR_BUNDLE_KEYS(<keys_var>)

       Loop over the list of keys, clearing all the variables associated with  each  key.   After
       the loop, clear the list of keys itself.

       Caller of get_bundle_keys should call clear_bundle_keys when done with list of keys.

          SET_BUNDLE_KEY_VALUES(<keys_var> <context> <item> <exepath> <dirs>
                                <copyflag> [<rpaths>])

       Add  a  key  to  the  list  (if necessary) for the given item.  If added, also set all the
       variables associated with that key.

          GET_BUNDLE_KEYS(<app> <libs> <dirs> <keys_var>)

       Loop over all the executable and library files within  the  bundle  (and  given  as  extra
       <libs>)  and accumulate a list of keys representing them.  Set values associated with each
       key such that we can loop over all of them and copy prerequisite libs into the bundle  and
       then do appropriate install_name_tool fixups.

          COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

       Copy  a  resolved  item  into  the  bundle  if  necessary.   Copy  is not necessary if the
       resolved_item is "the same as" the resolved_embedded_item.

          COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

       Copy a resolved framework into the bundle if necessary.  Copy  is  not  necessary  if  the
       resolved_item is "the same as" the resolved_embedded_item.

       By  default,  BU_COPY_FULL_FRAMEWORK_CONTENTS  is  not  set.   If you want full frameworks
       embedded in  your  bundles,  set  BU_COPY_FULL_FRAMEWORK_CONTENTS  to  ON  before  calling
       fixup_bundle.   By default, COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies the framework dylib
       itself plus the framework Resources directory.

          FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>)

       Get  the  direct/non-system  prerequisites  of  the  resolved  embedded  item.   For  each
       prerequisite,  change  the  way  it is referenced to the value of the _EMBEDDED_ITEM keyed
       variable for that prerequisite.  (Most likely  changing  to  an  "@executable_path"  style
       reference.)

       This function requires that the resolved_embedded_item be "inside" the bundle already.  In
       other words, if you pass plugins to fixup_bundle as the libs parameter, you should install
       them  or copy them into the bundle before calling fixup_bundle.  The "libs" parameter is a
       list of libraries that must be fixed up, but that cannot be  determined  by  otool  output
       analysis.  (i.e., plugins)

       Also, change the id of the item being fixed up to its own _EMBEDDED_ITEM value.

       Accumulate  changes  in a local variable and make one call to install_name_tool at the end
       of the function with all the changes at once.

       If the BU_CHMOD_BUNDLE_ITEMS variable is set then bundle items  will  be  marked  writable
       before install_name_tool tries to change them.

          VERIFY_BUNDLE_PREREQUISITES(<bundle> <result_var> <info_var>)

       Verifies  that  the  sum of all prerequisites of all files inside the bundle are contained
       within the bundle or are "system" libraries, presumed to exist everywhere.

          VERIFY_BUNDLE_SYMLINKS(<bundle> <result_var> <info_var>)

       Verifies that any symlinks found in the bundle point to other files that are already  also
       in  the  bundle...   Anything that points to an external file causes this function to fail
       the verification.

   CheckCCompilerFlag
       Check whether the C compiler supports a given flag.

       CHECK_C_COMPILER_FLAG(<flag> <var>)

          <flag> - the compiler flag
          <var>  - variable to store the result
                   Will be created as an internal cache variable.

       This    internally    calls     the     check_c_source_compiles     macro     and     sets
       CMAKE_REQUIRED_DEFINITIONS  to <flag>.  See help for CheckCSourceCompiles for a listing of
       variables that can otherwise modify the build.  The result only tells  that  the  compiler
       does not give an error message when it encounters the flag.  If the flag has any effect or
       even a specific one is beyond the scope of this module.

   CheckCSourceCompiles
       Check if given C source compiles and links into an executable

       CHECK_C_SOURCE_COMPILES(<code> <var> [FAIL_REGEX <fail-regex>])

          <code>       - source code to try to compile, must define 'main'
          <var>        - variable to store whether the source code compiled
                         Will be created as an internal cache variable.
          <fail-regex> - fail if test output matches this regex

       The following variables may be set before calling this macro to modify the way  the  check
       is run:

          CMAKE_REQUIRED_FLAGS = string of compile command line flags
          CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
          CMAKE_REQUIRED_INCLUDES = list of include directories
          CMAKE_REQUIRED_LIBRARIES = list of libraries to link
          CMAKE_REQUIRED_QUIET = execute quietly without messages

   CheckCSourceRuns
       Check if the given C source code compiles and runs.

       CHECK_C_SOURCE_RUNS(<code> <var>)

          <code>   - source code to try to compile
          <var>    - variable to store the result
                     (1 for success, empty for failure)
                     Will be created as an internal cache variable.

       The  following  variables may be set before calling this macro to modify the way the check
       is run:

          CMAKE_REQUIRED_QUIET = execute quietly without messages

   CheckCXXCompilerFlag
       Check whether the CXX compiler supports a given flag.

       CHECK_CXX_COMPILER_FLAG(<flag> <var>)

          <flag> - the compiler flag
          <var>  - variable to store the result

       This    internally    calls    the    check_cxx_source_compiles     macro     and     sets
       CMAKE_REQUIRED_DEFINITIONS  to  <flag>.  See help for CheckCXXSourceCompiles for a listing
       of variables that can otherwise modify the build.  The result only tells that the compiler
       does not give an error message when it encounters the flag.  If the flag has any effect or
       even a specific one is beyond the scope of this module.

   CheckCXXSourceCompiles
       Check if given C++ source compiles and links into an executable

       CHECK_CXX_SOURCE_COMPILES(<code> <var> [FAIL_REGEX <fail-regex>])

          <code>       - source code to try to compile, must define 'main'
          <var>        - variable to store whether the source code compiled
                         Will be created as an internal cache variable.
          <fail-regex> - fail if test output matches this regex

       The following variables may be set before calling this macro to modify the way  the  check
       is run:

          CMAKE_REQUIRED_FLAGS = string of compile command line flags
          CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
          CMAKE_REQUIRED_INCLUDES = list of include directories
          CMAKE_REQUIRED_LIBRARIES = list of libraries to link
          CMAKE_REQUIRED_QUIET = execute quietly without messages

   CheckCXXSourceRuns
       Check if the given C++ source code compiles and runs.

       CHECK_CXX_SOURCE_RUNS(<code> <var>)

          <code>   - source code to try to compile
          <var>    - variable to store the result
                     (1 for success, empty for failure)
                     Will be created as an internal cache variable.

       The  following  variables may be set before calling this macro to modify the way the check
       is run:

          CMAKE_REQUIRED_FLAGS = string of compile command line flags
          CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
          CMAKE_REQUIRED_INCLUDES = list of include directories
          CMAKE_REQUIRED_LIBRARIES = list of libraries to link
          CMAKE_REQUIRED_QUIET = execute quietly without messages

   CheckCXXSymbolExists
       Check if a symbol exists as a function, variable, or macro in C++

       CHECK_CXX_SYMBOL_EXISTS(<symbol> <files> <variable>)

       Check that the <symbol> is available after including given header <files>  and  store  the
       result   in   a   <variable>.    Specify   the   list  of  files  in  one  argument  as  a
       semicolon-separated list.  CHECK_CXX_SYMBOL_EXISTS() can be used to check in C++ files, as
       opposed to CHECK_SYMBOL_EXISTS(), which works only for C.

       If the header files define the symbol as a macro it is considered available and assumed to
       work.  If the header files declare the symbol as a function or variable  then  the  symbol
       must  also be available for linking.  If the symbol is a type or enum value it will not be
       recognized (consider using CheckTypeSize or CheckCSourceCompiles).

       The following variables may be set before calling this macro to modify the way  the  check
       is run:

          CMAKE_REQUIRED_FLAGS = string of compile command line flags
          CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
          CMAKE_REQUIRED_INCLUDES = list of include directories
          CMAKE_REQUIRED_LIBRARIES = list of libraries to link
          CMAKE_REQUIRED_QUIET = execute quietly without messages

   CheckFortranCompilerFlag
       Check whether the Fortran compiler supports a given flag.

       CHECK_Fortran_COMPILER_FLAG(<flag> <var>)

          <flag> - the compiler flag
          <var>  - variable to store the result
                   Will be created as an internal cache variable.

       This    internally    calls    the    check_fortran_source_compiles    macro    and   sets
       CMAKE_REQUIRED_DEFINITIONS to <flag>.   See  help  for  CheckFortranSourceCompiles  for  a
       listing  of variables that can otherwise modify the build.  The result only tells that the
       compiler does not give an error message when it encounters the flag.  If the flag has  any
       effect or even a specific one is beyond the scope of this module.

   CheckFortranFunctionExists
       macro which checks if the Fortran function exists

       CHECK_FORTRAN_FUNCTION_EXISTS(FUNCTION VARIABLE)

          FUNCTION - the name of the Fortran function
          VARIABLE - variable to store the result
                     Will be created as an internal cache variable.

       The  following  variables may be set before calling this macro to modify the way the check
       is run:

          CHECK_Fortran_SOURCE_COMPILES(<code> <var> [FAIL_REGEX <fail-regex>])

       The arguments are:

       <code> Source code to try to compile.  It must define a PROGRAM entry point.

       <var>  Variable to store whether the source code compiled.  Will be created as an internal
              cache variable.

       <fail-regex>
              Fail if test output matches this regex.

       The  following  variables may be set before calling this macro to modify the way the check
       is run:

          CMAKE_REQUIRED_FLAGS = string of compile command line flags
          CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
          CMAKE_REQUIRED_INCLUDES = list of include directories
          CMAKE_REQUIRED_LIBRARIES = list of libraries to link
          CMAKE_REQUIRED_QUIET = execute quietly without messages

   CheckFunctionExists
       Check if a C function can be linked

       CHECK_FUNCTION_EXISTS(<function> <variable>)

       Check that the <function> is provided by libraries on the system and store the result in a
       <variable>.   This does not verify that any system header file declares the function, only
       that it can be found at link time (consider using CheckSymbolExists).  <variable> will  be
       created as an internal cache variable.

       The  following  variables may be set before calling this macro to modify the way the check
       is run:

          CMAKE_REQUIRED_FLAGS = string of compile command line flags

       CHECK_INCLUDE_FILE_CXX

                 CHECK_INCLUDE_FILE_CXX(<include> <variable> [<flags>])

              Check if the given <include> file may be included in a CXX source  file  and  store
              the  result  in  an  internal  cache  entry  named  <variable>.  The optional third
              argument  may  be  used  to  add  compilation  flags   to   the   check   (or   use
              CMAKE_REQUIRED_FLAGS below).

              list of include directories

       CMAKE_REQUIRED_QUIET
              execute quietly without messages

       See modules CheckIncludeFile and CheckIncludeFiles to check for one or more C headers.

   CheckIncludeFile
       Provides a macro to check if a header file can be included in C.

       CHECK_INCLUDE_FILE

                 CHECK_INCLUDE_FILE(<include> <variable> [<flags>])

              Check if the given <include> file may be included in a C source file and store  the
              result  in  an  internal cache entry named <variable>.  The optional third argument
              may be used to add compilation flags to  the  check  (or  use  CMAKE_REQUIRED_FLAGS
              below).

       The  following  variables may be set before calling this macro to modify the way the check
       is run:

       CMAKE_REQUIRED_FLAGS
              string of compile command line flags

       CMAKE_REQUIRED_DEFINITIONS
              list of macros to define (-DFOO=bar)

       CMAKE_REQUIRED_INCLUDES
              list of include directories

       CMAKE_REQUIRED_QUIET
              execute quietly without messages

       See the CheckIncludeFiles  module  to  check  for  multiple  headers  at  once.   See  the
       CheckIncludeFileCXX module to check for headers using the CXX language.

   CheckIncludeFiles
       Provides  a  macro to check if a list of one or more header files can be included together
       in C.

              <includes> argument as a ;-list of header file names.

       The following variables may be set before calling this macro to modify the way  the  check
       is run:

       CMAKE_REQUIRED_FLAGS
              string of compile command line flags

       CMAKE_REQUIRED_DEFINITIONS

              list of include directories

       CMAKE_REQUIRED_QUIET
              execute quietly without messages

       See  modules CheckIncludeFile and CheckIncludeFileCXX to check for a single header file in

   CheckLanguage
       Check if a language can be enabled

       Usage:

          check_language(<lang>)

       where <lang> is a language that may be passed to enable_language() such as "Fortran".   If
       CMAKE_<lang>_COMPILER  is  already  defined  the  check  does nothing.  Otherwise it tries
       enabling the language in a test project.  The result is cached in CMAKE_<lang>_COMPILER as
       the compiler that was found, or NOTFOUND if the language cannot be enabled.

       Example:

          check_language(Fortran)
          if(CMAKE_Fortran_COMPILER)
            enable_language(Fortran)
          else()
            message(STATUS "No Fortran support")
          endif()

   CheckLibraryExists
       Check if the function exists.

       CHECK_LIBRARY_EXISTS (LIBRARY FUNCTION LOCATION VARIABLE)

          LIBRARY  - the name of the library you are looking for
          FUNCTION - the name of the function
          LOCATION - location where the library should be found
          VARIABLE - variable to store the result
                     Will be created as an internal cache variable.

       The  following  variables may be set before calling this macro to modify the way the check
       is run:

          CMAKE_REQUIRED_FLAGS = string of compile command line flags
          CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
          CMAKE_REQUIRED_LIBRARIES = list of libraries to link
          CMAKE_REQUIRED_QUIET = execute quietly without messages

   CheckPrototypeDefinition
       Check if the protoype we expect is correct.

       check_prototype_definition(FUNCTION PROTOTYPE RETURN HEADER VARIABLE)

          FUNCTION - The name of the function (used to check if prototype exists)
          PROTOTYPE- The prototype to check.
          RETURN - The return value of the function.
          HEADER - The header files required.
          VARIABLE - The variable to store the result.
                     Will be created as an internal cache variable.

       Example:

          check_prototype_definition(getpwent_r
           "struct passwd *getpwent_r(struct passwd *src, char *buf, int buflen)"
           "NULL"
           "unistd.h;pwd.h"
           SOLARIS_GETPWENT_R)

       The following variables may be set before calling this macro to modify the way  the  check
       is run:

          CMAKE_REQUIRED_FLAGS = string of compile command line flags
          CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
          CMAKE_REQUIRED_INCLUDES = list of include directories
          CMAKE_REQUIRED_LIBRARIES = list of libraries to link
          CMAKE_REQUIRED_QUIET = execute quietly without messages

   CheckStructHasMember
       Check if the given struct or class has the specified member variable

          CHECK_STRUCT_HAS_MEMBER(<struct> <member> <header> <variable>
                                  [LANGUAGE <language>])

          <struct> - the name of the struct or class you are interested in
          <member> - the member which existence you want to check
          <header> - the header(s) where the prototype should be declared
          <variable> - variable to store the result
          <language> - the compiler to use (C or CXX)

       The  following  variables may be set before calling this macro to modify the way the check
       is run:

          CMAKE_REQUIRED_FLAGS = string of compile command line flags
          CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
          CMAKE_REQUIRED_INCLUDES = list of include directories
          CMAKE_REQUIRED_LIBRARIES = list of libraries to link
          CMAKE_REQUIRED_QUIET = execute quietly without messages

       Example: CHECK_STRUCT_HAS_MEMBER("struct timeval" tv_sec sys/select.h  HAVE_TIMEVAL_TV_SEC
       LANGUAGE C)

   CheckSymbolExists
       Check if a symbol exists as a function, variable, or macro

       CHECK_SYMBOL_EXISTS(<symbol> <files> <variable>)

       Check  that  the  <symbol> is available after including given header <files> and store the
       result  in  a  <variable>.   Specify  the  list  of   files   in   one   argument   as   a
       semicolon-separated list.  <variable> will be created as an internal cache variable.

       If the header files define the symbol as a macro it is considered available and assumed to
       work.  If the header files declare the symbol as a function or variable  then  the  symbol
       must  also be available for linking.  If the symbol is a type or enum value it will not be
       recognized (consider using CheckTypeSize or CheckCSourceCompiles).  If the check needs  to
       be  done  in  C++,  consider  using  CHECK_CXX_SYMBOL_EXISTS(),  which  does  the  same as
       CHECK_SYMBOL_EXISTS(), but in C++.

       The following variables may be set before calling this macro to modify the way  the  check
       is run:

          CMAKE_REQUIRED_FLAGS = string of compile command line flags
          CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
          CMAKE_REQUIRED_INCLUDES = list of include directories
          CMAKE_REQUIRED_LIBRARIES = list of libraries to link
          CMAKE_REQUIRED_QUIET = execute quietly without messages

   CheckTypeSize
       Check sizeof a type

          CHECK_TYPE_SIZE(TYPE VARIABLE [BUILTIN_TYPES_ONLY]
                                        [LANGUAGE <language>])

       Check  if the type exists and determine its size.  On return, "HAVE_${VARIABLE}" holds the
       existence of the type, and "${VARIABLE}" holds one of the following:

          <size> = type has non-zero size <size>
          "0"    = type has arch-dependent size (see below)
          ""     = type does not exist

       Both HAVE_${VARIABLE} and ${VARIABLE} will be created as internal cache variables.

       Furthermore, the variable "${VARIABLE}_CODE" holds C preprocessor code to define the macro
       "${VARIABLE}"  to  the size of the type, or leave the macro undefined if the type does not
       exist.

       The  variable  "${VARIABLE}"  may  be  "0"  when  CMAKE_OSX_ARCHITECTURES   has   multiple
       architectures  for  building  OS  X universal binaries.  This indicates that the type size
       varies across architectures.  In this  case  "${VARIABLE}_CODE"  contains  C  preprocessor
       tests  mapping  from  each architecture macro to the corresponding type size.  The list of
       architecture macros is stored in "${VARIABLE}_KEYS", and the value for each key is  stored
       in "${VARIABLE}-${KEY}".

       If the BUILTIN_TYPES_ONLY option is not given, the macro checks for headers <sys/types.h>,
       <stdint.h>, and <stddef.h>, and saves  results  in  HAVE_SYS_TYPES_H,  HAVE_STDINT_H,  and
       HAVE_STDDEF_H.   The  type  size  check automatically includes the available headers, thus
       supporting checks of types defined in the headers.

       If LANGUAGE is set, the specified compiler will be used to perform the  check.  Acceptable
       values are C and CXX

       Despite  the  name  of  the  macro  you  may  use  it  to  check  the size of more complex
       expressions, too.  To check e.g.  for the size of a struct member  you  can  do  something
       like this:

          check_type_size("((struct something*)0)->member" SIZEOF_MEMBER)

       The  following  variables may be set before calling this macro to modify the way the check
       is run:

          CMAKE_REQUIRED_FLAGS = string of compile command line flags
          CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
          CMAKE_REQUIRED_INCLUDES = list of include directories
          CMAKE_REQUIRED_LIBRARIES = list of libraries to link
          CMAKE_REQUIRED_QUIET = execute quietly without messages
          CMAKE_EXTRA_INCLUDE_FILES = list of extra headers to include

   CheckVariableExists
       Check if the variable exists.

          CHECK_VARIABLE_EXISTS(VAR VARIABLE)

          VAR      - the name of the variable
          VARIABLE - variable to store the result
                     Will be created as an internal cache variable.

       This macro is only for C variables.

       The following variables may be set before calling this macro to modify the way  the  check
       is run:

          CMAKE_REQUIRED_FLAGS = string of compile command line flags
          CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
          CMAKE_REQUIRED_LIBRARIES = list of libraries to link
          CMAKE_REQUIRED_QUIET = execute quietly without messages

   CMakeAddFortranSubdirectory
       Use MinGW gfortran from VS if a fortran compiler is not found.

       The  'add_fortran_subdirectory'  function adds a subdirectory to a project that contains a
       fortran only sub-project.  The module will check the current compiler and see  if  it  can
       support  fortran.   If  no  fortran  compiler is found and the compiler is MSVC, then this
       module will find the MinGW gfortran.  It will then use an external project to  build  with
       the  MinGW  tools.   It will also create imported targets for the libraries created.  This
       will only work if the fortran code is built into a dll, so BUILD_SHARED_LIBS is turned  on
       in  the  project.   In addition the CMAKE_GNUtoMS option is set to on, so that the MS .lib
       files are created.  Usage is as follows:

          cmake_add_fortran_subdirectory(
           <subdir>                # name of subdirectory
           PROJECT <project_name>  # project name in subdir top CMakeLists.txt
           ARCHIVE_DIR <dir>       # dir where project places .lib files
           RUNTIME_DIR <dir>       # dir where project places .dll files
           LIBRARIES <lib>...      # names of library targets to import
           LINK_LIBRARIES          # link interface libraries for LIBRARIES
            [LINK_LIBS <lib> <dep>...]...
           CMAKE_COMMAND_LINE ...  # extra command line flags to pass to cmake
           NO_EXTERNAL_INSTALL     # skip installation of external project
           )

       Relative paths in ARCHIVE_DIR and RUNTIME_DIR are interpreted with respect  to  the  build
       directory corresponding to the source directory in which the function is invoked.

       Limitations:

       NO_EXTERNAL_INSTALL  is  required  for  forward  compatibility  with a future version that
       supports installation of the external project binaries during "make install".

   CMakeBackwardCompatibilityCXX
       define a bunch of backwards compatibility variables

          CMAKE_ANSI_CXXFLAGS - flag for ansi c++
          CMAKE_HAS_ANSI_STRING_STREAM - has <strstream>
          include(TestForANSIStreamHeaders)
          include(CheckIncludeFileCXX)
          include(TestForSTDNamespace)
          include(TestForANSIForScope)

   CMakeDependentOption
       Macro to provide an option dependent on other options.

       This macro presents an option to the user only if a set  of  other  conditions  are  true.
       When the option is not presented a default value is used, but any value set by the user is
       preserved for when the option is presented again.  Example invocation:

          CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
                                 "USE_BAR;NOT USE_ZOT" OFF)

       If USE_BAR is true and USE_ZOT is false, this  provides  an  option  called  USE_FOO  that
       defaults  to  ON.  Otherwise, it sets USE_FOO to OFF.  If the status of USE_BAR or USE_ZOT
       ever changes, any value for the USE_FOO option  is  saved  so  that  when  the  option  is
       re-enabled it retains its old value.

   CMakeDetermineVSServicePack
       Deprecated.  Do not use.

       The  functionality of this module has been superseded by the CMAKE_<LANG>_COMPILER_VERSION
       variable that contains the compiler version number.

       Determine the Visual Studio service pack of the 'cl' in use.

       Usage:

          if(MSVC)
            include(CMakeDetermineVSServicePack)
            DetermineVSServicePack( my_service_pack )
            if( my_service_pack )
              message(STATUS "Detected: ${my_service_pack}")
            endif()
          endif()

       Function DetermineVSServicePack sets the given variable to one of the following values  or
       an empty string if unknown:

          vc80, vc80sp1
          vc90, vc90sp1
          vc100, vc100sp1
          vc110, vc110sp1, vc110sp2, vc110sp3, vc110sp4

   CMakeExpandImportedTargets
       Deprecated.  Do not use.

       This  module  was  once needed to expand imported targets to the underlying libraries they
       reference on disk for use with the try_compile() and try_run() commands.   These  commands
       now  support  imported  libraries  in their LINK_LIBRARIES options (since CMake 2.8.11 for
       try_compile() and since CMake 3.2 for try_run()).

       This  module  does  not  support  the  policy  CMP0022  NEW  behavior  or   use   of   the
       INTERFACE_LINK_LIBRARIES property because generator expressions cannot be evaluated during
       configuration.

          CMAKE_EXPAND_IMPORTED_TARGETS(<var> LIBRARIES lib1 lib2...libN
                                        [CONFIGURATION <config>])

       CMAKE_EXPAND_IMPORTED_TARGETS() takes a  list  of  libraries  and  replaces  all  imported
       targets contained in this list with their actual file paths of the referenced libraries on
       disk, including the libraries from their link interfaces.  If a CONFIGURATION is given, it
       uses  the  respective  configuration  of  the  imported  targets  if  it  exists.   If  no
       CONFIGURATION is given, it uses the first configuration from  ${CMAKE_CONFIGURATION_TYPES}
       if set, otherwise ${CMAKE_BUILD_TYPE}.

          cmake_expand_imported_targets(expandedLibs
            LIBRARIES ${CMAKE_REQUIRED_LIBRARIES}
            CONFIGURATION "${CMAKE_TRY_COMPILE_CONFIGURATION}" )

   CMakeFindDependencyMacro
          find_dependency(<dep> [<version> [EXACT]])

       find_dependency()  wraps a find_package() call for a package dependency. It is designed to
       be used in a <package>Config.cmake file, and it forwards the correct parameters for EXACT,
       QUIET and REQUIRED which were passed to the original find_package() call.  It also sets an
       informative diagnostic message if the dependency could not be found.

   CMakeFindFrameworks
       helper module to find OSX frameworks

   CMakeFindPackageMode
       This file is executed by cmake when invoked with  --find-package.   It  expects  that  the
       following variables are set using -D:

       NAME   name of the package

       COMPILER_ID
              the CMake compiler ID for which the result is, i.e. GNU/Intel/Clang/MSVC, etc.

       LANGUAGE
              language for which the result will be used, i.e. C/CXX/Fortan/ASM

       MODE

              EXIST  only check for existence of the given package

              COMPILE
                     print  the  flags  needed  for compiling an object file which uses the given
                     package

              LINK   print the flags needed for linking when using the given package

       QUIET  if TRUE, don't print anything

   CMakeForceCompiler
       Discouraged.  Avoid using this module if possible.  It will  be  deprecated  by  a  future
       version of CMake once alternatives have been provided for all toolchain file use cases.

       The macros provided by this module were once intended for use by cross-compiling toolchain
       files when CMake was not able to automatically detect the compiler identification.   Since
       the  introduction  of  this  module,  CMake's  compiler  identification  capabilities have
       improved and can now be taught to recognize  any  compiler.   Furthermore,  the  suite  of
       information CMake detects from a compiler is now too extensive to be provided by toolchain
       files using these macros.

       The only known remaining use case for  these  macros  is  to  write  toolchain  files  for
       cross-compilers  that cannot link binaries without special flags or custom linker scripts.
       These macros cause CMake to skip checks  it  normally  performs  as  part  of  enabling  a
       language  and  introspecting the toolchain.  However, skipping these checks may limit some
       generation functionality.

                                                  ----

       Macro CMAKE_FORCE_C_COMPILER has the following signature:

          CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)

       It  sets  CMAKE_C_COMPILER  to  the  given  compiler  and  the  cmake  internal   variable
       CMAKE_C_COMPILER_ID  to  the  given  compiler-id.   It also bypasses the check for working
       compiler and basic compiler information tests.

       Macro CMAKE_FORCE_CXX_COMPILER has the following signature:

          CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>)

       It sets  CMAKE_CXX_COMPILER  to  the  given  compiler  and  the  cmake  internal  variable
       CMAKE_CXX_COMPILER_ID  to  the  given compiler-id.  It also bypasses the check for working
       compiler and basic compiler information tests.

       Macro CMAKE_FORCE_Fortran_COMPILER has the following signature:

          CMAKE_FORCE_Fortran_COMPILER(<compiler> <compiler-id>)

       It sets CMAKE_Fortran_COMPILER to the given  compiler  and  the  cmake  internal  variable
       CMAKE_Fortran_COMPILER_ID  to  the  given  compiler-id.   It  also  bypasses the check for
       working compiler and basic compiler information tests.

       So a simple toolchain file could look like this:

          include (CMakeForceCompiler)
          set(CMAKE_SYSTEM_NAME Generic)
          CMAKE_FORCE_C_COMPILER   (chc12 MetrowerksHicross)
          CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross)

   CMakeGraphVizOptions
       The builtin graphviz support of CMake.

   Variables specific to the graphviz support
       CMake can generate graphviz files, showing the  dependencies  between  the  targets  in  a
       project  and also external libraries which are linked against.  When CMake is run with the
       --graphviz=foo option, it will produce

       • a foo.dot file showing all dependencies in the project

       • a foo.dot.<target> file for each  target,  file  showing  on  which  other  targets  the
         respective target depends

       • a  foo.dot.<target>.dependers file, showing which other targets depend on the respective
         target

       This can result in huge graphs.  Using the file CMakeGraphVizOptions.cmake  the  look  and
       content  of  the  generated  graphs  can  be  influenced.   This file is searched first in
       ${CMAKE_BINARY_DIR} and then in  ${CMAKE_SOURCE_DIR}.   If  found,  it  is  read  and  the
       variables set in it are used to adjust options for the generated graphviz files.

       GRAPHVIZ_GRAPH_TYPE
              The graph type

              • Mandatory : NO

              • Default   : "digraph"

       GRAPHVIZ_GRAPH_NAME
              The graph name.

              • Mandatory : NO

              • Default   : "GG"

       GRAPHVIZ_GRAPH_HEADER
              The header written at the top of the graphviz file.

              • Mandatory : NO

              • Default   : "node [n  fontsize = "12"];"

       GRAPHVIZ_NODE_PREFIX
              The prefix for each node in the graphviz file.

              • Mandatory : NO

              • Default   : "node"

       GRAPHVIZ_EXECUTABLES
              Set this to FALSE to exclude executables from the generated graphs.

              • Mandatory : NO

              • Default   : TRUE

       GRAPHVIZ_STATIC_LIBS
              Set this to FALSE to exclude static libraries from the generated graphs.

              • Mandatory : NO

              • Default   : TRUE

       GRAPHVIZ_SHARED_LIBS
              Set this to FALSE to exclude shared libraries from the generated graphs.

              • Mandatory : NO

              • Default   : TRUE

       GRAPHVIZ_MODULE_LIBS
              Set this to FALSE to exclude module libraries from the generated graphs.

              • Mandatory : NO

              • Default   : TRUE

       GRAPHVIZ_EXTERNAL_LIBS
              Set this to FALSE to exclude external libraries from the generated graphs.

              • Mandatory : NO

              • Default   : TRUE

       GRAPHVIZ_IGNORE_TARGETS
              A list of regular expressions for ignoring targets.

              • Mandatory : NO

              • Default   : empty

       GRAPHVIZ_GENERATE_PER_TARGET
              Set this to FALSE to exclude per target graphs foo.dot.<target>.

              • Mandatory : NO

              • Default   : TRUE

       GRAPHVIZ_GENERATE_DEPENDERS
              Set this to FALSE to exclude depender graphs foo.dot.<target>.dependers.

              • Mandatory : NO

              • Default   : TRUE

   CMakePackageConfigHelpers
       Helpers functions for creating config files that can be included by other projects to find
       and use a package.

       Adds the configure_package_config_file() and write_basic_package_version_file() commands.

   Generating a Package Configuration File
       configure_package_config_file
              Create a config file for a project:

                 configure_package_config_file(<input> <output>
                   INSTALL_DESTINATION <path>
                   [PATH_VARS <var1> <var2> ... <varN>]
                   [NO_SET_AND_CHECK_MACRO]
                   [NO_CHECK_REQUIRED_COMPONENTS_MACRO]
                   [INSTALL_PREFIX <path>]
                   )

       configure_package_config_file() should be  used  instead  of  the  plain  configure_file()
       command  when creating the <Name>Config.cmake or <Name>-config.cmake file for installing a
       project or library.  It  helps  making  the  resulting  package  relocatable  by  avoiding
       hardcoded paths in the installed Config.cmake file.

       In  a  FooConfig.cmake  file  there may be code like this to make the install destinations
       know to the using project:

          set(FOO_INCLUDE_DIR   "@CMAKE_INSTALL_FULL_INCLUDEDIR@" )
          set(FOO_DATA_DIR   "@CMAKE_INSTALL_PREFIX@/@RELATIVE_DATA_INSTALL_DIR@" )
          set(FOO_ICONS_DIR   "@CMAKE_INSTALL_PREFIX@/share/icons" )
          ...logic to determine installedPrefix from the own location...
          set(FOO_CONFIG_DIR  "${installedPrefix}/@CONFIG_INSTALL_DIR@" )

       All 4 options shown above are not sufficient, since the  first  3  hardcode  the  absolute
       directory  locations,  and  the  4th  case  works  only  if  the  logic  to  determine the
       installedPrefix is correct, and if CONFIG_INSTALL_DIR contains a relative path,  which  in
       general cannot be guaranteed.  This has the effect that the resulting FooConfig.cmake file
       would work poorly under Windows and OSX, where  users  are  used  to  choose  the  install
       location  of  a  binary package at install time, independent from how CMAKE_INSTALL_PREFIX
       was set at build/cmake time.

       Using configure_package_config_file helps.  If used  correctly,  it  makes  the  resulting
       FooConfig.cmake file relocatable.  Usage:

       1. write a FooConfig.cmake.in file as you are used to

       2. insert a line containing only the string @PACKAGE_INIT@

       3. instead       of      set(FOO_DIR      "@SOME_INSTALL_DIR@"),      use      set(FOO_DIR
          "@PACKAGE_SOME_INSTALL_DIR@") (this must be after the @PACKAGE_INIT@ line)

       4. instead of using the normal configure_file(), use configure_package_config_file()

       The <input> and <output> arguments are the input and output  file,  the  same  way  as  in
       configure_file().

       The  <path> given to INSTALL_DESTINATION must be the destination where the FooConfig.cmake
       file will be installed to.   This  path  can  either  be  absolute,  or  relative  to  the
       INSTALL_PREFIX path.

       The  variables <var1> to <varN> given as PATH_VARS are the variables which contain install
       destinations.  For each of them the macro will create a helper variable  PACKAGE_<var...>.
       These  helper  variables  must  be  used  in  the  FooConfig.cmake.in file for setting the
       installed location.  They are calculated by configure_package_config_file so that they are
       always  relative  to  the installed location of the package.  This works both for relative
       and also for absolute locations.  For absolute locations it works  only  if  the  absolute
       location is a subdirectory of INSTALL_PREFIX.

       If  the  INSTALL_PREFIX argument is passed, this is used as base path to calculate all the
       relative paths.  The <path> argument must be an absolute path.  If this  argument  is  not
       passed, the CMAKE_INSTALL_PREFIX variable will be used instead.  The default value is good
       when generating a FooConfig.cmake file to use your package from the  install  tree.   When
       generating  a  FooConfig.cmake  file  to  use your package from the build tree this option
       should be used.

       By default configure_package_config_file also generates two helper macros, set_and_check()
       and check_required_components() into the FooConfig.cmake file.

       set_and_check() should be used instead of the normal set() command for setting directories
       and file locations.  Additionally  to  setting  the  variable  it  also  checks  that  the
       referenced file or directory actually exists and fails with a FATAL_ERROR otherwise.  This
       makes sure that the created FooConfig.cmake file does not contain wrong references.   When
       using  the  NO_SET_AND_CHECK_MACRO,  this  macro is not generated into the FooConfig.cmake
       file.

       check_required_components(<package_name>)  should  be   called   at   the   end   of   the
       FooConfig.cmake  file  if  the package supports components.  This macro checks whether all
       requested, non-optional components have been found, and if this is not the case, sets  the
       Foo_FOUND  variable  to FALSE, so that the package is considered to be not found.  It does
       that by testing the Foo_<Component>_FOUND variables for all requested required components.
       When using the NO_CHECK_REQUIRED_COMPONENTS_MACRO option, this macro is not generated into
       the FooConfig.cmake file.

       For an example see below the documentation for write_basic_package_version_file().

   Generating a Package Version File
       write_basic_package_version_file
              Create a version file for a project:

                 write_basic_package_version_file(<filename>
                   [VERSION <major.minor.patch>]
                   COMPATIBILITY <AnyNewerVersion|SameMajorVersion|ExactVersion> )

       Writes a file for  use  as  <package>ConfigVersion.cmake  file  to  <filename>.   See  the
       documentation of find_package() for details on this.

       <filename> is the output filename, it should be in the build tree.  <major.minor.patch> is
       the version number of the project to be installed.

       If no VERSION is given, the PROJECT_VERSION variable is used.  If this hasn't been set, it
       errors out.

       The  COMPATIBILITY  mode  AnyNewerVersion means that the installed package version will be
       considered compatible if it is newer or exactly the same as the requested  version.   This
       mode  should  be  used for packages which are fully backward compatible, also across major
       versions.   If  SameMajorVersion  is  used  instead,  then  the  behaviour  differs   from
       AnyNewerVersion  in  that  the  major  version  number must be the same as requested, e.g.
       version 2.0 will not be considered compatible if 1.0 is requested.  This  mode  should  be
       used  for  packages  which guarantee backward compatibility within the same major version.
       If ExactVersion is used, then the package is only considered compatible if  the  requested
       version  matches  exactly its own version number (not considering the tweak version).  For
       example, version 1.2.3 of a package is only considered  compatible  to  requested  version
       1.2.3.   This  mode is for packages without compatibility guarantees.  If your project has
       more  elaborated  version  matching  rules,  you  will  need  to  write  your  own  custom
       ConfigVersion.cmake file instead of using this macro.

       Internally,  this  macro  executes  configure_file() to create the resulting version file.
       Depending        on        the        COMPATIBLITY,        either         the         file
       BasicConfigVersion-SameMajorVersion.cmake.in                                            or
       BasicConfigVersion-AnyNewerVersion.cmake.in is used.  Please note that these two files are
       internal  to CMake and you should not call configure_file() on them yourself, but they can
       be used as starting point to create more sophisticted custom ConfigVersion.cmake files.

   Example Generating Package Files
       Example using both configure_package_config_file() and write_basic_package_version_file():

       CMakeLists.txt:

          set(INCLUDE_INSTALL_DIR include/ ... CACHE )
          set(LIB_INSTALL_DIR lib/ ... CACHE )
          set(SYSCONFIG_INSTALL_DIR etc/foo/ ... CACHE )
          ...
          include(CMakePackageConfigHelpers)
          configure_package_config_file(FooConfig.cmake.in
            ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake
            INSTALL_DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake
            PATH_VARS INCLUDE_INSTALL_DIR SYSCONFIG_INSTALL_DIR)
          write_basic_package_version_file(
            ${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake
            VERSION 1.2.3
            COMPATIBILITY SameMajorVersion )
          install(FILES ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake
                        ${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake
                  DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake )

       FooConfig.cmake.in:

          set(FOO_VERSION x.y.z)
          ...
          @PACKAGE_INIT@
          ...
          set_and_check(FOO_INCLUDE_DIR "@PACKAGE_INCLUDE_INSTALL_DIR@")
          set_and_check(FOO_SYSCONFIG_DIR "@PACKAGE_SYSCONFIG_INSTALL_DIR@")

          check_required_components(Foo)

   CMakeParseArguments
       This module once implemented the cmake_parse_arguments() command that is  now  implemented
       natively  by  CMake.   It is now an empty placeholder for compatibility with projects that
       include it to get the command from CMake 3.4 and lower.

   CMakePrintHelpers
       Convenience macros for printing properties and variables, useful e.g. for debugging.

          CMAKE_PRINT_PROPERTIES([TARGETS target1 ..  targetN]
                                 [SOURCES source1 .. sourceN]
                                 [DIRECTORIES dir1 .. dirN]
                                 [TESTS test1 .. testN]
                                 [CACHE_ENTRIES entry1 .. entryN]
                                 PROPERTIES prop1 .. propN )

       This macro prints the values of  the  properties  of  the  given  targets,  source  files,
       directories,  tests  or  cache  entries.   Exactly one of the scope keywords must be used.
       Example:

          cmake_print_properties(TARGETS foo bar PROPERTIES
                                 LOCATION INTERFACE_INCLUDE_DIRS)

       This will print the LOCATION and INTERFACE_INCLUDE_DIRS properties for  both  targets  foo
       and bar.

       CMAKE_PRINT_VARIABLES(var1 var2 ..  varN)

       This macro will print the name of each variable followed by its value.  Example:

          cmake_print_variables(CMAKE_C_COMPILER CMAKE_MAJOR_VERSION DOES_NOT_EXIST)

       Gives:

          -- CMAKE_C_COMPILER="/usr/bin/gcc" ; CMAKE_MAJOR_VERSION="2" ; DOES_NOT_EXIST=""

   CMakePrintSystemInformation
       print system information

       This  file can be used for diagnostic purposes just include it in a project to see various
       internal CMake variables.

   CMakePushCheckState
       This module defines three  macros:  CMAKE_PUSH_CHECK_STATE()  CMAKE_POP_CHECK_STATE()  and
       CMAKE_RESET_CHECK_STATE() These macros can be used to save, restore and reset (i.e., clear
       contents) the state of  the  variables  CMAKE_REQUIRED_FLAGS,  CMAKE_REQUIRED_DEFINITIONS,
       CMAKE_REQUIRED_LIBRARIES  and  CMAKE_REQUIRED_INCLUDES  used  by  the  various Check-files
       coming with CMake, like e.g.  check_function_exists()  etc.   The  variable  contents  are
       pushed  on  a  stack,  pushing  multiple  times  is  supported.  This is useful e.g.  when
       executing such tests in  a  Find-module,  where  they  have  to  be  set,  but  after  the
       Find-module has been executed they should have the same value as they had before.

       CMAKE_PUSH_CHECK_STATE()  macro receives optional argument RESET.  Whether it's specified,
       CMAKE_PUSH_CHECK_STATE() will set all CMAKE_REQUIRED_* variables to empty values, same  as
       CMAKE_RESET_CHECK_STATE() call will do.

       Usage:

          cmake_push_check_state(RESET)
          set(CMAKE_REQUIRED_DEFINITIONS -DSOME_MORE_DEF)
          check_function_exists(...)
          cmake_reset_check_state()
          set(CMAKE_REQUIRED_DEFINITIONS -DANOTHER_DEF)
          check_function_exists(...)
          cmake_pop_check_state()

   CMakeVerifyManifest
       CMakeVerifyManifest.cmake

       This  script  is  used  to  verify that embeded manifests and side by side manifests for a
       project match.  To run this script, cd to a directory and run the script  with  cmake  -P.
       On  the  command  line  you  can  pass  in  versions  that are OK even if not found in the
       .manifest      files.       For      example,      cmake      -Dallow_versions=8.0.50608.0
       -PCmakeVerifyManifest.cmake  could  be used to allow an embeded manifest of 8.0.50608.0 to
       be used in a project even if that version was not found in the .manifest file.

   CPackBundle
       CPack Bundle generator (Mac OS X) specific options

   Variables specific to CPack Bundle generator
       Installers built on Mac OS X using the Bundle generator use the  aforementioned  DragNDrop
       (CPACK_DMG_xxx)    variables,    plus    the    following    Bundle-specific    parameters
       (CPACK_BUNDLE_xxx).

       CPACK_BUNDLE_NAME
              The name of the generated bundle. This appears in the  OSX  finder  as  the  bundle
              name. Required.

       CPACK_BUNDLE_PLIST
              Path  to an OSX plist file that will be used for the generated bundle. This assumes
              that the caller has generated or specified their own Info.plist file. Required.

       CPACK_BUNDLE_ICON
              Path to an OSX icon file that will be used as the icon for  the  generated  bundle.
              This is the icon that appears in the OSX finder for the bundle, and in the OSX dock
              when the bundle is opened.  Required.

       CPACK_BUNDLE_STARTUP_COMMAND
              Path to a startup script. This is a path to an executable or script  that  will  be
              run  whenever  an  end-user  double-clicks  the generated bundle in the OSX Finder.
              Optional.

       CPACK_BUNDLE_APPLE_CERT_APP
              The name of your Apple supplied code signing certificate for the application.   The
              name  usually  takes  the form "Developer ID Application: [Name]" or "3rd Party Mac
              Developer Application: [Name]". If this variable is not set  the  application  will
              not be signed.

       CPACK_BUNDLE_APPLE_ENTITLEMENTS
              The  name  of  the  plist file that contains your apple entitlements for sandboxing
              your application. This file is required for submission to the Mac App Store.

       CPACK_BUNDLE_APPLE_CODESIGN_FILES
              A list of additional files that you wish to be signed. You do not need to list  the
              main application folder, or the main executable. You should list any frameworks and
              plugins that are included in your app bundle.

       CPACK_BUNDLE_APPLE_CODESIGN_PARAMETER
              Additional parameter that will passed to codesign.  Default value: "--deep -f"

       CPACK_COMMAND_CODESIGN
              Path to the codesign(1) command used to sign applications with an Apple cert.  This
              variable can be used to override the automatically detected command (or specify its
              location if the auto-detection fails to find it.)

   CPackComponent
       Build binary and source package installers

   Variables concerning CPack Components
       The CPackComponent module is the module which handles the component part  of  CPack.   See
       CPack module for general information about CPack.

       For certain kinds of binary installers (including the graphical installers on Mac OS X and
       Windows), CPack generates installers that allow users  to  select  individual  application
       components  to  install.   The  contents  of  each of the components are identified by the
       COMPONENT argument of CMake's INSTALL command.  These components  can  be  annotated  with
       user-friendly  names  and descriptions, inter-component dependencies, etc., and grouped in
       various ways  to  customize  the  resulting  installer.   See  the  cpack_add_*  commands,
       described below, for more information about component-specific installations.

       Component-specific  installation  allows  users  to  select specific sets of components to
       install during the  install  process.   Installation  components  are  identified  by  the
       COMPONENT  argument  of  CMake's  INSTALL commands, and should be further described by the
       following CPack commands:

       CPACK_COMPONENTS_ALL
              The list of component to install.

              The default value of this variable is computed by CPack and contains all components
              defined  by  the  project.   The  user  may  set  it  to only include the specified
              components.

       CPACK_<GENNAME>_COMPONENT_INSTALL
              Enable/Disable component install for CPack generator <GENNAME>.

              Each CPack Generator (RPM, DEB, ARCHIVE, NSIS, DMG, etc...) has  a  legacy  default
              behavior.   e.g.   RPM  builds  monolithic  whereas NSIS builds component.  One can
              change the default behavior by setting this variable to 0/1 or OFF/ON.

       CPACK_COMPONENTS_GROUPING
              Specify  how  components  are  grouped  for  multi-package  component-aware   CPack
              generators.

              Some  generators  like  RPM  or  ARCHIVE  family  (TGZ, ZIP, ...) generates several
              packages files when asked  for  component  packaging.   They  group  the  component
              differently depending on the value of this variable:

              • ONE_PER_GROUP (default): creates one package file per component group

              • ALL_COMPONENTS_IN_ONE : creates a single package with all (requested) component

              • IGNORE : creates one package per component, i.e. IGNORE component group

              One  can  specify  different  grouping  for  different  CPack  generator by using a
              CPACK_PROJECT_CONFIG_FILE.

       CPACK_COMPONENT_<compName>_DISPLAY_NAME
              The name to be displayed for a component.

       CPACK_COMPONENT_<compName>_DESCRIPTION
              The description of a component.

       CPACK_COMPONENT_<compName>_GROUP
              The group of a component.

       CPACK_COMPONENT_<compName>_DEPENDS
              The dependencies (list of components) on which this component depends.

       CPACK_COMPONENT_<compName>_REQUIRED
              True is this component is required.

       cpack_add_component

       Describes a CPack installation component named  by  the  COMPONENT  argument  to  a  CMake
       INSTALL command.

          cpack_add_component(compname
                              [DISPLAY_NAME name]
                              [DESCRIPTION description]
                              [HIDDEN | REQUIRED | DISABLED ]
                              [GROUP group]
                              [DEPENDS comp1 comp2 ... ]
                              [INSTALL_TYPES type1 type2 ... ]
                              [DOWNLOADED]
                              [ARCHIVE_FILE filename])

       The  cmake_add_component  command  describes an installation component, which the user can
       opt to install or remove as part of the graphical installation process.  compname  is  the
       name  of the component, as provided to the COMPONENT argument of one or more CMake INSTALL
       commands.

       DISPLAY_NAME is the displayed name of the  component,  used  in  graphical  installers  to
       display the component name.  This value can be any string.

       DESCRIPTION  is  an extended description of the component, used in graphical installers to
       give the user additional information about the component.  Descriptions can span  multiple
       lines  using  \n  as  the line separator.  Typically, these descriptions should be no more
       than a few lines long.

       HIDDEN indicates that this component will be hidden in the graphical  installer,  so  that
       the user cannot directly change whether it is installed or not.

       REQUIRED  indicates  that  this  component  is  required,  and  therefore  will  always be
       installed.  It will be visible in the graphical installer, but it  cannot  be  unselected.
       (Typically, required components are shown greyed out).

       DISABLED  indicates  that  this component should be disabled (unselected) by default.  The
       user is free to select this component for installation, unless it is also HIDDEN.

       DEPENDS lists the components on which  this  component  depends.   If  this  component  is
       selected,  then  each  of  the  components  listed  must also be selected.  The dependency
       information is  encoded  within  the  installer  itself,  so  that  users  cannot  install
       inconsistent sets of components.

       GROUP  names  the component group of which this component is a part.  If not provided, the
       component will be a standalone component, not part  of  any  component  group.   Component
       groups are described with the cpack_add_component_group command, detailed below.

       INSTALL_TYPES lists the installation types of which this component is a part.  When one of
       these installations types is selected, this  component  will  automatically  be  selected.
       Installation types are described with the cpack_add_install_type command, detailed below.

       DOWNLOADED indicates that this component should be downloaded on-the-fly by the installer,
       rather than packaged in  with  the  installer  itself.   For  more  information,  see  the
       cpack_configure_downloads command.

       ARCHIVE_FILE  provides  a  name  for  the  archive  file  created  by CPack to be used for
       downloaded components.  If not supplied, CPack will create a file with some name based  on
       CPACK_PACKAGE_FILE_NAME  and the name of the component.  See cpack_configure_downloads for
       more information.

       cpack_add_component_group

       Describes a group of related CPack installation components.

          cpack_add_component_group(groupname
                                   [DISPLAY_NAME name]
                                   [DESCRIPTION description]
                                   [PARENT_GROUP parent]
                                   [EXPANDED]
                                   [BOLD_TITLE])

       The cpack_add_component_group describes a group of installation components, which will  be
       placed together within the listing of options.  Typically, component groups allow the user
       to select/deselect all of the components within a single group via  a  single  group-level
       option.   Use  component  groups to reduce the complexity of installers with many options.
       groupname is an arbitrary name used to identify the group in the  GROUP  argument  of  the
       cpack_add_component  command,  which is used to place a component in a group.  The name of
       the group must not conflict with the name of any component.

       DISPLAY_NAME is the displayed name of the component group, used in graphical installers to
       display the component group name.  This value can be any string.

       DESCRIPTION  is  an  extended  description  of  the  component  group,  used  in graphical
       installers to give the user additional information about the components within that group.
       Descriptions  can  span  multiple  lines using \n as the line separator.  Typically, these
       descriptions should be no more than a few lines long.

       PARENT_GROUP, if supplied, names the parent group of this group.  Parent groups  are  used
       to establish a hierarchy of groups, providing an arbitrary hierarchy of groups.

       EXPANDED  indicates  that, by default, the group should show up as "expanded", so that the
       user immediately sees all of the components within the group.  Otherwise, the  group  will
       initially show up as a single entry.

       BOLD_TITLE  indicates  that  the  group  title  should  appear in bold, to call the user's
       attention to the group.

       cpack_add_install_type

       Add a new installation type containing a set of predefined  component  selections  to  the
       graphical installer.

          cpack_add_install_type(typename
                                 [DISPLAY_NAME name])

       The  cpack_add_install_type  command  identifies  a  set  of  preselected  components that
       represents a common use case for an application.  For example, a "Developer" install  type
       might  include an application along with its header and library files, while an "End user"
       install type might just include the application's executable.  Each  component  identifies
       itself   with   one   or   more   install   types   via   the  INSTALL_TYPES  argument  to
       cpack_add_component.

       DISPLAY_NAME is the displayed name of the install type, which will typically show up in  a
       drop-down box within a graphical installer.  This value can be any string.

       cpack_configure_downloads

       Configure  CPack  to  download  selected components on-the-fly as part of the installation
       process.

          cpack_configure_downloads(site
                                    [UPLOAD_DIRECTORY dirname]
                                    [ALL]
                                    [ADD_REMOVE|NO_ADD_REMOVE])

       The cpack_configure_downloads command configures installation-time downloads  of  selected
       components.   For each downloadable component, CPack will create an archive containing the
       contents of that component, which should be uploaded to the given  site.   When  the  user
       selects  that  component  for  installation,  the  installer will download and extract the
       component in place.  This feature is  useful  for  creating  small  installers  that  only
       download  the  requested  components,  saving bandwidth.  Additionally, the installers are
       small enough that they will be installed as part of the normal installation  process,  and
       the  "Change" button in Windows Add/Remove Programs control panel will allow one to add or
       remove parts of  the  application  after  the  original  installation.   On  Windows,  the
       downloaded-components functionality requires the ZipDLL plug-in for NSIS, available at:

          http://nsis.sourceforge.net/ZipDLL_plug-in

       On  Mac  OS  X,  installers  that  download  components  on-the-fly  can only be built and
       installed on system using Mac OS X 10.5 or later.

       The site argument is a URL where the archives for  downloadable  components  will  reside,
       e.g.,  https://cmake.org/files/2.6.1/installer/  All  of  the  archives  produced by CPack
       should be uploaded to that location.

       UPLOAD_DIRECTORY is the local directory where CPack will create the various  archives  for
       each  of  the components.  The contents of this directory should be uploaded to a location
       accessible by the URL given in  the  site  argument.   If  omitted,  CPack  will  use  the
       directory CPackUploads inside the CMake binary directory to store the generated archives.

       The  ALL  flag  indicates  that  all  components  be  downloaded.   Otherwise,  only those
       components explicitly marked as DOWNLOADED or that have a specified ARCHIVE_FILE  will  be
       downloaded.   Additionally,  the  ALL  option  implies ADD_REMOVE (unless NO_ADD_REMOVE is
       specified).

       ADD_REMOVE indicates that CPack should install a copy of the installer that can be  called
       from  Windows'  Add/Remove  Programs dialog (via the "Modify" button) to change the set of
       installed components.  NO_ADD_REMOVE turns off this behavior.  This option is  ignored  on
       Mac OS X.

   CPackCygwin
       Cygwin CPack generator (Cygwin).

   Variables specific to CPack Cygwin generator
       The following variable is specific to installers build on and/or for Cygwin:

       CPACK_CYGWIN_PATCH_NUMBER
              The Cygwin patch number.  FIXME: This documentation is incomplete.

       CPACK_CYGWIN_PATCH_FILE
              The Cygwin patch file.  FIXME: This documentation is incomplete.

       CPACK_CYGWIN_BUILD_SCRIPT
              The Cygwin build script.  FIXME: This documentation is incomplete.

   CPackDeb
       The builtin (binary) CPack Deb generator (Unix only)

   Variables specific to CPack Debian (DEB) generator
       CPackDeb  may  be  used  to create Deb package using CPack.  CPackDeb is a CPack generator
       thus     it     uses     the     CPACK_XXX     variables     used     by      CPack      :
       https://cmake.org/Wiki/CMake:CPackConfiguration.   CPackDeb  generator  should work on any
       linux host but it will produce better deb package when Debian  specific  tools  'dpkg-xxx'
       are usable on the build system.

       CPackDeb  has  specific  features  which  are controlled by the specifics CPACK_DEBIAN_XXX
       variables.

       CPACK_DEBIAN_<COMPONENT>_XXXX variables may be used in order to  have  component  specific
       values.   Note however that <COMPONENT> refers to the grouping name written in upper case.
       It may be either a component name or a component GROUP name.

       You'll        find        a        detailed        usage        on        the        wiki:
       https://cmake.org/Wiki/CMake:CPackPackageGenerators#DEB_.28UNIX_only.29  .   However  as a
       handy reminder here comes the list of specific variables:

       CPACK_DEBIAN_PACKAGE_NAME

              NOTE:
                 If        CPACK_DEBIAN_PACKAGE_SHLIBDEPS        or       more       specifically
                 CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS  is  set  for  this  component,   the
                 discovered         dependencies         will        be        appended        to
                 CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS               instead                of
                 CPACK_DEBIAN_PACKAGE_DEPENDS.  If CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS is an
                 empty string, only the automatically discovered dependencies  will  be  set  for
                 this component.

              Example:

                 set(CPACK_DEBIAN_PACKAGE_DEPENDS "libc6 (>= 2.3.1-6), libc6 (< 2.4)")

       CPACK_DEBIAN_COMPRESSION_TYPE
              The  compression  used for creating the Debian package.  Possible values are: lzma,
              xz, bzip2 and gzip.

              • Mandatory : YES

              • Default   : 'gzip'

       CPACK_DEBIAN_PACKAGE_PRIORITY

       CPACK_DEBIAN_<COMPONENT>_PACKAGE_PRIORITY

              from  which  the  original  source  can  be  obtained  and  any additional upstream
              documentation or information may be found.

              • Mandatory : NO

              • Default   : -

              NOTE:
                 The content of this field is a simple URL  without  any  surrounding  characters
                 such as <>.

       CPACK_DEBIAN_PACKAGE_SHLIBDEPS

       CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS
              May  be  set  to  ON  in  order  to  use  dpkg-shlibdeps to generate better package
              dependency list.

              • Mandatory : NO

              • Default   :

                • CPACK_DEBIAN_PACKAGE_SHLIBDEPS if set or

                • OFF

              NOTE:
                 You may need set CMAKE_INSTALL_RPATH to an appropriate value  if  you  use  this
                 feature,  because  if  you don't dpkg-shlibdeps may fail to find your own shared
                 libs.  See https://cmake.org/Wiki/CMake_RPATH_handling.

       CPACK_DEBIAN_PACKAGE_DEBUG
              May be set when invoking cpack in order to trace debug information during  CPackDeb

       CPACK_DEBIAN_PACKAGE_PREDEPENDS

       CPACK_DEBIAN_<COMPONENT>_PACKAGE_PREDEPENDS
              Sets  the  Pre-Depends  field  of the Debian package.  Like Depends, except that it
              also forces dpkg to  complete  installation  of  the  packages  named  before  even
              starting the installation of the package which declares the pre-dependency.

              • Mandatory : NO

              • Default   :

                • An empty string for non-component based installations

                • CPACK_DEBIAN_PACKAGE_PREDEPENDS for component-based installations.

              See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

       CPACK_DEBIAN_PACKAGE_ENHANCES

       CPACK_DEBIAN_<COMPONENT>_PACKAGE_ENHANCES
              Sets  the  Enhances  field of the Debian package.  Similar to Suggests but works in
              the opposite direction: declares that a package can enhance  the  functionality  of
              another package.

              • Mandatory : NO

              • Default   :

                • An empty string for non-component based installations

                • CPACK_DEBIAN_PACKAGE_ENHANCES for component-based installations.

              See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

       CPACK_DEBIAN_PACKAGE_BREAKS

       CPACK_DEBIAN_<COMPONENT>_PACKAGE_BREAKS
              Sets  the  Breaks  field of the Debian package.  When a binary package (P) declares
              that it breaks other packages (B), dpkg  will  not  allow  the  package  (P)  which
              declares  Breaks  be  unpacked  unless  the  packages  that  will be broken (B) are
              deconfigured first.  As long as the  package  (P)  is  configured,  the  previously
              deconfigured packages (B) cannot be reconfigured again.

              • Mandatory : NO

              • Default   :

                • An empty string for non-component based installations

                • CPACK_DEBIAN_PACKAGE_BREAKS for component-based installations.

              See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-breaks

       CPACK_DEBIAN_PACKAGE_CONFLICTS

       CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONFLICTS
              Sets the Conflicts field of the Debian package.  When one binary package declares a
              conflict with another using a Conflicts field, dpkg  will  not  allow  them  to  be
              unpacked on the system at the same time.

              • Mandatory : NO

              • Default   :

                • An empty string for non-component based installations

                • CPACK_DEBIAN_PACKAGE_CONFLICTS for component-based installations.

              See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-conflicts

              NOTE:
                 This  is  a  stronger restriction than Breaks, which prevents the broken package
                 from being configured while the breaking package is in the "Unpacked" state  but
                 allows both packages to be unpacked at the same time.

       CPACK_DEBIAN_PACKAGE_PROVIDES

       CPACK_DEBIAN_<COMPONENT>_PACKAGE_PROVIDES
              Sets  the  Provides  field  of  the Debian package.  A virtual package is one which
              appears in the Provides control field of another package.

              • Mandatory : NO

              • Default   :

                • An empty string for non-component based installations

                • CPACK_DEBIAN_PACKAGE_PROVIDES for component-based installations.

              See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-virtual

       CPACK_DEBIAN_PACKAGE_REPLACES

       CPACK_DEBIAN_<COMPONENT>_PACKAGE_REPLACES
              Sets the Replaces field of the Debian  package.   Packages  can  declare  in  their
              control  file  that  they  should  overwrite  files  in  certain other packages, or
              completely replace other packages.

              • Mandatory : NO

              • Default   :

                • An empty string for non-component based installations

                • CPACK_DEBIAN_PACKAGE_REPLACES for component-based installations.

              See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

       CPACK_DEBIAN_PACKAGE_RECOMMENDS

       CPACK_DEBIAN_<COMPONENT>_PACKAGE_RECOMMENDS
              Sets the Recommends field of the Debian package.   Allows  packages  to  declare  a
              strong, but not absolute, dependency on other packages.

              • Mandatory : NO

              • Default   :

                • An empty string for non-component based installations

                • CPACK_DEBIAN_PACKAGE_RECOMMENDS for component-based installations.

              See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

       CPACK_DEBIAN_PACKAGE_SUGGESTS

       CPACK_DEBIAN_<COMPONENT>_PACKAGE_SUGGESTS
              Sets  the  Suggests  field  of  the  Debian  package.  Allows packages to declare a
              suggested package install grouping.

              • Mandatory : NO

              • Default   :

                • An empty string for non-component based installations

                • CPACK_DEBIAN_PACKAGE_SUGGESTS for component-based installations.

              See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

       CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA

       CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_EXTRA
              This variable allow advanced user to  add  custom  script  to  the  control.tar.gz.
              Typical usage is for conffiles, postinst, postrm, prerm.

              • Mandatory : NO

              • Default   : -

              Usage:

                 set(CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA
                     "${CMAKE_CURRENT_SOURCE_DIR/prerm;${CMAKE_CURRENT_SOURCE_DIR}/postrm")

              NOTE:
                 The  original  permissions of the files will be used in the final package unless
                 the  variable   CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION   is   set.    In
                 particular,  the  scripts  should  have  the proper executable flag prior to the
                 generation of the package.

       CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION

       CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_STRICT_PERMISSION
              This variable indicates if the Debian policy on control files  should  be  strictly
              followed.

              • Mandatory : NO

              • Default   : FALSE

              Usage:

                 set(CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION TRUE)

              NOTE:
                 This overrides the permissions on the original files, following the rules set by
                 Debian                                                                    policy
                 https://www.debian.org/doc/debian-policy/ch-files.html#s-permissions-owners

       CPACK_DEBIAN_PACKAGE_SOURCE

       CPACK_DEBIAN_<COMPONENT>_PACKAGE_SOURCE
              Sets  the  Source field of the binary Debian package.  When the binary package name
              is  not  the  same  as  the  source  package  name  (in  particular  when   several
              components/binaries are generated from one source) the source from which the binary
              has been generated should be indicated with the field Source.

              • Mandatory : NO

              • Default   :

                • An empty string for non-component based installations

                • CPACK_DEBIAN_PACKAGE_SOURCE for component-based installations.

              See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Source

              NOTE:
                 This value is not interpreted. It is  possible  to  pass  an  optional  revision
                 number of the referenced source package as well.

   CPackDMG
       DragNDrop CPack generator (Mac OS X).

   Variables specific to CPack DragNDrop generator
       The following variables are specific to the DragNDrop installers built on Mac OS X:

       CPACK_DMG_VOLUME_NAME
              The volume name of the generated disk image. Defaults to CPACK_PACKAGE_FILE_NAME.

       CPACK_DMG_FORMAT
              The  disk  image  format.  Common  values  are  UDRO  (UDIF  read-only), UDZO (UDIF
              zlib-compressed) or UDBZ (UDIF bzip2-compressed).  Refer  to  hdiutil(1)  for  more
              information on other available formats.

       CPACK_DMG_DS_STORE
              Path to a custom DS_Store file. This .DS_Store file e.g. can be used to specify the
              Finder window position/geometry and layout (such as hidden toolbars,  placement  of
              the  icons  etc.).  This file has to be generated by the Finder (either manually or
              through AppleScript) using a normal folder from which the .DS_Store file  can  then
              be extracted.

       CPACK_DMG_DS_STORE_SETUP_SCRIPT
              Path  to  a  custom  AppleScript  file.   This  AppleScript  is  used to generate a
              .DS_Store file which specifies the Finder window position/geometry and layout (such
              as  hidden  toolbars,  placement  of  the  icons  etc.).   By  specifying  a custom
              AppleScript there is no need to use CPACK_DMG_DS_STORE, as the  .DS_Store  that  is
              generated by the AppleScript will be packaged.

       CPACK_DMG_BACKGROUND_IMAGE
              Path  to  an  image file to be used as the background.  This file will be copied to
              .background/background.<ext>, where ext is the original image file extension.   The
              background image is installed into the image before CPACK_DMG_DS_STORE_SETUP_SCRIPT
              is executed or CPACK_DMG_DS_STORE is installed.  By default no background image  is
              set.

       CPACK_DMG_SLA_DIR
              Directory where license and menu files for different languages are stored.  Setting
              this causes CPack to look for a <language>.menu.txt and <language>.license.txt file
              for  every  language  defined in CPACK_DMG_SLA_LANGUAGES. If both this variable and
              CPACK_RESOURCE_FILE_LICENSE are set, CPack will only look for the  menu  files  and
              use the same license file for all languages.

       CPACK_DMG_SLA_LANGUAGES
              Languages  for  which  a  license agreement is provided when mounting the generated
              DMG. A menu file consists of 9 lines of text. The first line is is the name of  the
              language  itself,  uppercase,  in  English  (e.g.  German).   The  other  lines are
              translations of the following strings:

              • Agree

              • Disagree

              • Print

              • Save...

              • You agree to the terms of the  License  Agreement  when  you  click  the  "Agree"
                button.

              • Software License Agreement

              • This  text  cannot  be  saved. The disk may be full or locked, or the file may be
                locked.

              • Unable to print. Make sure you have selected a printer.

              For every language in this list, CPack will try to find  files  <language>.menu.txt
              and  <language>.license.txt  in  the  directory  specified by the CPACK_DMG_SLA_DIR
              variable.

       CPACK_COMMAND_HDIUTIL
              Path to the hdiutil(1) command used to operate on disk image files  on  Mac  OS  X.
              This  variable  can  be  used  to  override  the automatically detected command (or
              specify its location if the auto-detection fails to find it.)

       CPACK_COMMAND_SETFILE
              Path to the SetFile(1) command  used  to  set  extended  attributes  on  files  and
              directories  on  Mac  OS X. This variable can be used to override the automatically
              detected command (or specify its location if the auto-detection fails to find it.)

       CPACK_COMMAND_REZ
              Path to the Rez(1) command used to compile resources on Mac OS X. This variable can
              be  used to override the automatically detected command (or specify its location if
              the auto-detection fails to find it.)

   CPackIFW
       This module looks for the location of the command line  utilities  supplied  with  the  Qt
       Installer Framework (QtIFW).

       The  module  also  defines  several  commands  to  control  the  behavior of the CPack IFW
       generator.

   Overview
       CPack IFW  generator  helps  you  to  create  online  and  offline  binary  cross-platform
       installers with a graphical user interface.

       CPack  IFW  generator  prepares  project installation and generates configuration and meta
       information for QtIFW tools.

       The QtIFW provides a set of tools and utilities to create  installers  for  the  supported
       desktop Qt platforms: Linux, Microsoft Windows, and Mac OS X.

              DISPLAY_NAME "MyBigPlugin"
              DESCRIPTION "My Big Downloadable Plugin"
              DOWNLOADED)
          cpack_ifw_add_repository(myrepo
              URL "http://example.com/ifw/repo/myapp"
              DISPLAY_NAME "My Application Repository")

   Online installer
       By default CPack IFW generator makes offline installer. This  means  that  all  components
       will be packaged into a binary file.

       To   make   a   component   downloaded,   you   must   set   the   DOWNLOADED   option  in
       cpack_add_component().

       Then you would use the command cpack_configure_downloads().  If you  set  ALL  option  all
       components will be downloaded.

       You  also  can  use command cpack_ifw_add_repository() and variable CPACK_IFW_DOWNLOAD_ALL
       for more specific configuration.

       CPack IFW generator creates "repository" dir in current binary dir. You would copy content
       of this dir to specified site (url).

       The following variable is specific to installers built on Mac OS X using PackageMaker:

       CPACK_OSX_PACKAGE_VERSION
              The  version  of  Mac  OS  X  that  the  resulting  PackageMaker  archive should be
              compatible with. Different versions of Mac OS X  support  different  features.  For
              example,  CPack  can  only  build  component-based  installers for Mac OS X 10.4 or
              newer, and can only build installers that download component son-the-fly for Mac OS
              X  10.5  or  newer. If left blank, this value will be set to the minimum version of
              Mac OS X that supports the requested features. Set  this  variable  to  some  value
              (e.g.,  10.4)  only  if you want to guarantee that your installer will work on that
              version of Mac OS X, and  don't  mind  missing  extra  features  available  in  the
              installer shipping with later versions of Mac OS X.

   CPackRPM
       The builtin (binary) CPack RPM generator (Unix only)

   Variables specific to CPack RPM generator
       CPackRPM  may  be  used  to create RPM package using CPack.  CPackRPM is a CPack generator
       thus     it     uses     the     CPACK_XXX     variables     used     by      CPack      :
       https://cmake.org/Wiki/CMake:CPackConfiguration

       However CPackRPM has specific features which are controlled by the specifics CPACK_RPM_XXX
       variables.  CPackRPM is a component aware generator so when CPACK_RPM_COMPONENT_INSTALL is
       ON  some  more  CPACK_RPM_<ComponentName>_XXXX  variables  may  be  used  in order to have
       component specific values.  Note however that <componentName> refers to the grouping name.
       This  may  be  either  a  component  name  or  a component GROUP name.  Usually those vars
       correspond to RPM spec file entities, one may  find  information  about  spec  files  here
       http://www.rpm.org/wiki/Docs.  You'll find a detailed usage of CPackRPM on the wiki:

          https://cmake.org/Wiki/CMake:CPackPackageGenerators#RPM_.28Unix_Only.29

       However as a handy reminder here comes the list of specific variables:

       CPACK_RPM_PACKAGE_SUMMARY

              • Mandatory : YES

              • Default   : 1

              This  is the numbering of the RPM package itself, i.e. the version of the packaging
              and not the version of the content (see CPACK_RPM_PACKAGE_VERSION). One may  change
              the default value if the previous packaging was buggy and/or you want to put here a
              fancy Linux distro specific numbering.

       CPACK_RPM_PACKAGE_RELOCATABLE
              build a relocatable RPM.

              • Mandatory : NO

              • Default   : CPACK_PACKAGE_RELOCATABLE

              If  this variable is set to TRUE or ON CPackRPM will try to build a relocatable RPM
              package. A relocatable RPM may be installed using:

                 rpm --prefix or --relocate

              in order to install it at an alternate place see rpm(8).  Note that currently  this
              may  fail  if CPACK_SET_DESTDIR is set to ON.  If CPACK_SET_DESTDIR is set then you
              will get a warning message but if there is file installed with absolute path you'll
              get unexpected behavior.

       CPACK_RPM_SPEC_INSTALL_POST

              • Mandatory : NO

              • Default   : -

              • Deprecated: YES

              This    way    of    specifying    post-install    script    is   deprecated,   use
              CPACK_RPM_POST_INSTALL_SCRIPT_FILE.  May be used to set an RPM post-install command
              inside the spec file.  For example setting it to "/bin/true" may be used to prevent
              rpmbuild to strip binaries.

       CPACK_RPM_SPEC_MORE_DEFINE
              RPM extended spec definitions lines.

              • Mandatory : NO

              • Default   : -

              May be used to add any %define lines to the generated spec file.

       CPACK_RPM_PACKAGE_DEBUG
              Toggle CPackRPM debug output.

              • Mandatory : NO

              • Default   : -

              May be set when invoking cpack in order to trace debug information during CPack RPM
              run. For example you may launch CPack like this:

                 cpack -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM

       CPACK_RPM_USER_BINARY_SPECFILE
              A user provided spec file.

              • Mandatory : NO

              • Default   : -

              May  be  set  by the user in order to specify a USER binary spec file to be used by
              CPackRPM instead of generating the file.  The specified file will be  processed  by
              configure_file(  @ONLY).   One  can  provide  a  component specific file by setting
              CPACK_RPM_<componentName>_USER_BINARY_SPECFILE.

       CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE
              Spec file template.

              • Mandatory : NO

              • Default   : -

              If set CPack will generate a template for USER specified binary spec file and  stop
              with an error. For example launch CPack like this:

                 cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM

              The  user  may  then  use  this file in order to hand-craft is own binary spec file
              which may be used with CPACK_RPM_USER_BINARY_SPECFILE.

       CPACK_RPM_PRE_INSTALL_SCRIPT_FILE

       CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE

              • Mandatory : NO

              • Default   : -

              May be used to embed a pre (un)installation script in the spec file.   The  refered
              script  file(s)  will  be read and directly put after the %pre or %preun section If
              CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for each  component
              can    be   overridden   with   CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE   and
              CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE.  One may  verify  which  scriptlet
              has been included with:

                 rpm -qp --scripts  package.rpm

       CPACK_RPM_POST_INSTALL_SCRIPT_FILE

       CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE

              • Mandatory : NO

              • Default   : -

              May  be used to embed a post (un)installation script in the spec file.  The refered
              script file(s) will be read and directly put after the %post  or  %postun  section.
              If  CPACK_RPM_COMPONENT_INSTALL  is  set  to  ON  the  (un)install  script for each
              component can be overridden with CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE and
              CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE.   One  may verify which scriptlet
              has been included with:

                 rpm -qp --scripts  package.rpm

       CPACK_RPM_USER_FILELIST

       CPACK_RPM_<COMPONENT>_USER_FILELIST

              • Mandatory : NO

              • Default   : -

              May be used to explicitly specify %(<directive>) file line in the spec  file.  Like
              %config(noreplace)  or  any  other  directive  that be found in the %files section.
              Since CPackRPM is generating the list of files (and directories) the user specified
              files  of  the  CPACK_RPM_<COMPONENT>_USER_FILELIST  list  will be removed from the
              generated list.

       CPACK_RPM_CHANGELOG_FILE
              RPM changelog file.

              • Mandatory : NO

              • Default   : -

              May be used to embed a changelog in the spec file.  The refered file will  be  read
              and directly put after the %changelog section.

       CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST
              list of path to be excluded.

              • Mandatory : NO

              • Default    :  /etc  /etc/init.d  /usr /usr/share /usr/share/doc /usr/bin /usr/lib
                /usr/lib64 /usr/include

              May be used to exclude path (directories or files) from the auto-generated list  of
              paths discovered by CPack RPM. The defaut value contains a reasonable set of values
              if the variable is not defined by the user. If the variable is defined by the  user
              then  CPackRPM  will  NOT any of the default path.  If you want to add some path to
              the default list then  you  can  use  CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION
              variable.

       CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION
              additional list of path to be excluded.

              • Mandatory : NO

              • Default   : -

              May  be  used  to  add  more  exclude  path (directories or files) from the initial
              default list of excluded paths. See CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST.

       CPACK_RPM_RELOCATION_PATHS

              • Mandatory : NO

              • Default   : -

              May be used to specify more than one relocation path per relocatable RPM.  Variable
              contains  a  list of relocation paths that if relative are prefixed by the value of
              CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX      or      by       the       value       of
              CPACK_PACKAGING_INSTALL_PREFIX  if the component version is not provided.  Variable
              is not component based as its content can be used to set a  different  path  prefix
              for e.g. binary dir and documentation dir at the same time.  Only prefixes that are
              required by a certain component are  added  to  that  component  -  component  must
              contain  at  least one file/directory/symbolic link with CPACK_RPM_RELOCATION_PATHS
              prefix for a certain relocation path to be added.  Package  will  not  contain  any
              relocation  paths  if  there  are no files/directories/symbolic links on any of the
              provided prefix locations.  Packages that either  do  not  contain  any  relocation
              paths or contain files/directories/symbolic links that are outside relocation paths
              print out an AUTHOR_WARNING that RPM will be partially relocatable.

       CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX

              • Mandatory : NO

              • Default   : CPACK_PACKAGING_INSTALL_PREFIX

              May be used to set per component CPACK_PACKAGING_INSTALL_PREFIX for relocatable RPM
              packages.

       CPACK_RPM_NO_INSTALL_PREFIX_RELOCATION

       CPACK_RPM_NO_<COMPONENT>_INSTALL_PREFIX_RELOCATION

              • Mandatory : NO

              •

                Default
                       CPACK_PACKAGING_INSTALL_PREFIX or CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX are
                       treated as one of relocation paths

              May     be     used     to      remove      CPACK_PACKAGING_INSTALL_PREFIX      and
              CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX from relocatable RPM prefix paths.

       CPACK_RPM_ADDITIONAL_MAN_DIRS

              • Mandatory : NO

              • Default   : -

              May  be  used  to  set  additional man dirs that could potentially be compressed by
              brp-compress RPM macro. Variable content must be a list of regular expressions that
              point  to  directories  containing man files or to man files directly. Note that in
              order to compress man pages a path must also be present in brp-compress RPM  script
              and  that  brp-compress  script must be added to RPM configuration by the operating
              system.

              Regular expressions that are added by default  were  taken  from  brp-compress  RPM
              macro:

              • /usr/man/man.*

              • /usr/man/.*/man.*

              • /usr/info.*

              • /usr/share/man/man.*

              • /usr/share/man/.*/man.*

              • /usr/share/info.*

              • /usr/kerberos/man.*

              • /usr/X11R6/man/man.*

              • /usr/lib/perl5/man/man.*

              • /usr/share/doc/.*/man/man.*

              • /usr/lib/.*/man/man.*

   Packaging of Symbolic Links
       CPackRPM supports packaging of symbolic links:

          execute_process(COMMAND ${CMAKE_COMMAND}
            -E create_symlink <relative_path_location> <symlink_name>)
          install(FILES ${CMAKE_CURRENT_BINARY_DIR}/<symlink_name>
            DESTINATION <symlink_location> COMPONENT libraries)

       Symbolic  links will be optimized (paths will be shortened if possible) before being added
       to the package or if multiple relocation  paths  are  detected,  a  post  install  symlink
       relocation script will be generated.

       Symbolic  links may point to locations that are not packaged by the same package (either a
       different component or even not packaged at all) but those locations will be treated as if
       they  were  a part of the package while determining if symlink should be either created or
       present in a post install script - depending on relocation paths.

       Currenty there are a few limitations though:

       • Only symbolic links with relative path can be packaged.

       • For component based packaging component interdependency is not checked  when  processing
         symbolic  links. Symbolic links pointing to content of a different component are treated
         the same way as if pointing to location that will not be packaged.

       • Symbolic links pointing to a location through one or more  intermediate  symbolic  links
         will  not  be  handled  differently  - if the intermediate symbolic link(s) is also on a
         relocatable path, relocating it during package installation may cause  initial  symbolic
         link to point to an invalid location.

   CPack
       Build binary and source package installers.

   Variables common to all CPack generators
       The  CPack module generates binary and source installers in a variety of formats using the
       cpack program.  Inclusion of the CPack module  adds  two  new  targets  to  the  resulting
       makefiles,  package  and  package_source,  which  build  the binary and source installers,
       respectively.  The generated binary installers contain everything  installed  via  CMake's
       INSTALL  command  (and the deprecated INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS
       commands).

       For certain kinds of binary installers (including the graphical installers on Mac OS X and
       Windows),  CPack  generates  installers  that allow users to select individual application
       components to install.  See CPackComponent module for that.

       The CPACK_GENERATOR variable has  different  meanings  in  different  contexts.   In  your
       CMakeLists.txt  file,  CPACK_GENERATOR  is  a  list  of generators: when run with no other
       arguments, CPack will iterate over that list and produce one package for  each  generator.
       In  a  CPACK_PROJECT_CONFIG_FILE,  though,  CPACK_GENERATOR  is  a  string naming a single
       generator.  If you need per-cpack- generator logic to control other cpack  settings,  then
       you need a CPACK_PROJECT_CONFIG_FILE.

       The CMake source tree itself contains a CPACK_PROJECT_CONFIG_FILE.  See the top level file
       CMakeCPackOptions.cmake.in for an example.

       If set, the CPACK_PROJECT_CONFIG_FILE is included automatically on a per-generator  basis.
       It only need contain overrides.

       Here's how it works:

       • cpack runs

       • it includes CPackConfig.cmake

       • it  iterates  over  the  generators  listed in that file's CPACK_GENERATOR list variable
         (unless told to use just a specific one via -G on the command line...)

       • foreach generator, it then

         • sets CPACK_GENERATOR to the one currently being iterated

         • includes the CPACK_PROJECT_CONFIG_FILE

         • produces the package for that generator

       This is the key: For each generator listed in CPACK_GENERATOR in CPackConfig.cmake,  cpack
       will reset CPACK_GENERATOR internally to the one currently being used and then include the
       CPACK_PROJECT_CONFIG_FILE.

       Before including this CPack module in your CMakeLists.txt file, there  are  a  variety  of
       variables  that  can be set to customize the resulting installers.  The most commonly-used
       variables are:

       CPACK_PACKAGE_NAME
              The name of the package (or application). If not specified, defaults to the project
              name.

       CPACK_PACKAGE_VENDOR
              The name of the package vendor. (e.g., "Kitware").

       CPACK_PACKAGE_DIRECTORY
              The  directory  in  which  CPack is doing its packaging. If it is not set then this
              will default (internally) to the build dir. This variable may be defined  in  CPack
              config  file  or  from  the cpack command line option "-B". If set the command line
              option override the value found in the config file.

       CPACK_PACKAGE_VERSION_MAJOR
              Package major Version

       CPACK_PACKAGE_VERSION_MINOR
              Package minor Version

       CPACK_PACKAGE_VERSION_PATCH
              Package patch Version

       CPACK_PACKAGE_DESCRIPTION_FILE
              A text file used to describe the  project.  Used,  for  example,  the  introduction
              screen of a CPack-generated Windows installer to describe the project.

       CPACK_PACKAGE_DESCRIPTION_SUMMARY
              Short description of the project (only a few words).

       CPACK_PACKAGE_FILE_NAME
              The name of the package file to generate, not including the extension. For example,
              cmake-2.6.1-Linux-i686.  The default value is:

                 ${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}.

       CPACK_PACKAGE_INSTALL_DIRECTORY
              Installation directory on the target  system.  This  may  be  used  by  some  CPack
              generators  like  NSIS  to create an installation directory e.g., "CMake 2.5" below
              the installation prefix. All installed element will be put inside this directory.

       CPACK_PACKAGE_ICON
              A branding image  that  will  be  displayed  inside  the  installer  (used  by  GUI
              installers).

       CPACK_PROJECT_CONFIG_FILE
              CPack-time project CPack configuration file. This file included at cpack time, once
              per generator after CPack has set CPACK_GENERATOR to  the  actual  generator  being
              used. It allows per-generator setting of CPACK_* variables at cpack time.

       CPACK_RESOURCE_FILE_LICENSE
              License to be embedded in the installer. It will typically be displayed to the user
              by the produced installer (often with an explicit "Accept"  button,  for  graphical
              installers) prior to installation. This license file is NOT added to installed file
              but is used by some CPack generators like NSIS. If you want to  install  a  license
              file  (may  be  the  same  as  this  one)  along  with your project you must add an
              appropriate CMake INSTALL command in your CMakeLists.txt.

       CPACK_RESOURCE_FILE_README
              ReadMe file to be embedded in the installer. It typically describes in some  detail
              the  purpose  of the project during the installation. Not all CPack generators uses
              this file.

       CPACK_RESOURCE_FILE_WELCOME
              Welcome file to be embedded in the installer. It welcomes users to this  installer.
              Typically used in the graphical installers on Windows and Mac OS X.

       CPACK_MONOLITHIC_INSTALL
              Disables  the  component-based  installation  mechanism.  When  set  the  component
              specification is ignored and all installed items are put in a  single  "MONOLITHIC"
              package.  Some CPack generators do monolithic packaging by default and may be asked
              to do component packaging by setting CPACK_<GENNAME>_COMPONENT_INSTALL to 1/TRUE.

       CPACK_GENERATOR
              List of CPack generators to use. If not specified,  CPack  will  create  a  set  of
              options  CPACK_BINARY_<GENNAME>  (e.g.,  CPACK_BINARY_NSIS)  allowing  the  user to
              enable/disable individual generators. This variable may be used on the command line
              as well as in:

                 cpack -D CPACK_GENERATOR="ZIP;TGZ" /path/to/build/tree

       CPACK_OUTPUT_CONFIG_FILE
              The  name  of  the  CPack  binary  configuration  file.  This  file  is  the  CPack
              configuration generated by the CPack module  for  binary  installers.  Defaults  to
              CPackConfig.cmake.

       CPACK_PACKAGE_EXECUTABLES
              Lists  each of the executables and associated text label to be used to create Start
              Menu shortcuts. For example, setting this to the list ccmake;CMake  will  create  a
              shortcut  named  "CMake" that will execute the installed executable ccmake. Not all
              CPack generators use it (at least NSIS, WIX and OSXX11 do).

       CPACK_STRIP_FILES
              List of files to be stripped. Starting with CMake 2.6.0 CPACK_STRIP_FILES will be a
              boolean variable which enables stripping of all files (a list of files evaluates to
              TRUE in CMake, so this change is compatible).

       CPACK_VERBATIM_VARIABLES
              If set to TRUE, values of variables prefixed with  CPACK  will  be  escaped  before
              being  written  to the configuration files, so that the cpack program receives them
              exactly as they were specified. If not, characters like quotes and backslashes  can
              cause  parsing errors or alter the value received by the cpack program. Defaults to
              FALSE for backwards compatibility.

              • Mandatory : NO

              • Default   : FALSE

       The following CPack variables are specific to source packages, and will not affect  binary
       packages:

       CPACK_SOURCE_PACKAGE_FILE_NAME
              The name of the source package. For example cmake-2.6.1.

       CPACK_SOURCE_STRIP_FILES
              List  of  files in the source tree that will be stripped. Starting with CMake 2.6.0
              CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables stripping of  all
              files (a list of files evaluates to TRUE in CMake, so this change is compatible).

       CPACK_SOURCE_GENERATOR
              List  of  generators used for the source packages. As with CPACK_GENERATOR, if this
              is not specified then CPack will create a set of options  (e.g.,  CPACK_SOURCE_ZIP)
              allowing users to select which packages will be generated.

       CPACK_SOURCE_OUTPUT_CONFIG_FILE
              The  name  of  the  CPack  source  configuration  file.  This  file  is  the  CPack
              configuration generated by the CPack module  for  source  installers.  Defaults  to
              CPackSourceConfig.cmake.

       CPACK_SOURCE_IGNORE_FILES
              Pattern  of  files in the source tree that won't be packaged when building a source
              package. This is a list of regular  expression  patterns  (that  must  be  properly
              escaped), e.g., /CVS/;/\.svn/;\.swp$;\.#;/#;.*~;cscope.*

       The following variables are for advanced uses of CPack:

       CPACK_CMAKE_GENERATOR
              What  CMake  generator  should be used if the project is CMake project. Defaults to
              the value of CMAKE_GENERATOR few users will want to change this setting.

       CPACK_INSTALL_CMAKE_PROJECTS
              List of four values that specify what project to  install.  The  four  values  are:
              Build directory, Project Name, Project Component, Directory. If omitted, CPack will
              build an installer that installs everything.

       CPACK_SYSTEM_NAME
              System name, defaults to the value of ${CMAKE_SYSTEM_NAME}.

       CPACK_PACKAGE_VERSION
              Package  full  version,  used  internally.  By  default,   this   is   built   from
              CPACK_PACKAGE_VERSION_MAJOR,            CPACK_PACKAGE_VERSION_MINOR,            and
              CPACK_PACKAGE_VERSION_PATCH.

       CPACK_TOPLEVEL_TAG
              Directory for the installed files.

       CPACK_INSTALL_COMMANDS
              Extra commands to install components.

       CPACK_INSTALLED_DIRECTORIES
              Extra directories to install.

       CPACK_PACKAGE_INSTALL_REGISTRY_KEY
              Registry key used when installing this project. This is only used by installer  for
              Windows.  The default value is based on the installation directory.

       CPACK_CREATE_DESKTOP_LINKS
              List  of desktop links to create.  Each desktop link requires a corresponding start
              menu shortcut as created by CPACK_PACKAGE_EXECUTABLES.

       CPACK_BINARY_<GENNAME>
              CPack generated options for binary generators.  The  CPack.cmake  module  generates
              (when CPACK_GENERATOR is not set) a set of CMake options (see CMake option command)
              which may then be used to select the CPack generator(s) to be used  when  launching
              the package target.

              Provide  options to choose generators we might check here if the required tools for
              the generates exist and set the defaults according to the results

   CPackWIX
       CPack WiX generator specific options

   Variables specific to CPack WiX generator
       The following variables are specific to the installers built on Windows using WiX.

       CPACK_WIX_UPGRADE_GUID
              Upgrade GUID (Product/@UpgradeCode)

              Will be automatically generated unless explicitly provided.

              It should be explicitly set to a  constant  generated  globally  unique  identifier
              (GUID) to allow your installers to replace existing installations that use the same
              GUID.

              You may for example explicitly set this variable  in  your  CMakeLists.txt  to  the
              value  that  has been generated per default.  You should not use GUIDs that you did
              not generate yourself or which may belong to other projects.

              A GUID shall have the following fixed length syntax:

                 XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

              (each X represents an uppercase hexadecimal digit)

       CPACK_WIX_PRODUCT_GUID
              Product GUID (Product/@Id)

              Will be automatically generated unless explicitly provided.

              If explicitly provided this will set the Product Id of your installer.

              The installer will abort if it detects a pre-existing installation  that  uses  the
              same GUID.

              The GUID shall use the syntax described for CPACK_WIX_UPGRADE_GUID.

       CPACK_WIX_LICENSE_RTF
              RTF License File

              If CPACK_RESOURCE_FILE_LICENSE has an .rtf extension it is used as-is.

              If  CPACK_RESOURCE_FILE_LICENSE has an .txt extension it is implicitly converted to
              RTF by the WiX Generator.  The expected encoding of the .txt file is UTF-8.

              With CPACK_WIX_LICENSE_RTF you can override  the  license  file  used  by  the  WiX
              Generator  in  case  CPACK_RESOURCE_FILE_LICENSE is in an unsupported format or the
              .txt -> .rtf conversion does not work as expected.

       CPACK_WIX_PRODUCT_ICON
              The Icon shown next to the program name in Add/Remove programs.

              If set, this icon is used in place of the default icon.

       CPACK_WIX_UI_REF
              This variable allows you to override the Id of  the  <UIRef>  element  in  the  WiX
              template.

              The  default  is WixUI_InstallDir in case no CPack components have been defined and
              WixUI_FeatureTree otherwise.

       CPACK_WIX_UI_BANNER
              The bitmap will appear at the top of all installer pages other than the welcome and
              completion dialogs.

              If set, this image will replace the default banner image.

              This image must be 493 by 58 pixels.

       CPACK_WIX_UI_DIALOG
              Background bitmap used on the welcome and completion dialogs.

              If this variable is set, the installer will replace the default dialog image.

              This image must be 493 by 312 pixels.

       CPACK_WIX_PROGRAM_MENU_FOLDER
              Start menu folder name for launcher.

              If this variable is not set, it will be initialized with CPACK_PACKAGE_NAME

       CPACK_WIX_CULTURES
              Language(s) of the installer

              Languages  are  compiled  into  the  WixUI  extension library.  To use them, simply
              provide the name of the culture.  If you specify more than one  culture  identifier
              in  a  comma or semicolon delimited list, the first one that is found will be used.
              You     can     find     a      list      of      supported      languages      at:
              http://wix.sourceforge.net/manual-wix3/WixUI_localization.htm

       CPACK_WIX_TEMPLATE
              Template file for WiX generation

              If  this  variable  is set, the specified template will be used to generate the WiX
              wxs file.  This should be used if further customization of the output is required.

              If this variable is not set, the default MSI template included with CMake  will  be
              used.

       CPACK_WIX_PATCH_FILE
              Optional list of XML files with fragments to be inserted into generated WiX sources

              This  optional  variable  can be used to specify an XML file that the WiX generator
              will use to inject fragments into its generated source files.

              Patch files understood by the CPack WiX generator  roughly  follow  this  RELAX  NG
              compact schema:

                 start = CPackWiXPatch

                 CPackWiXPatch = element CPackWiXPatch { CPackWiXFragment* }

                 CPackWiXFragment = element CPackWiXFragment
                 {
                     attribute Id { string },
                     fragmentContent*
                 }

                 fragmentContent = element * - CPackWiXFragment
                 {
                     (attribute * { text } | text | fragmentContent)*
                 }

              Currently  fragments  can  be  injected  into  most  Component,  File and Directory
              elements.

              The following additional special Ids can be used:

              • #PRODUCT for the <Product> element.

              • #PRODUCTFEATURE for the root <Feature> element.

              The following example illustrates how this works.

              Given that the WiX generator creates the following XML element:

                 <Component Id="CM_CP_applications.bin.my_libapp.exe" Guid="*"/>

              The following XML patch file may be used to inject an Environment element into it:

                 <CPackWiXPatch>
                   <CPackWiXFragment Id="CM_CP_applications.bin.my_libapp.exe">
                     <Environment Id="MyEnvironment" Action="set"
                       Name="MyVariableName" Value="MyVariableValue"/>
                   </CPackWiXFragment>
                 </CPackWiXPatch>

       CPACK_WIX_EXTRA_SOURCES
              Extra WiX source files

              This variable provides an optional list of  extra  WiX  source  files  (.wxs)  that
              should be compiled and linked.  The full path to source files is required.

       CPACK_WIX_EXTRA_OBJECTS
              Extra WiX object files or libraries

              This  variable  provides  an optional list of extra WiX object (.wixobj) and/or WiX
              library (.wixlib) files.  The full path to objects and libraries is required.

       CPACK_WIX_EXTENSIONS
              This variable provides a list of additional extensions for the WiX tools light  and
              candle.

       CPACK_WIX_<TOOL>_EXTENSIONS
              This  is  the  tool specific version of CPACK_WIX_EXTENSIONS.  <TOOL> can be either
              LIGHT or CANDLE.

       CPACK_WIX_<TOOL>_EXTRA_FLAGS
              This list variable allows you to pass additional flags to the WiX tool <TOOL>.

              Use it at your own risk.  Future versions of CPack may generate flags which may  be
              in conflict with your own flags.

              <TOOL> can be either LIGHT or CANDLE.

       CPACK_WIX_CMAKE_PACKAGE_REGISTRY
              If this variable is set the generated installer will create an entry in the windows
              registry key HKEY_LOCAL_MACHINE\Software\Kitware\CMake\Packages\<package> The value
              for <package> is provided by this variable.

              Assuming  you  also  install a CMake configuration file this will allow other CMake
              projects to find your package with the find_package() command.

       CPACK_WIX_PROPERTY_<PROPERTY>
              This variable can be used to provide a value for  the  Windows  Installer  property
              <PROPERTY>

              The  following  list contains some example properties that can be used to customize
              information under "Programs and Features" (also known as "Add or Remove Programs")

              • ARPCOMMENTS - Comments

              • ARPHELPLINK - Help and support information URL

              • ARPURLINFOABOUT - General information URL

              • URLUPDATEINFO - Update information URL

              • ARPHELPTELEPHONE - Help and support telephone number

              • ARPSIZE - Size (in kilobytes) of the application

   CTest
       Configure a project for testing with CTest/CDash

       Include this module in the top CMakeLists.txt file of a project  to  enable  testing  with
       CTest and dashboard submissions to CDash:

          project(MyProject)
          ...
          include(CTest)

       The  module  automatically  creates  a BUILD_TESTING option that selects whether to enable
       testing support (ON by default).  After including the module, use code like:

          if(BUILD_TESTING)
            # ... CMake code to create tests ...
          endif()

       to creating tests when testing is enabled.

       To enable submissions to a CDash server, create a CTestConfig.cmake file at the top of the
       project with content such as:

          set(CTEST_PROJECT_NAME "MyProject")
          set(CTEST_NIGHTLY_START_TIME "01:00:00 UTC")
          set(CTEST_DROP_METHOD "http")
          set(CTEST_DROP_SITE "my.cdash.org")
          set(CTEST_DROP_LOCATION "/submit.php?project=MyProject")
          set(CTEST_DROP_SITE_CDASH TRUE)

       (the  CDash  server  can  provide  the  file  to  a  project  administrator who configures
       MyProject).  Settings in the config file are shared by both  this  CTest  module  and  the
       ctest(1) command-line Dashboard Client mode (ctest -S).

       While  building a project for submission to CDash, CTest scans the build output for errors
       and warnings and reports them with surrounding context from the build log.   This  generic
       approach works for all build tools, but does not give details about the command invocation
       that produced a given  problem.   One  may  get  more  detailed  reports  by  setting  the
       CTEST_USE_LAUNCHERS variable:

          set(CTEST_USE_LAUNCHERS 1)

       in the CTestConfig.cmake file.

   CTestCoverageCollectGCOV
       This module provides the function ctest_coverage_collect_gcov.  The function will run gcov
       on the .gcda files in a binary tree and then package all of the .gcov  files  into  a  tar
       file  with  a data.json that contains the source and build directories for CDash to use in
       parsing the coverage data. In addtion the Labels.json files for targets that have coverage
       information  are also put in the tar file for CDash to asign the correct labels. This file
       can be sent to a CDash server for display with the ctest_submit(CDASH_UPLOAD) command.

       cdash_coverage_collect_gcov

                 ctest_coverage_collect_gcov(TARBALL <tarfile>
                   [SOURCE <source_dir>][BUILD <build_dir>]
                   [GCOV_COMMAND <gcov_command>]
                   [GCOV_OPTIONS <options>...]
                   )

              Run gcov and package a tar file for CDash.  The options are:

              TARBALL <tarfile>
                     Specify the location of the .tar file to be  created  for  later  upload  to
                     CDash.   Relative  paths  will  be interpreted with respect to the top-level
                     build directory.

              SOURCE <source_dir>
                     Specify the top-level source directory for the build.  Default is the  value
                     of CTEST_SOURCE_DIRECTORY.

              BUILD <build_dir>
                     Specify  the  top-level build directory for the build.  Default is the value
                     of CTEST_BINARY_DIRECTORY.

              GCOV_COMMAND <gcov_command>
                     Specify the full path to the gcov command on the machine.   Default  is  the
                     value of CTEST_COVERAGE_COMMAND.

              GCOV_OPTIONS <options>...
                     Specify  options  to  be  passed  to  gcov.  The gcov command is run as gcov
                     <options>... -o <gcov-dir>  <file>.gcda.   If  not  specified,  the  default
                     option is just -b.

              QUIET  Suppress  non-error  messages  that otherwise would have been printed out by
                     this function.

   CTestScriptMode
       This file is read by ctest in script mode (-S)

   CTestUseLaunchers
       Set the RULE_LAUNCH_* global properties when CTEST_USE_LAUNCHERS is on.

       CTestUseLaunchers is automatically included when you include(CTest).  However, it is split
       out  into  its  own  module file so projects can use the CTEST_USE_LAUNCHERS functionality
       independently.

       To use launchers, set CTEST_USE_LAUNCHERS to ON in a ctest -S dashboard script,  and  then
       also set it in the cache of the configured project.  Both cmake and ctest need to know the
       value of it for the launchers to work properly.  CMake needs to know in order to  generate
       proper build rules, and ctest, in order to produce the proper error and warning analysis.

       For convenience, you may set the ENV variable CTEST_USE_LAUNCHERS_DEFAULT in your ctest -S
       script,   too.    Then,   as   long   as   your   CMakeLists   uses   include(CTest)    or
       include(CTestUseLaunchers),  it  will  use  the  value of the ENV variable to initialize a
       CTEST_USE_LAUNCHERS cache variable.  This cache variable  initialization  only  occurs  if
       CTEST_USE_LAUNCHERS is not already defined.

   Dart
       Configure a project for testing with CTest or old Dart Tcl Client

       This  file  is the backwards-compatibility version of the CTest module.  It supports using
       the old Dart 1 Tcl client for driving dashboard submissions as well as testing with CTest.
       This  module  should  be  included  in  the  CMakeLists.txt  file at the top of a project.
       Typical usage:

          include(Dart)
          if(BUILD_TESTING)
            # ... testing related CMake code ...
          endif()

       The BUILD_TESTING option is created by  the  Dart  module  to  determine  whether  testing
       support should be enabled.  The default is ON.

   DeployQt4
       Functions to help assemble a standalone Qt4 executable.

       A collection of CMake utility functions useful for deploying Qt4 executables.

       The following functions are provided by this module:

          write_qt4_conf
          resolve_qt4_paths
          fixup_qt4_executable
          install_qt4_plugin_path
          install_qt4_plugin
          install_qt4_executable

       Requires  CMake 2.6 or greater because it uses function and PARENT_SCOPE.  Also depends on
       BundleUtilities.cmake.

          WRITE_QT4_CONF(<qt_conf_dir> <qt_conf_contents>)

       Writes a qt.conf file with the <qt_conf_contents> into <qt_conf_dir>.

          RESOLVE_QT4_PATHS(<paths_var> [<executable_path>])

       Loop through <paths_var> list and  if  any  don't  exist  resolve  them  relative  to  the
       <executable_path> (if supplied) or the CMAKE_INSTALL_PREFIX.

          FIXUP_QT4_EXECUTABLE(<executable>
            [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf>])

       Copies  Qt  plugins,  writes  a  Qt  configuration  file  (if  needed)  and fixes up a Qt4
       executable using BundleUtilities so it is standalone and can be  drag-and-drop  copied  to
       another machine as long as all of the system libraries are compatible.

       <executable> should point to the executable to be fixed-up.

       <qtplugins> should contain a list of the names or paths of any Qt plugins to be installed.

       <libs>  will  be  passed  to BundleUtilities and should be a list of any already installed
       plugins, libraries or executables to also be fixed-up.

       <dirs> will be passed to BundleUtilities and should contain and directories to be searched
       to find library dependencies.

       <plugins_dir> allows an custom plugins directory to be used.

       <request_qt_conf> will force a qt.conf file to be written even if not needed.

          INSTALL_QT4_PLUGIN_PATH(plugin executable copy installed_plugin_path_var
                                  <plugins_dir> <component> <configurations>)

       Install  (or copy) a resolved <plugin> to the default plugins directory (or <plugins_dir>)
       relative to <executable> and store the result in <installed_plugin_path_var>.

       If <copy> is set to TRUE then the plugins will be copied rather than installed.   This  is
       to allow this module to be used at CMake time rather than install time.

       If <component> is set then anything installed will use this COMPONENT.

          INSTALL_QT4_PLUGIN(plugin executable copy installed_plugin_path_var
                             <plugins_dir> <component>)

       Install   (or   copy)  an  unresolved  <plugin>  to  the  default  plugins  directory  (or
       <plugins_dir>)    relative    to    <executable>    and    store     the     result     in
       <installed_plugin_path_var>.  See documentation of INSTALL_QT4_PLUGIN_PATH.

          INSTALL_QT4_EXECUTABLE(<executable>
            [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf> <component>])

       Installs  Qt  plugins,  writes  a  Qt  configuration  file  (if needed) and fixes up a Qt4
       executable using BundleUtilities so it is standalone and can be  drag-and-drop  copied  to
       another  machine  as  long  as all of the system libraries are compatible.  The executable
       will be fixed-up at install time.  <component> is the COMPONENT used for bundle fixup  and
       plugin installation.  See documentation of FIXUP_QT4_BUNDLE.

   ExternalData
       Manage data files stored outside source tree

   Introduction
       Use this module to unambiguously reference data files stored outside the source  tree  and
       fetch  them  at  build  time  from arbitrary local and remote content-addressed locations.
       Functions provided by this module recognize arguments  with  the  syntax  DATA{<name>}  as
       references  to  external data, replace them with full paths to local copies of those data,
       and create build rules to fetch and update the local copies.

       For example:

          include(ExternalData)
          set(ExternalData_URL_TEMPLATES "file:///local/%(algo)/%(hash)"
                                         "file:////host/share/%(algo)/%(hash)"
                                         "http://data.org/%(algo)/%(hash)")
          ExternalData_Add_Test(MyData
            NAME MyTest
            COMMAND MyExe DATA{MyInput.png}
            )
          ExternalData_Add_Target(MyData)

       When test MyTest runs the DATA{MyInput.png} argument will be replaced by the full path  to
       a  real  instance  of  the  data  file MyInput.png on disk.  If the source tree contains a
       content link such as MyInput.png.md5 then the MyData target creates a real MyInput.png  in
       the build tree.

   Module Functions
       ExternalData_Expand_Arguments
              The  ExternalData_Expand_Arguments  function  evaluates  DATA{}  references  in its
              arguments and constructs a new list of arguments:

                 ExternalData_Expand_Arguments(
                   <target>   # Name of data management target
                   <outVar>   # Output variable
                   [args...]  # Input arguments, DATA{} allowed
                   )

              It replaces each DATA{} reference in an argument with the full path of a real  data
              file on disk that will exist after the <target> builds.

       ExternalData_Add_Test
              The  ExternalData_Add_Test  function  wraps around the CMake add_test() command but
              supports DATA{} references in its arguments:

                 ExternalData_Add_Test(
                   <target>   # Name of data management target
                   ...        # Arguments of add_test(), DATA{} allowed
                   )

              It passes its arguments through ExternalData_Expand_Arguments and then invokes  the
              add_test() command using the results.

       ExternalData_Add_Target
              The  ExternalData_Add_Target  function  creates  a  custom  target  to manage local
              instances of data files stored externally:

                 ExternalData_Add_Target(
                   <target>   # Name of data management target
                   )

              It creates custom commands in the target as necessary to make data files  available
              for  each DATA{} reference previously evaluated by other functions provided by this
              module.  Data files may be fetched from one of the URL templates specified  in  the
              ExternalData_URL_TEMPLATES  variable,  or  may be found locally in one of the paths
              specified in the ExternalData_OBJECT_STORES variable.

   Module Variables
       The following variables configure behavior.  They should be set before calling any of  the
       functions provided by this module.

       ExternalData_BINARY_ROOT
              The  ExternalData_BINARY_ROOT variable may be set to the directory to hold the real
              data files named by expanded DATA{} references.  The default  is  CMAKE_BINARY_DIR.
              The    directory    layout    will    mirror    that   of   content   links   under
              ExternalData_SOURCE_ROOT.

       ExternalData_CUSTOM_SCRIPT_<key>
              Specify a full path to a .cmake custom fetch script identified by <key> in  entries
              of the ExternalData_URL_TEMPLATES list.  See Custom Fetch Scripts.

       ExternalData_LINK_CONTENT
              The  ExternalData_LINK_CONTENT  variable may be set to the name of a supported hash
              algorithm to enable automatic conversion of  real  data  files  referenced  by  the
              DATA{}  syntax  into  content  links.   For  each  such <file> a content link named
              <file><ext>  is  created.    The   original   file   is   renamed   to   the   form
              .ExternalData_<algo>_<hash>  to  stage  it  for  future  transmission to one of the
              locations in the list of URL templates (by means outside the scope of this module).
              The  data  fetch rule created for the content link will use the staged object if it
              cannot be found using any URL template.

       ExternalData_NO_SYMLINKS
              The real data files named by expanded DATA{} references may be made available under
              ExternalData_BINARY_ROOT   using   symbolic   links   on   some   platforms.    The
              ExternalData_NO_SYMLINKS variable may be set to disable use of symbolic  links  and
              enable use of copies instead.

       ExternalData_OBJECT_STORES
              The  ExternalData_OBJECT_STORES  variable may be set to a list of local directories
              that store objects using the layout <dir>/%(algo)/%(hash).  These directories  will
              be searched first for a needed object.  If the object is not available in any store
              then it will be fetched remotely using the URL templates and  added  to  the  first
              local  store  listed.   If no stores are specified the default is a location inside
              the build tree.

       ExternalData_SERIES_PARSE

       ExternalData_SERIES_PARSE_PREFIX

       ExternalData_SERIES_PARSE_NUMBER

       ExternalData_SERIES_PARSE_SUFFIX

       ExternalData_SERIES_MATCH
              See Referencing File Series.

       ExternalData_SOURCE_ROOT
              The ExternalData_SOURCE_ROOT variable may be set to the  highest  source  directory
              containing  any path named by a DATA{} reference.  The default is CMAKE_SOURCE_DIR.
              ExternalData_SOURCE_ROOT and CMAKE_SOURCE_DIR must refer to  directories  within  a
              single source distribution (e.g.  they come together in one tarball).

       ExternalData_TIMEOUT_ABSOLUTE
              The  ExternalData_TIMEOUT_ABSOLUTE  variable sets the download absolute timeout, in
              seconds, with a default of 300 seconds.  Set to 0 to disable enforcement.

       ExternalData_TIMEOUT_INACTIVITY
              The ExternalData_TIMEOUT_INACTIVITY variable sets the download inactivity  timeout,
              in seconds, with a default of 60 seconds.  Set to 0 to disable enforcement.

       ExternalData_URL_ALGO_<algo>_<key>
              Specify  a  custom URL component to be substituted for URL template placeholders of
              the form %(algo:<key>), where <key> is a  valid  C  identifier,  when  fetching  an
              object  referenced  via  hash  algorithm  <algo>.   If not defined, the default URL
              component is just <algo> for any <key>.

       ExternalData_URL_TEMPLATES
              The ExternalData_URL_TEMPLATES may be set to provide a list  of  of  URL  templates
              using  the placeholders %(algo) and %(hash) in each template.  Data fetch rules try
              each URL template in order by substituting the hash algorithm name for %(algo)  and
              the  hash  value  for  %(hash).   Alternatively  one  may  use  %(algo:<key>)  with
              ExternalData_URL_ALGO_<algo>_<key> variables to gain  more  flexibility  in  remote
              URLs.

   Referencing Files
   Referencing Single Files
       The  DATA{}  syntax is literal and the <name> is a full or relative path within the source
       tree.  The source tree must contain either a real data file at <name> or a "content  link"
       at  <name><ext> containing a hash of the real file using a hash algorithm corresponding to
       <ext>.  For example, the argument DATA{img.png} may be satisfied by either a real  img.png
       file in the current source directory or a img.png.md5 file containing its MD5 sum.

   Referencing File Series
       The  DATA{} syntax can be told to fetch a file series using the form DATA{<name>,:}, where
       the : is literal.  If the source tree contains a group of files  or  content  links  named
       like  a  series  then a reference to one member adds rules to fetch all of them.  Although
       all members of a series are fetched, only the file originally named by the DATA{} argument
       is substituted for it.  The default configuration recognizes file series names ending with
       #.ext, _#.ext, .#.ext, or -#.ext where # is a sequence of decimal digits and .ext  is  any
       single  extension.  Configure it with a regex that parses <number> and <suffix> parts from
       the end of <name>:

          ExternalData_SERIES_PARSE = regex of the form (<number>)(<suffix>)$

       For more complicated cases set:

          ExternalData_SERIES_PARSE = regex with at least two () groups
          ExternalData_SERIES_PARSE_PREFIX = <prefix> regex group number, if any
          ExternalData_SERIES_PARSE_NUMBER = <number> regex group number
          ExternalData_SERIES_PARSE_SUFFIX = <suffix> regex group number

       Configure series number matching with a regex that matches the  <number>  part  of  series
       members named <prefix><number><suffix>:

          ExternalData_SERIES_MATCH = regex matching <number> in all series members

       Note that the <suffix> of a series does not include a hash-algorithm extension.

   Referencing Associated Files
       The  DATA{}  syntax  can  alternatively  match  files  associated  with the named file and
       contained in the same directory.  Associated files may be specified by options  using  the
       syntax  DATA{<name>,<opt1>,<opt2>,...}.   Each  option  may  specify  one  file by name or
       specify a regular expression to match file names  using  the  syntax  REGEX:<regex>.   For
       example, the arguments:

          DATA{MyData/MyInput.mhd,MyInput.img}                   # File pair
          DATA{MyData/MyFrames00.png,REGEX:MyFrames[0-9]+\\.png} # Series

       will  pass  MyInput.mha  and  MyFrames00.png  on  the  command  line  but  ensure that the
       associated files are present next to them.

   Referencing Directories
       The DATA{} syntax may reference  a  directory  using  a  trailing  slash  and  a  list  of
       associated  files.  The form DATA{<name>/,<opt1>,<opt2>,...} adds rules to fetch any files
       in the directory that match one of the associated file options.  For example, the argument
       DATA{MyDataDir/,REGEX:.*}  will pass the full path to a MyDataDir directory on the command
       line and ensure that the directory contains files corresponding to every file  or  content
       link  in  the  MyDataDir  source  directory.   In  order  to  match  associated  files  in
       subdirectories, specify a RECURSE: option, e.g. DATA{MyDataDir/,RECURSE:,REGEX:.*}.

   Hash Algorithms
       The following hash algorithms are supported:

          %(algo)     <ext>     Description
          -------     -----     -----------
          MD5         .md5      Message-Digest Algorithm 5, RFC 1321
          SHA1        .sha1     US Secure Hash Algorithm 1, RFC 3174
          SHA224      .sha224   US Secure Hash Algorithms, RFC 4634
          SHA256      .sha256   US Secure Hash Algorithms, RFC 4634
          SHA384      .sha384   US Secure Hash Algorithms, RFC 4634
          SHA512      .sha512   US Secure Hash Algorithms, RFC 4634

       Note  that  the  hashes  are  used  only  for  unique  data  identification  and  download
       verification.

   Custom Fetch Scripts
       When  a  data  file  must  be  fetched  from  one  of  the  URL templates specified in the
       ExternalData_URL_TEMPLATES variable, it is normally downloaded  using  the  file(DOWNLOAD)
       command.   One  may  specify usage of a custom fetch script by using a URL template of the
       form ExternalDataCustomScript://<key>/<loc>.  The <key> must be a C  identifier,  and  the
       <loc>  must contain the %(algo) and %(hash) placeholders.  A variable corresponding to the
       key, ExternalData_CUSTOM_SCRIPT_<key>, must be set to the full path  to  a  .cmake  script
       file.   The  script  will  be  included to perform the actual fetch, and provided with the
       following variables:

       ExternalData_CUSTOM_LOCATION
              When a custom fetch script is loaded, this variable is set to the location part  of
              the  URL,  which  will contain the substituted hash algorithm name and content hash
              value.

       ExternalData_CUSTOM_FILE
              When a custom fetch script is loaded, this variable is set to the full  path  to  a
              file  in  which the script must store the fetched content.  The name of the file is
              unspecified and should not be interpreted in any way.

       The custom fetch script is expected to  store  fetched  content  in  the  file  or  set  a
       variable:

       ExternalData_CUSTOM_ERROR
              When  a  custom fetch script fails to fetch the requested content, it must set this
              variable to a short one-line message describing the reason for failure.

   ExternalProject

       ExternalProject_Add
              The ExternalProject_Add  function  creates  a  custom  target  to  drive  download,

              Configure step options are:

              SOURCE_DIR <dir>
                     Source dir to be used for build

              CONFIGURE_COMMAND <cmd>...
                     Build tree configuration command

                     Specify generator for native build

              CMAKE_GENERATOR_PLATFORM <platform>
                     Generator-specific platform name

              CMAKE_GENERATOR_TOOLSET <toolset>
                     Generator-specific toolset name

              CMAKE_ARGS <arg>...
                     Arguments  to  CMake  command  line.   These  arguments  are passed to CMake
                     command line, and can contain arguments other than cache  values,  see  also
                     CMake  Options.  Arguments  in the form -Dvar:string=on are always passed to
                     the command line, and therefore cannot be changed by  the  user.   Arguments
                     may use generator expressions.

              CMAKE_CACHE_ARGS <arg>...
                     Initial  cache  arguments, of the form -Dvar:string=on.  These arguments are
                     written in a pre-load a script that populates CMake cache,  see  also  cmake
                     -C. This allows to overcome command line length limits.  These arguments are
                     set() using the FORCE argument, and therefore cannot be changed by the user.
                     Arguments may use generator expressions.

              CMAKE_CACHE_DEFAULT_ARGS <arg>...
                     Initial  default  cache  arguments,  of  the  form  -Dvar:string=on.   These
                     arguments are written in a pre-load a script that populates CMake cache, see
                     also  cmake  -C.  This allows to overcome command line length limits.  These
                     arguments can be used as default value that will be set if no previous value
                     is  found  in  the cache, and that the user can change later.  Arguments may
                     use generator expressions.

              Build step options are:

              BINARY_DIR <dir>
                     Specify build dir location

              BUILD_COMMAND <cmd>...
                     Command to drive the native build

              BUILD_IN_SOURCE 1
                     Use source dir for build dir

              BUILD_ALWAYS 1
                     No stamp file, build step always runs

              BUILD_BYPRODUCTS <file>...
                     Files that will be generated by the build command but may or  may  not  have
                     their modification time updated by subsequent builds.

              Install step options are:

              INSTALL_DIR <dir>
                     Installation prefix

              INSTALL_COMMAND <cmd>...
                     Command to drive install after build

              Test step options are:

              TEST_BEFORE_INSTALL 1
                     Add test step executed before install step

              TEST_AFTER_INSTALL 1
                     Add test step executed after install step

              TEST_EXCLUDE_FROM_MAIN 1
                     Main target does not depend on the test step

              TEST_COMMAND <cmd>...
                     Command to drive test

              Output logging options are:

              LOG_DOWNLOAD 1
                     Wrap download in script to log output

              LOG_UPDATE 1
                     Wrap update in script to log output

              LOG_CONFIGURE 1
                     Wrap configure in script to log output

              LOG_BUILD 1
                     Wrap build in script to log output

              LOG_TEST 1
                     Wrap test in script to log output

              LOG_INSTALL 1
                     Wrap install in script to log output

              Steps  can  be  given  direct  access  to the terminal if possible.  With the Ninja
              generator, this places the steps in the console pool.  Options are:

              USES_TERMINAL_DOWNLOAD 1
                     Give download terminal access.

              USES_TERMINAL_UPDATE 1
                     Give update terminal access.

              USES_TERMINAL_CONFIGURE 1
                     Give configure terminal access.

              USES_TERMINAL_BUILD 1
                     Give build terminal access.

              USES_TERMINAL_TEST 1
                     Give test terminal access.

              USES_TERMINAL_INSTALL 1
                     Give install terminal access.

              Other options are:

              STEP_TARGETS <step-target>...
                     Generate custom targets for these steps

              INDEPENDENT_STEP_TARGETS <step-target>...
                     Generate custom targets for these steps that do not depend on other external
                     projects even if a dependency is set

              The  *_DIR  options  specify  directories for the project, with default directories
              computed as follows.  If the PREFIX option is given to ExternalProject_Add() or the
              EP_PREFIX  directory  property  is  set,  then  an  external  project  is built and
              installed under the specified prefix:

                 TMP_DIR      = <prefix>/tmp
                 STAMP_DIR    = <prefix>/src/<name>-stamp
                 DOWNLOAD_DIR = <prefix>/src
                 SOURCE_DIR   = <prefix>/src/<name>
                 BINARY_DIR   = <prefix>/src/<name>-build
                 INSTALL_DIR  = <prefix>

              Otherwise, if the EP_BASE directory property is set then components of an  external
              project are stored under the specified base:

                 TMP_DIR      = <base>/tmp/<name>
                 STAMP_DIR    = <base>/Stamp/<name>
                 DOWNLOAD_DIR = <base>/Download/<name>
                 SOURCE_DIR   = <base>/Source/<name>
                 BINARY_DIR   = <base>/Build/<name>
                 INSTALL_DIR  = <base>/Install/<name>

              If  no PREFIX, EP_PREFIX, or EP_BASE is specified then the default is to set PREFIX
              to <name>-prefix.  Relative  paths  are  interpreted  with  respect  to  the  build
              directory  corresponding  to  the  source directory in which ExternalProject_Add is
              invoked.

              If SOURCE_DIR is explicitly set to an existing directory the project will be  built
              from   it.   Otherwise  a  download  step  must  be  specified  using  one  of  the
              DOWNLOAD_COMMAND, CVS_*, SVN_*, or URL options.  The URL option may  refer  locally
              to   a   directory   or  source  tarball,  or  refer  to  a  remote  tarball  (e.g.
              http://.../src.tgz).

              If UPDATE_DISCONNECTED is set, the update step is not executed  automatically  when
              building  the  main target. The update step can still be added as a step target and
              called manually. This is useful if you want to allow to build the project when  you
              are  disconnected  from  the  network  (you  might  still  need the network for the
              download  step).   This  is  disabled   by   default.    The   directory   property
              EP_UPDATE_DISCONNECTED can be used to change the default value for all the external
              projects in the current directory and its subdirectories.

       ExternalProject_Add_Step
              The ExternalProject_Add_Step function adds a custom step to an external project:

                 ExternalProject_Add_Step(<name> <step> [<option>...])

              Options are:

              COMMAND <cmd>...
                     Command line invoked by this step

              COMMENT <text>...
                     Text printed when step executes

              DEPENDEES <step>...
                     Steps on which this step depends

              DEPENDERS <step>...
                     Steps that depend on this step

              DEPENDS <file>...
                     Files on which this step depends

              BYPRODUCTS <file>...
                     Files that will be generated by this step but may  or  may  not  have  their
                     modification time updated by subsequent builds.

              ALWAYS 1
                     No stamp file, step always runs

              EXCLUDE_FROM_MAIN 1
                     Main target does not depend on this step

              WORKING_DIRECTORY <dir>
                     Working directory for command

              LOG 1  Wrap step in script to log output

              USES_TERMINAL 1
                     Give the step direct access to the terminal if possible.

              The  command line, comment, working directory, and byproducts of every standard and
              custom  step  are  processed  to   replace   tokens   <SOURCE_DIR>,   <BINARY_DIR>,
              <INSTALL_DIR>, and <TMP_DIR> with corresponding property values.

       Any  builtin  step  that specifies a <step>_COMMAND cmd... or custom step that specifies a
       COMMAND cmd... may specify additional command lines using the  form  COMMAND  cmd....   At
       build  time  the  commands  will  be  executed in order and aborted if any one fails.  For
       example:

          ... BUILD_COMMAND make COMMAND echo done ...

       specifies to run make and then echo done during  the  build  step.   Whether  the  current
       working  directory  is  preserved  between  commands  is  not  defined.  Behavior of shell
       operators like && is not defined.

       Arguments to <step>_COMMAND or COMMAND options may use generator expressions.

       ExternalProject_Get_Property
              The  ExternalProject_Get_Property  function  retrieves  external   project   target
              properties:

                 ExternalProject_Get_Property(<name> [prop1 [prop2 [...]]])

              It stores property values in variables of the same name.  Property names correspond
              to the keyword argument names of ExternalProject_Add.

       ExternalProject_Add_StepTargets
              The ExternalProject_Add_StepTargets function generates custom targets for the steps
              listed:

                 ExternalProject_Add_StepTargets(<name> [NO_DEPENDS] [step1 [step2 [...]]])

       If  NO_DEPENDS  is  set,  the  target  will not depend on the dependencies of the complete
       project. This is usually safe to use for the download, update, and patch steps that do not
       require  that  all  the dependencies are updated and built.  Using NO_DEPENDS for other of
       the default steps might break parallel builds, so you should avoid, it.  For custom steps,
       you  should consider whether or not the custom commands requires that the dependencies are
       configured, built and installed.

       If STEP_TARGETS or INDEPENDENT_STEP_TARGETS is set then ExternalProject_Add_StepTargets is
       automatically  called  at  the  end  of  matching calls to ExternalProject_Add_Step.  Pass
       STEP_TARGETS or  INDEPENDENT_STEP_TARGETS  explicitly  to  individual  ExternalProject_Add
       calls,  or implicitly to all ExternalProject_Add calls by setting the directory properties
       EP_STEP_TARGETS and EP_INDEPENDENT_STEP_TARGETS.  The INDEPENDENT version of the  argument
       and  of  the  property  will  call  ExternalProject_Add_StepTargets  with  the  NO_DEPENDS
       argument.

       If STEP_TARGETS and INDEPENDENT_STEP_TARGETS are not set, clients may still manually  call
       ExternalProject_Add_StepTargets       after       calling      ExternalProject_Add      or
       ExternalProject_Add_Step.

       This functionality is provided to make it easy to drive the steps  independently  of  each
       other by specifying targets on build command lines.  For example, you may be submitting to
       a sub-project based dashboard, where you want to drive the configure portion of the build,
       then  submit  to  the dashboard, followed by the build portion, followed by tests.  If you
       invoke a custom target that depends on a step halfway through the step  dependency  chain,
       then all the previous steps will also run to ensure everything is up to date.

       For   example,   to   drive  configure,  build  and  test  steps  independently  for  each
       ExternalProject_Add  call  in  your  project,  write  the  following  line  prior  to  any
       ExternalProject_Add calls in your CMakeLists.txt file:

          set_property(DIRECTORY PROPERTY EP_STEP_TARGETS configure build test)

       ExternalProject_Add_StepDependencies
              The  ExternalProject_Add_StepDependencies  function  add some dependencies for some
              external project step:

                 ExternalProject_Add_StepDependencies(<name> <step> [target1 [target2 [...]]])

              This function takes care to set both target and file level dependencies,  and  will
              ensure  that  parallel  builds  will  not  break.   It  should  be  used instead of
              add_dependencies() when adding a dependency for some of the step targets  generated
              by ExternalProject.

   FeatureSummary
       Macros for generating a summary of enabled/disabled features

       This   module   provides   the   macros  feature_summary(),  set_package_properties()  and
       add_feature_info().   For  compatibility  it  also  still   provides   set_package_info(),
       set_feature_info(), print_enabled_features() and print_disabled_features().

       These  macros  can  be  used to generate a summary of enabled and disabled packages and/or
       feature for a build tree:

          -- The following OPTIONAL packages have been found:
          LibXml2 (required version >= 2.4), XML processing lib, <http://xmlsoft.org>
             * Enables HTML-import in MyWordProcessor
             * Enables odt-export in MyWordProcessor
          PNG , A PNG image library. , <http://www.libpng.org/pub/png/>
             * Enables saving screenshots
          -- The following OPTIONAL packages have not been found:
          Lua51 , The Lua scripting language. , <http://www.lua.org>
             * Enables macros in MyWordProcessor
          Foo , Foo provides cool stuff.

          FEATURE_SUMMARY( [FILENAME <file>]
                           [APPEND]
                           [VAR <variable_name>]
                           [INCLUDE_QUIET_PACKAGES]
                           [FATAL_ON_MISSING_REQUIRED_PACKAGES]
                           [DESCRIPTION "Found packages:"]
                           WHAT (ALL | PACKAGES_FOUND | PACKAGES_NOT_FOUND
                                | ENABLED_FEATURES | DISABLED_FEATURES)
                         )

       The FEATURE_SUMMARY() macro can be used to print information  about  enabled  or  disabled
       packages  or  features  of a project.  By default, only the names of the features/packages
       will  be  printed  and   their   required   version   when   one   was   specified.    Use
       SET_PACKAGE_PROPERTIES() to add more useful information, like e.g.  a download URL for the
       respective package or their purpose in the project.

       The WHAT option is the only mandatory option.  Here you specify what information  will  be
       printed:

       ALL    print everything

       ENABLED_FEATURES
              the list of all features which are enabled

       DISABLED_FEATURES
              the list of all features which are disabled

       PACKAGES_FOUND
              the list of all packages which have been found

       PACKAGES_NOT_FOUND
              the list of all packages which have not been found

       OPTIONAL_PACKAGES_FOUND
              only those packages which have been found which have the type OPTIONAL

       OPTIONAL_PACKAGES_NOT_FOUND
              only those packages which have not been found which have the type OPTIONAL

       RECOMMENDED_PACKAGES_FOUND
              only those packages which have been found which have the type RECOMMENDED

       RECOMMENDED_PACKAGES_NOT_FOUND
              only those packages which have not been found which have the type RECOMMENDED

       REQUIRED_PACKAGES_FOUND
              only those packages which have been found which have the type REQUIRED

       REQUIRED_PACKAGES_NOT_FOUND
              only those packages which have not been found which have the type REQUIRED

       RUNTIME_PACKAGES_FOUND
              only those packages which have been found which have the type RUNTIME

       RUNTIME_PACKAGES_NOT_FOUND
              only those packages which have not been found which have the type RUNTIME

       With  the  exception  of the ALL value, these values can be combined in order to customize
       the output. For example:

          feature_summary(WHAT ENABLED_FEATURES DISABLED_FEATURES)

       If a FILENAME is given, the information is printed into this file.  If APPEND is used,  it
       is appended to this file, otherwise the file is overwritten if it already existed.  If the
       VAR option is used, the information is "printed" into the specified variable.  If FILENAME
       is  not  used, the information is printed to the terminal.  Using the DESCRIPTION option a
       description or headline can be set which will be printed above  the  actual  content.   If
       INCLUDE_QUIET_PACKAGES  is  given, packages which have been searched with find_package(...
       QUIET)   will    also    be    listed.     By    default    they    are    skipped.     If
       FATAL_ON_MISSING_REQUIRED_PACKAGES is given, CMake will abort if a package which is marked
       as REQUIRED has not been found.

       Example 1, append everything to a file:

          feature_summary(WHAT ALL
                          FILENAME ${CMAKE_BINARY_DIR}/all.log APPEND)

       Example 2, print the enabled features into  the  variable  enabledFeaturesText,  including
       QUIET packages:

          feature_summary(WHAT ENABLED_FEATURES
                          INCLUDE_QUIET_PACKAGES
                          DESCRIPTION "Enabled Features:"
                          VAR enabledFeaturesText)
          message(STATUS "${enabledFeaturesText}")

          SET_PACKAGE_PROPERTIES(<name> PROPERTIES
                                 [ URL <url> ]
                                 [ DESCRIPTION <description> ]
                                 [ TYPE (RUNTIME|OPTIONAL|RECOMMENDED|REQUIRED) ]
                                 [ PURPOSE <purpose> ]
                                )

       Use  this macro to set up information about the named package, which can then be displayed
       via FEATURE_SUMMARY().  This can be done either directly in  the  Find-module  or  in  the
       project  which  uses  the  module  after  the find_package() call.  The features for which
       information can be set are added automatically by the find_package() command.

       URL: this should be the homepage of the package, or something similar.   Ideally  this  is
       set already directly in the Find-module.

       DESCRIPTION: A short description what that package is, at most one sentence.  Ideally this
       is set already directly in the Find-module.

       TYPE: What type of dependency has the using project on that package.  Default is OPTIONAL.
       In this case it is a package which can be used by the project when available at buildtime,
       but it also work without.  RECOMMENDED is similar to  OPTIONAL,  i.e.   the  project  will
       build  if the package is not present, but the functionality of the resulting binaries will
       be severly limited.  If a REQUIRED package is not available at buildtime, the project  may
       not even build.  This can be combined with the FATAL_ON_MISSING_REQUIRED_PACKAGES argument
       for feature_summary().  Last, a RUNTIME package is a package which is actually not used at
       all  during  the build, but which is required for actually running the resulting binaries.
       So if such a package is missing, the project can still be built, but it may not work later
       on.   If  set_package_properties()  is  called  multiple  times  for the same package with
       different TYPEs, the TYPE is  only  changed  to  higher  TYPEs  (  RUNTIME  <  OPTIONAL  <
       RECOMMENDED < REQUIRED ), lower TYPEs are ignored.  The TYPE property is project-specific,
       so it cannot be set by the Find-module, but must be set in the project.

       PURPOSE: This describes which features this package enables in the project, i.e.  it tells
       the    user    what    functionality    he   gets   in   the   resulting   binaries.    If
       set_package_properties() is called multiple times for a package,  all  PURPOSE  properties
       are  appended  to a list of purposes of the package in the project.  As the TYPE property,
       also the PURPOSE property is project-specific, so it cannot be set by the Find-module, but
       must be set in the project.

       Example for setting the info for a package:

          find_package(LibXml2)
          set_package_properties(LibXml2 PROPERTIES
                                 DESCRIPTION "A XML processing library."
                                 URL "http://xmlsoft.org/")

          set_package_properties(LibXml2 PROPERTIES
                                 TYPE RECOMMENDED
                                 PURPOSE "Enables HTML-import in MyWordProcessor")
          ...
          set_package_properties(LibXml2 PROPERTIES
                                 TYPE OPTIONAL
                                 PURPOSE "Enables odt-export in MyWordProcessor")

          find_package(DBUS)
          set_package_properties(DBUS PROPERTIES
            TYPE RUNTIME
            PURPOSE "Necessary to disable the screensaver during a presentation" )

          ADD_FEATURE_INFO(<name> <enabled> <description>)

       Use  this  macro  to  add  information  about  a feature with the given <name>.  <enabled>
       contains whether this feature is enabled or not, <description> is a  text  describing  the
       feature.   The  information  can be displayed using feature_summary() for ENABLED_FEATURES
       and DISABLED_FEATURES respectively.

       Example for setting the info for a feature:

          option(WITH_FOO "Help for foo" ON)
          add_feature_info(Foo WITH_FOO "The Foo feature provides very cool stuff.")

       The following macros are provided for compatibility with previous CMake versions:

          SET_PACKAGE_INFO(<name> <description> [<url> [<purpose>] ] )

       Use this macro to set up information about the named package, which can then be  displayed
       via  FEATURE_SUMMARY().   This  can  be  done either directly in the Find-module or in the
       project which uses the module after the  find_package()  call.   The  features  for  which
       information can be set are added automatically by the find_package() command.

          PRINT_ENABLED_FEATURES()

       Does the same as FEATURE_SUMMARY(WHAT ENABLED_FEATURES DESCRIPTION "Enabled features:")

          PRINT_DISABLED_FEATURES()

       Does the same as FEATURE_SUMMARY(WHAT DISABLED_FEATURES DESCRIPTION "Disabled features:")

          SET_FEATURE_INFO(<name> <description> [<url>] )

       Does the same as SET_PACKAGE_INFO(<name> <description> <url> )

   FindALSA
       Find alsa

       Find the alsa libraries (asound)

          This module defines the following variables:
             ALSA_FOUND       - True if ALSA_INCLUDE_DIR & ALSA_LIBRARY are found
             ALSA_LIBRARIES   - Set when ALSA_LIBRARY is found
             ALSA_INCLUDE_DIRS - Set when ALSA_INCLUDE_DIR is found

          ALSA_INCLUDE_DIR - where to find asoundlib.h, etc.
          ALSA_LIBRARY     - the asound library
          ALSA_VERSION_STRING - the version of alsa found (since CMake 2.8.8)

   FindArmadillo
       Find Armadillo

       Find the Armadillo C++ library

       Using Armadillo:

          find_package(Armadillo REQUIRED)
          include_directories(${ARMADILLO_INCLUDE_DIRS})
          add_executable(foo foo.cc)
          target_link_libraries(foo ${ARMADILLO_LIBRARIES})

       This module sets the following variables:

          ARMADILLO_FOUND - set to true if the library is found
          ARMADILLO_INCLUDE_DIRS - list of required include directories
          ARMADILLO_LIBRARIES - list of libraries to be linked
          ARMADILLO_VERSION_MAJOR - major version number
          ARMADILLO_VERSION_MINOR - minor version number
          ARMADILLO_VERSION_PATCH - patch version number
          ARMADILLO_VERSION_STRING - version number as a string (ex: "1.0.4")
          ARMADILLO_VERSION_NAME - name of the version (ex: "Antipodean Antileech")

   FindASPELL
       Try to find ASPELL

       Once done this will define

          ASPELL_FOUND - system has ASPELL
          ASPELL_EXECUTABLE - the ASPELL executable
          ASPELL_INCLUDE_DIR - the ASPELL include directory
          ASPELL_LIBRARIES - The libraries needed to use ASPELL
          ASPELL_DEFINITIONS - Compiler switches required for using ASPELL

   FindAVIFile
       Locate AVIFILE library and include paths

       AVIFILE  (http://avifile.sourceforge.net/)is  a  set of libraries for i386 machines to use
       various AVI codecs.  Support  is  limited  beyond  Linux.   Windows  provides  native  AVI
       support, and so doesn't need this library.  This module defines

          AVIFILE_INCLUDE_DIR, where to find avifile.h , etc.
          AVIFILE_LIBRARIES, the libraries to link against
          AVIFILE_DEFINITIONS, definitions to use when compiling
          AVIFILE_FOUND, If false, don't try to use AVIFILE

   FindBISON
       Find bison executable and provide a macro to generate custom build rules.

       The module defines the following variables:

       BISON_EXECUTABLE
              path to the bison program

       BISON_VERSION
              version of bison

       BISON_FOUND
              true if the program was found

       The  minimum  required  version of bison can be specified using the standard CMake syntax,
       e.g.  find_package(BISON 2.1.3).

       If bison is found, the module defines the macro:

          BISON_TARGET(<Name> <YaccInput> <CodeOutput>
                       [COMPILE_FLAGS <flags>]
                       [DEFINES_FILE <file>]
                       [VERBOSE <file>]
                       )

       which will create a custom rule to generate a parser.  <YaccInput> is the path to  a  yacc
       file.   <CodeOutput>  is the name of the source file generated by bison.  A header file is
       also be generated, and contains the token list.

       The options are:

       COMPILE_FLAGS <flags>
              Specify flags to be added to the bison command line.

       DEFINES_FILE <file>
              Specify a non-default header <file> to be generated by bison.

       VERBOSE <file>
              Tell bison to write verbose descriptions of the grammar and  parser  to  the  given
              <file>.

       The macro defines the following variables:

       BISON_<Name>_DEFINED
              true is the macro ran successfully

       BISON_<Name>_INPUT
              The input source file, an alias for <YaccInput>

       BISON_<Name>_OUTPUT_SOURCE
              The source file generated by bison

       BISON_<Name>_OUTPUT_HEADER
              The header file generated by bison

       BISON_<Name>_OUTPUTS
              The sources files generated by bison

       BISON_<Name>_COMPILE_FLAGS
              Options used in the bison command line

       Example usage:

          find_package(BISON)
          BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp
                       DEFINES_FILE ${CMAKE_CURRENT_BINARY_DIR}/parser.h)
          add_executable(Foo main.cpp ${BISON_MyParser_OUTPUTS})

   FindBLAS
       Find BLAS library

       This  module  finds  an  installed fortran library that implements the BLAS linear-algebra
       interface (see http://www.netlib.org/blas/).  The list of libraries searched for is  taken
       from      the      autoconf      macro      file,      acx_blas.m4     (distributed     at
       http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).

       This module sets the following variables:

          BLAS_FOUND - set to true if a library implementing the BLAS interface
            is found
          BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
            and -L).
          BLAS_LIBRARIES - uncached list of libraries (using full path name) to
            link against to use BLAS
          BLAS95_LIBRARIES - uncached list of libraries (using full path name)
            to link against to use BLAS95 interface
          BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
            is found
          BLA_STATIC  if set on this determines what kind of linkage we do (static)
          BLA_VENDOR  if set checks only the specified vendor, if not set checks
             all the possibilities
          BLA_F95     if set on tries to find the f95 interfaces for BLAS/LAPACK

       #########  ##  List  of  vendors  (BLA_VENDOR)  valid  in   this   module   #   Goto,ATLAS
       PhiPACK,CXML,DXML,SunPerf,SCSL,SGIMATH,IBMESSL,Intel10_32     (intel     mkl     v10    32

       mkl

   FindBacktrace
       Find provider for backtrace(3).

       Checks if OS supports backtrace(3) via either libc or custom library.  This module defines
       the following variables:

       Backtrace_HEADER
              The header file needed for backtrace(3). Cached.  Could be forcibly set by user.

       Backtrace_INCLUDE_DIRS
              The include directories needed to use backtrace(3) header.

       Backtrace_LIBRARIES
              The libraries (linker flags) needed to use backtrace(3), if any.

       Backtrace_FOUND
              Is set if and only if backtrace(3) support detected.

       The following cache variables are also available to set or use:

       Backtrace_LIBRARY
              The external library providing backtrace, if any.

       Backtrace_INCLUDE_DIR
              The directory holding the backtrace(3) header.

       Typical usage is to generate of header file using configure_file() with the contents  like
       the following:

          #cmakedefine01 Backtrace_FOUND
          #if Backtrace_FOUND
          # include <${Backtrace_HEADER}>
          #endif

       And then reference that generated header file in actual source.

   FindBoost
       Find Boost include dirs and libraries

       Use this module by invoking find_package with the form:

          find_package(Boost
            [version] [EXACT]      # Minimum or EXACT version e.g. 1.36.0
            [REQUIRED]             # Fail with error if Boost is not found
            [COMPONENTS <libs>...] # Boost libraries by their canonical name
            )                      # e.g. "date_time" for "libboost_date_time"

       This   module  finds  headers  and  requested  component  libraries  OR  a  CMake  package
       configuration file provided by a "Boost CMake" build.  For the latter  case  skip  to  the
       "Boost CMake" section below.  For the former case results are reported in variables:

          Boost_FOUND            - True if headers and requested libraries were found
          Boost_INCLUDE_DIRS     - Boost include directories
          Boost_LIBRARY_DIRS     - Link directories for Boost libraries
          Boost_LIBRARIES        - Boost component libraries to be linked
          Boost_<C>_FOUND        - True if component <C> was found (<C> is upper-case)
          Boost_<C>_LIBRARY      - Libraries to link for component <C> (may include
                                   target_link_libraries debug/optimized keywords)
          Boost_VERSION          - BOOST_VERSION value from boost/version.hpp
          Boost_LIB_VERSION      - Version string appended to library filenames
          Boost_MAJOR_VERSION    - Boost major version number (X in X.y.z)
          Boost_MINOR_VERSION    - Boost minor version number (Y in x.Y.z)
          Boost_SUBMINOR_VERSION - Boost subminor version number (Z in x.y.Z)
          Boost_LIB_DIAGNOSTIC_DEFINITIONS (Windows)
                                 - Pass to add_definitions() to have diagnostic
                                   information about Boost's automatic linking
                                   displayed during compilation

       This module reads hints about search locations from variables:

          BOOST_ROOT             - Preferred installation prefix
           (or BOOSTROOT)
          BOOST_INCLUDEDIR       - Preferred include directory e.g. <prefix>/include
          BOOST_LIBRARYDIR       - Preferred library directory e.g. <prefix>/lib
          Boost_NO_SYSTEM_PATHS  - Set to ON to disable searching in locations not
                                   specified by these hint variables. Default is OFF.
          Boost_ADDITIONAL_VERSIONS
                                 - List of Boost versions not known to this module
                                   (Boost install locations may contain the version)

       and saves search results persistently in CMake cache entries:

          Boost_INCLUDE_DIR         - Directory containing Boost headers
          Boost_LIBRARY_DIR_RELEASE - Directory containing release Boost libraries
          Boost_LIBRARY_DIR_DEBUG   - Directory containing debug Boost libraries
          Boost_<C>_LIBRARY_DEBUG   - Component <C> library debug variant
          Boost_<C>_LIBRARY_RELEASE - Component <C> library release variant

       The following IMPORTED targets are also defined:

          Boost::boost                  - Target for header-only dependencies
                                          (Boost include directory)
          Boost::<C>                    - Target for specific component dependency
                                          (shared or static library); <C> is lower-
                                          case
          Boost::diagnostic_definitions - interface target to enable diagnostic
                                          information about Boost's automatic linking
                                          during compilation (adds BOOST_LIB_DIAGNOSTIC)
          Boost::disable_autolinking    - interface target to disable automatic
                                          linking with MSVC (adds BOOST_ALL_NO_LIB)
          Boost::dynamic_linking        - interface target to enable dynamic linking
                                          linking with MSVC (adds BOOST_ALL_DYN_LINK)

       Implicit   dependencies   such   as  Boost::filesystem  requiring  Boost::system  will  be
       automatically detected  and  satisfied,  even  if  system  is  not  specified  when  using
       find_package  and  if  Boost::system  is  not  added  to  target_link_libraries.  If using
       Boost::thread, then Thread::Thread will also be added automatically.

       It is important to note that  the  imported  targets  behave  differently  than  variables
       created  by  this  module:  multiple calls to find_package(Boost) in the same directory or
       sub-directories with different options (e.g. static  or  shared)  will  not  override  the
       values of the targets created by the first call.

       Users  may  set  these  hints or results as cache entries.  Projects should not read these
       entries directly but instead use the above result variables.  Note that  some  hint  names
       start  in  upper-case "BOOST".  One may specify these as environment variables if they are
       not specified as CMake variables or cache entries.

       This module first searches for the Boost header  files  using  the  above  hint  variables
       (excluding  BOOST_LIBRARYDIR) and saves the result in Boost_INCLUDE_DIR.  Then it searches
       for requested component libraries using the above hints  (excluding  BOOST_INCLUDEDIR  and
       Boost_ADDITIONAL_VERSIONS), "lib" directories near Boost_INCLUDE_DIR, and the library name
       configuration settings below.  It saves the library directories in Boost_LIBRARY_DIR_DEBUG
       and  Boost_LIBRARY_DIR_RELEASE and individual library locations in Boost_<C>_LIBRARY_DEBUG
       and Boost_<C>_LIBRARY_RELEASE.  When one changes settings used by previous searches in the
       same  build  tree  (excluding  environment variables) this module discards previous search
       results affected by the changes and searches again.

       Boost libraries come in many variants encoded in their file name.  Users or  projects  may
       tell this module which variant to find by setting variables:

          Boost_USE_MULTITHREADED  - Set to OFF to use the non-multithreaded
                                     libraries ('mt' tag).  Default is ON.
          Boost_USE_STATIC_LIBS    - Set to ON to force the use of the static
                                     libraries.  Default is OFF.
          Boost_USE_STATIC_RUNTIME - Set to ON or OFF to specify whether to use
                                     libraries linked statically to the C++ runtime
                                     ('s' tag).  Default is platform dependent.
          Boost_USE_DEBUG_RUNTIME  - Set to ON or OFF to specify whether to use
                                     libraries linked to the MS debug C++ runtime
                                     ('g' tag).  Default is ON.
          Boost_USE_DEBUG_PYTHON   - Set to ON to use libraries compiled with a
                                     debug Python build ('y' tag). Default is OFF.
          Boost_USE_STLPORT        - Set to ON to use libraries compiled with
                                     STLPort ('p' tag).  Default is OFF.
          Boost_USE_STLPORT_DEPRECATED_NATIVE_IOSTREAMS
                                   - Set to ON to use libraries compiled with
                                     STLPort deprecated "native iostreams"
                                     ('n' tag).  Default is OFF.
          Boost_COMPILER           - Set to the compiler-specific library suffix
                                     (e.g. "-gcc43").  Default is auto-computed
                                     for the C++ compiler in use.
          Boost_THREADAPI          - Suffix for "thread" component library name,
                                     such as "pthread" or "win32".  Names with
                                     and without this suffix will both be tried.
          Boost_NAMESPACE          - Alternate namespace used to build boost with
                                     e.g. if set to "myboost", will search for
                                     myboost_thread instead of boost_thread.

       Other variables one may set to control this module are:

          Boost_DEBUG              - Set to ON to enable debug output from FindBoost.
                                     Please enable this before filing any bug report.
          Boost_DETAILED_FAILURE_MSG
                                   - Set to ON to add detailed information to the
                                     failure message even when the REQUIRED option
                                     is not given to the find_package call.
          Boost_REALPATH           - Set to ON to resolve symlinks for discovered
                                     libraries to assist with packaging.  For example,
                                     the "system" component library may be resolved to
                                     "/usr/lib/libboost_system.so.1.42.0" instead of
                                     "/usr/lib/libboost_system.so".  This does not
                                     affect linking and should not be enabled unless
                                     the user needs this information.
          Boost_LIBRARY_DIR        - Default value for Boost_LIBRARY_DIR_RELEASE and
                                     Boost_LIBRARY_DIR_DEBUG.

       On  Visual  Studio  and  Borland  compilers  Boost  headers  request  automatic linking to
       corresponding libraries.  This requires matching libraries  to  be  linked  explicitly  or
       available  in the link library search path.  In this case setting Boost_USE_STATIC_LIBS to
       OFF may not achieve dynamic linking.  Boost automatic linking  typically  requests  static
       libraries with a few exceptions (such as Boost.Python).  Use:

          add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS})

       to ask Boost to report information about automatic linking requests.

       Example to find Boost headers only:

          find_package(Boost 1.36.0)
          if(Boost_FOUND)
            include_directories(${Boost_INCLUDE_DIRS})
            add_executable(foo foo.cc)
          endif()

       Example to find Boost libraries and use imported targets:

          find_package(Boost 1.56 REQUIRED COMPONENTS
                       date_time filesystem iostreams)
          add_executable(foo foo.cc)
          target_link_libraries(foo Boost::date_time Boost::filesystem
                                    Boost::iostreams)

       Example to find Boost headers and some static libraries:

          set(Boost_USE_STATIC_LIBS        ON) # only find static libs
          set(Boost_USE_MULTITHREADED      ON)
          set(Boost_USE_STATIC_RUNTIME    OFF)
          find_package(Boost 1.36.0 COMPONENTS date_time filesystem system ...)
          if(Boost_FOUND)
            include_directories(${Boost_INCLUDE_DIRS})
            add_executable(foo foo.cc)
            target_link_libraries(foo ${Boost_LIBRARIES})
          endif()

   Boost CMake
       If  Boost was built using the boost-cmake project it provides a package configuration file
       for use with find_package's Config mode.  This module looks for the package  configuration
       file  called  BoostConfig.cmake or boost-config.cmake and stores the result in cache entry
       "Boost_DIR".  If found, the package configuration file is loaded and this  module  returns
       with  no  further  action.  See documentation of the Boost CMake package configuration for
       details on what it provides.

       Set Boost_NO_BOOST_CMAKE to ON to disable the search for boost-cmake.

   FindBullet
       Try to find the Bullet physics engine

          This module defines the following variables

          BULLET_FOUND - Was bullet found
          BULLET_INCLUDE_DIRS - the Bullet include directories
          BULLET_LIBRARIES - Link to this, by default it includes
                             all bullet components (Dynamics,
                             Collision, LinearMath, & SoftBody)

          This module accepts the following variables

          BULLET_ROOT - Can be set to bullet install path or Windows build path

   FindBZip2
       Try to find BZip2

       Once done this will define

          BZIP2_FOUND - system has BZip2
          BZIP2_INCLUDE_DIR - the BZip2 include directory
          BZIP2_LIBRARIES - Link these to use BZip2
          BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_
          BZIP2_VERSION_STRING - the version of BZip2 found (since CMake 2.8.8)

   FindCABLE
       Find CABLE

       This module finds if CABLE is  installed  and  determines  where  the  include  files  and
       libraries are.  This code sets the following variables:

          CABLE             the path to the cable executable
          CABLE_TCL_LIBRARY the path to the Tcl wrapper library
          CABLE_INCLUDE_DIR the path to the include directory

       To  build Tcl wrappers, you should add shared library and link it to ${CABLE_TCL_LIBRARY}.
       You should also add ${CABLE_INCLUDE_DIR} as an include directory.

   FindCoin3D
       Find Coin3D (Open Inventor)

       Coin3D is an implementation of the Open Inventor API.  It  provides  data  structures  and
       algorithms for 3D visualization.

       This module defines the following variables

          COIN3D_FOUND         - system has Coin3D - Open Inventor
          COIN3D_INCLUDE_DIRS  - where the Inventor include directory can be found
          COIN3D_LIBRARIES     - Link to this to use Coin3D

   FindCUDA
       Tools for building CUDA C files: libraries and build dependencies.

       This  script  locates  the NVIDIA CUDA C tools.  It should work on linux, windows, and mac
       and should be reasonably up to date with CUDA C releases.

       This script makes use of the standard find_package arguments of  <VERSION>,  REQUIRED  and
       QUIET.  CUDA_FOUND will report if an acceptable version of CUDA was found.

       The  script  will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR if the prefix cannot be
       determined by the location of nvcc in  the  system  path  and  REQUIRED  is  specified  to
       find_package().   To  use a different installed version of the toolkit set the environment
       variable  CUDA_BIN_PATH  before  running  cmake  (e.g.    CUDA_BIN_PATH=/usr/local/cuda1.0
       instead  of  the  default /usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring.
       If you change the value of CUDA_TOOLKIT_ROOT_DIR, various components that  depend  on  the
       path will be relocated.

       It  might  be  necessary to set CUDA_TOOLKIT_ROOT_DIR manually on certain platforms, or to
       use a cuda runtime not installed in the  default  location.   In  newer  versions  of  the
       toolkit  the  cuda  library  is included with the graphics driver- be sure that the driver
       version matches what is needed by the cuda runtime version.

       The following variables affect the behavior of the macros in the script  (in  alphebetical
       order).   Note that any of these flags can be changed multiple times in the same directory
       before  calling  CUDA_ADD_EXECUTABLE,  CUDA_ADD_LIBRARY,  CUDA_COMPILE,  CUDA_COMPILE_PTX,
       CUDA_COMPILE_FATBIN, CUDA_COMPILE_CUBIN or CUDA_WRAP_SRCS:

          CUDA_64_BIT_DEVICE_CODE (Default matches host bit size)
          -- Set to ON to compile for 64 bit device code, OFF for 32 bit device code.
             Note that making this different from the host code when generating object
             or C files from CUDA code just won't work, because size_t gets defined by
             nvcc in the generated source.  If you compile to PTX and then load the
             file yourself, you can mix bit sizes between device and host.

          CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON)
          -- Set to ON if you want the custom build rule to be attached to the source
             file in Visual Studio.  Turn OFF if you add the same cuda file to multiple
             targets.

             This allows the user to build the target from the CUDA file; however, bad
             things can happen if the CUDA source file is added to multiple targets.
             When performing parallel builds it is possible for the custom build
             command to be run more than once and in parallel causing cryptic build
             errors.  VS runs the rules for every source file in the target, and a
             source can have only one rule no matter how many projects it is added to.
             When the rule is run from multiple targets race conditions can occur on
             the generated file.  Eventually everything will get built, but if the user
             is unaware of this behavior, there may be confusion.  It would be nice if
             this script could detect the reuse of source files across multiple targets
             and turn the option off for the user, but no good solution could be found.

          CUDA_BUILD_CUBIN (Default OFF)
          -- Set to ON to enable and extra compilation pass with the -cubin option in
             Device mode. The output is parsed and register, shared memory usage is
             printed during build.

          CUDA_BUILD_EMULATION (Default OFF for device mode)
          -- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files
             when CUDA_BUILD_EMULATION is TRUE.

          CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR)
          -- Set to the path you wish to have the generated files placed.  If it is
             blank output files will be placed in CMAKE_CURRENT_BINARY_DIR.
             Intermediate files will always be placed in
             CMAKE_CURRENT_BINARY_DIR/CMakeFiles.

          CUDA_HOST_COMPILATION_CPP (Default ON)
          -- Set to OFF for C compilation of host code.

          CUDA_HOST_COMPILER (Default CMAKE_C_COMPILER, $(VCInstallDir)/bin for VS)
          -- Set the host compiler to be used by nvcc.  Ignored if -ccbin or
             --compiler-bindir is already present in the CUDA_NVCC_FLAGS or
             CUDA_NVCC_FLAGS_<CONFIG> variables.  For Visual Studio targets
             $(VCInstallDir)/bin is a special value that expands out to the path when
             the command is run from withing VS.

          CUDA_NVCC_FLAGS
          CUDA_NVCC_FLAGS_<CONFIG>
          -- Additional NVCC command line arguments.  NOTE: multiple arguments must be
             semi-colon delimited (e.g. --compiler-options;-Wall)

          CUDA_PROPAGATE_HOST_FLAGS (Default ON)
          -- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration
             dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the
             host compiler through nvcc's -Xcompiler flag.  This helps make the
             generated host code match the rest of the system better.  Sometimes
             certain flags give nvcc problems, and this will help you turn the flag
             propagation off.  This does not affect the flags supplied directly to nvcc
             via CUDA_NVCC_FLAGS or through the OPTION flags specified through
             CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS.  Flags used for
             shared library compilation are not affected by this flag.

          CUDA_SEPARABLE_COMPILATION (Default OFF)
          -- If set this will enable separable compilation for all CUDA runtime object
             files.  If used outside of CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY
             (e.g. calling CUDA_WRAP_SRCS directly),
             CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME and
             CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS should be called.

          CUDA_SOURCE_PROPERTY_FORMAT
          -- If this source file property is set, it can override the format specified
             to CUDA_WRAP_SRCS (OBJ, PTX, CUBIN, or FATBIN).  If an input source file
             is not a .cu file, setting this file will cause it to be treated as a .cu
             file. See documentation for set_source_files_properties on how to set
             this property.

          CUDA_USE_STATIC_CUDA_RUNTIME (Default ON)
          -- When enabled the static version of the CUDA runtime library will be used
             in CUDA_LIBRARIES.  If the version of CUDA configured doesn't support
             this option, then it will be silently disabled.

          CUDA_VERBOSE_BUILD (Default OFF)
          -- Set to ON to see all the commands used when building the CUDA file.  When
             using a Makefile generator the value defaults to VERBOSE (run make
             VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will
             always print the output.

       The script creates the following macros (in alphebetical order):

          CUDA_ADD_CUFFT_TO_TARGET( cuda_target )
          -- Adds the cufft library to the target (can be any target).  Handles whether
             you are in emulation mode or not.

          CUDA_ADD_CUBLAS_TO_TARGET( cuda_target )
          -- Adds the cublas library to the target (can be any target).  Handles
             whether you are in emulation mode or not.

          CUDA_ADD_EXECUTABLE( cuda_target file0 file1 ...
                               [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
          -- Creates an executable "cuda_target" which is made up of the files
             specified.  All of the non CUDA C files are compiled using the standard
             build rules specified by CMAKE and the cuda files are compiled to object
             files using nvcc and the host compiler.  In addition CUDA_INCLUDE_DIRS is
             added automatically to include_directories().  Some standard CMake target
             calls can be used on the target after calling this macro
             (e.g. set_target_properties and target_link_libraries), but setting
             properties that adjust compilation flags will not affect code compiled by
             nvcc.  Such flags should be modified before calling CUDA_ADD_EXECUTABLE,
             CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS.

          CUDA_ADD_LIBRARY( cuda_target file0 file1 ...
                            [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
          -- Same as CUDA_ADD_EXECUTABLE except that a library is created.

          CUDA_BUILD_CLEAN_TARGET()
          -- Creates a convience target that deletes all the dependency files
             generated.  You should make clean after running this target to ensure the
             dependency files get regenerated.

          CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE]
                        [OPTIONS ...] )
          -- Returns a list of generated files from the input source files to be used
             with ADD_LIBRARY or ADD_EXECUTABLE.

          CUDA_COMPILE_PTX( generated_files file0 file1 ... [OPTIONS ...] )
          -- Returns a list of PTX files generated from the input source files.

          CUDA_COMPILE_FATBIN( generated_files file0 file1 ... [OPTIONS ...] )
          -- Returns a list of FATBIN files generated from the input source files.

          CUDA_COMPILE_CUBIN( generated_files file0 file1 ... [OPTIONS ...] )
          -- Returns a list of CUBIN files generated from the input source files.

          CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME( output_file_var
                                                               cuda_target
                                                               object_files )
          -- Compute the name of the intermediate link file used for separable
             compilation.  This file name is typically passed into
             CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS.  output_file_var is produced
             based on cuda_target the list of objects files that need separable
             compilation as specified by object_files.  If the object_files list is
             empty, then output_file_var will be empty.  This function is called
             automatically for CUDA_ADD_LIBRARY and CUDA_ADD_EXECUTABLE.  Note that
             this is a function and not a macro.

          CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )
          -- Sets the directories that should be passed to nvcc
             (e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu
             files.

          CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS( output_file_var cuda_target
                                                   nvcc_flags object_files)

          -- Generates the link object required by separable compilation from the given
             object files.  This is called automatically for CUDA_ADD_EXECUTABLE and
             CUDA_ADD_LIBRARY, but can be called manually when using CUDA_WRAP_SRCS
             directly.  When called from CUDA_ADD_LIBRARY or CUDA_ADD_EXECUTABLE the
             nvcc_flags passed in are the same as the flags passed in via the OPTIONS
             argument.  The only nvcc flag added automatically is the bitness flag as
             specified by CUDA_64_BIT_DEVICE_CODE.  Note that this is a function
             instead of a macro.

          CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...
                           [STATIC | SHARED | MODULE] [OPTIONS ...] )
          -- This is where all the magic happens.  CUDA_ADD_EXECUTABLE,
             CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this
             function under the hood.

             Given the list of files (file0 file1 ... fileN) this macro generates
             custom commands that generate either PTX or linkable objects (use "PTX" or
             "OBJ" for the format argument to switch).  Files that don't end with .cu
             or have the HEADER_FILE_ONLY property are ignored.

             The arguments passed in after OPTIONS are extra command line options to
             give to nvcc.  You can also specify per configuration options by
             specifying the name of the configuration followed by the options.  General
             options must preceed configuration specific options.  Not all
             configurations need to be specified, only the ones provided will be used.

                OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag"
                DEBUG -g
                RELEASE --use_fast_math
                RELWITHDEBINFO --use_fast_math;-g
                MINSIZEREL --use_fast_math

             For certain configurations (namely VS generating object files with
             CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will
             be produced for the given cuda file.  This is because when you add the
             cuda file to Visual Studio it knows that this file produces an object file
             and will link in the resulting object file automatically.

             This script will also generate a separate cmake script that is used at
             build time to invoke nvcc.  This is for several reasons.

               1. nvcc can return negative numbers as return values which confuses
               Visual Studio into thinking that the command succeeded.  The script now
               checks the error codes and produces errors when there was a problem.

               2. nvcc has been known to not delete incomplete results when it
               encounters problems.  This confuses build systems into thinking the
               target was generated when in fact an unusable file exists.  The script
               now deletes the output files if there was an error.

               3. By putting all the options that affect the build into a file and then
               make the build rule dependent on the file, the output files will be
               regenerated when the options change.

             This script also looks at optional arguments STATIC, SHARED, or MODULE to
             determine when to target the object compilation for a shared library.
             BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in
             CUDA_ADD_LIBRARY.  On some systems special flags are added for building
             objects intended for shared libraries.  A preprocessor macro,
             <target_name>_EXPORTS is defined when a shared library compilation is
             detected.

             Flags passed into add_definitions with -D or /D are passed along to nvcc.

       The script defines the following variables:

          CUDA_VERSION_MAJOR    -- The major version of cuda as reported by nvcc.
          CUDA_VERSION_MINOR    -- The minor version.
          CUDA_VERSION
          CUDA_VERSION_STRING   -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR

          CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set).
          CUDA_SDK_ROOT_DIR     -- Path to the CUDA SDK.  Use this to find files in the
                                   SDK.  This script will not directly support finding
                                   specific libraries or headers, as that isn't
                                   supported by NVIDIA.  If you want to change
                                   libraries when the path changes see the
                                   FindCUDA.cmake script for an example of how to clear
                                   these variables.  There are also examples of how to
                                   use the CUDA_SDK_ROOT_DIR to locate headers or
                                   libraries, if you so choose (at your own risk).
          CUDA_INCLUDE_DIRS     -- Include directory for cuda headers.  Added automatically
                                   for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY.

          generator was used instead of the Perl one,
          regardless of which scripting language the
          user had installed.

          CXXTEST_TESTGEN_ARGS (since CMake 2.8.3)
              Specify a list of options to pass to the CxxTest code
              generator.  If not defined, --error-printer is
              passed.

              The full path to the Perl or Python executable on the system

       MACROS for optional use by CMake users:

          CXXTEST_ADD_TEST(<test_name> <gen_source_file> <input_files_to_testgen...>)
             Creates a CxxTest runner and adds it to the CTest testing suite
             Parameters:
                 test_name               The name of the test
                 gen_source_file         The generated source filename to be
                                         generated by CxxTest

                                         CxxTest::TestSuite's to be included in
                                         this runner

          #==============
          Example Usage:

          find_package(CxxTest)
          if(CXXTEST_FOUND)
              include_directories(${CXXTEST_INCLUDE_DIR})
              enable_testing()

              CXXTEST_ADD_TEST(unittest_foo foo_test.cc
                                ${CMAKE_CURRENT_SOURCE_DIR}/foo_test.h)
              target_link_libraries(unittest_foo foo) # as needed
          endif()

          This will (if CxxTest is found):
          1. Invoke the testgen executable to autogenerate foo_test.cc in the
             binary tree from "foo_test.h" in the current source directory.
          2. Create an executable and test called unittest_foo.

          #=============
          Example foo_test.h:

          #include <cxxtest/TestSuite.h>

          class MyTestSuite : public CxxTest::TestSuite
          {
          public:
             void testAddition( void )
             {
                TS_ASSERT( 1 + 1 > 1 );
                TS_ASSERT_EQUALS( 1 + 1, 2 );
             }
          };

   FindDCMTK
       Find DCMTK libraries and applications

       The module defines the following variables:

          DCMTK_INCLUDE_DIRS  - Directories to include to use DCMTK
          DCMTK_LIBRARIES     - Files to link against to use DCMTK
          DCMTK_FOUND         - If false, don't try to use DCMTK
          DCMTK_DIR           - (optional) Source directory for DCMTK

   Compatibility
       This module is able  to  find  a  version  of  DCMTK  that  does  or  does  not  export  a
       DCMTKConfig.cmake file. It applies a two step process:

       • Step 1:  Attempt to find DCMTK version providing a DCMTKConfig.cmake file.

       • Step  2:   If  step  1  failed, rely on FindDCMTK.cmake to set DCMTK_* variables details
         below.

       Recent DCMTK provides a DCMTKConfig.cmake package configuration file. To  exclusively  use
       the  package  configuration file (recommended when possible), pass the NO_MODULE option to
       find_package(). For example, find_package(DCMTK NO_MODULE).  This requires official  DCMTK
       snapshot 3.6.1_20140617 or newer.

       Until  all  clients  update  to  the more recent DCMTK, build systems will need to support
       different versions of DCMTK.

       On any given system, the following combinations of DCMTK versions could be considered:

                       ┌───────┬─────────────────┬─────────────────┬─────────────┐
                       │       │ SYSTEM DCMTK    │ LOCAL DCMTK     │ Supported ? │

   Troubleshooting
       What to do if my project finds a different version of DCMTK?

       Remove DCMTK entry from the CMake cache per find_package() documentation.

   FindDevIL
       This module locates the developer's image library.  http://openil.sourceforge.net/

       This module sets:

          IL_LIBRARIES -   the name of the IL library. These include the full path to
                           the core DevIL library. This one has to be linked into the
                           application.
          ILU_LIBRARIES -  the name of the ILU library. Again, the full path. This
                           library is for filters and effects, not actual loading. It
                           doesn't have to be linked if the functionality it provides
                           is not used.
          ILUT_LIBRARIES - the name of the ILUT library. Full path. This part of the
                           library interfaces with OpenGL. It is not strictly needed
                           in applications.
          IL_INCLUDE_DIR - where to find the il.h, ilu.h and ilut.h files.
          IL_FOUND -       this is set to TRUE if all the above variables were set.
                           This will be set to false if ILU or ILUT are not found,
                           even if they are not needed. In most systems, if one
                           library is found all the others are as well. That's the
                           way the DevIL developers release it.

   FindDoxygen
       This module looks for Doxygen and the path to Graphviz's dot

       Doxygen is a documentation generation tool.  Please see http://www.doxygen.org

       This module accepts the following optional variables:

          DOXYGEN_SKIP_DOT       = If true this module will skip trying to find Dot
                                   (an optional component often used by Doxygen)

       This modules defines the following variables:

          DOXYGEN_EXECUTABLE     = The path to the doxygen command.
          DOXYGEN_FOUND          = Was Doxygen found or not?
          DOXYGEN_VERSION        = The version reported by doxygen --version

          DOXYGEN_DOT_EXECUTABLE = The path to the dot program used by doxygen.
          DOXYGEN_DOT_FOUND      = Was Dot found or not?

       For   compatibility   with   older   versions   of   CMake,  the  now-deprecated  variable
       DOXYGEN_DOT_PATH is set to the path  to  the  directory  containing  dot  as  reported  in
       DOXYGEN_DOT_EXECUTABLE.   The  path  may  have  forward slashes even on Windows and is not
       suitable for direct substitution into a Doxyfile.in template.  If you need this value, use
       get_filename_component()  to  compute it from DOXYGEN_DOT_EXECUTABLE directly, and perhaps
       the file(TO_NATIVE_PATH) command to prepare the path for a Doxygen configuration file.

   FindEXPAT
       Find expat

       Find the native EXPAT headers and libraries.

          EXPAT_INCLUDE_DIRS - where to find expat.h, etc.
          EXPAT_LIBRARIES    - List of libraries when using expat.
          EXPAT_FOUND        - True if expat found.

   FindFLEX
       Find flex executable and provides a macro to generate custom build rules

       The module defines the following variables:

          FLEX_FOUND - true is flex executable is found
          FLEX_EXECUTABLE - the path to the flex executable
          FLEX_VERSION - the version of flex
          FLEX_LIBRARIES - The flex libraries
          FLEX_INCLUDE_DIRS - The path to the flex headers

       The minimum required version of flex can be specified  using  the  standard  syntax,  e.g.
       find_package(FLEX 2.5.13)

       If flex is found on the system, the module provides the macro:

          FLEX_TARGET(Name FlexInput FlexOutput
                      [COMPILE_FLAGS <string>]
                      [DEFINES_FILE <string>]
                      )

       which  creates  a  custom  command  to generate the <FlexOutput> file from the <FlexInput>
       file.  If COMPILE_FLAGS option is specified, the next  parameter  is  added  to  the  flex
       command  line.  If flex is configured to output a header file, the DEFINES_FILE option may
       be used to specify its name. Name is an alias used to get details of this custom  command.
       Indeed the macro defines the following variables:

          FLEX_${Name}_DEFINED - true is the macro ran successfully
          FLEX_${Name}_OUTPUTS - the source file generated by the custom rule, an
          alias for FlexOutput
          FLEX_${Name}_INPUT - the flex source file, an alias for ${FlexInput}
          FLEX_${Name}_OUTPUT_HEADER - the header flex output, if any.

       Flex  scanners  oftenly use tokens defined by Bison: the code generated by Flex depends of
       the header generated by Bison.  This module also defines a macro:

          ADD_FLEX_BISON_DEPENDENCY(FlexTarget BisonTarget)

       which adds the required dependency between a scanner and a parser where  <FlexTarget>  and
       <BisonTarget>  are  the  first  parameters  of  respectively  FLEX_TARGET and BISON_TARGET
       macros.

          ====================================================================
          Example:

          find_package(BISON)
          find_package(FLEX)

          BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
          FLEX_TARGET(MyScanner lexer.l  ${CMAKE_CURRENT_BINARY_DIR}/lexer.cpp)
          ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)

           include_directories(${CMAKE_CURRENT_BINARY_DIR})
           add_executable(Foo
              Foo.cc
              ${BISON_MyParser_OUTPUTS}
              ${FLEX_MyScanner_OUTPUTS}
           )
          ====================================================================

   FindFLTK2
       Find the native FLTK2 includes and library

       The following settings are defined

          FLTK2_FLUID_EXECUTABLE, where to find the Fluid tool
          FLTK2_WRAP_UI, This enables the FLTK2_WRAP_UI command
          FLTK2_INCLUDE_DIR, where to find include files
          FLTK2_LIBRARIES, list of fltk2 libraries
          FLTK2_FOUND, Don't use FLTK2 if false.

       The following settings should not be used in general.

          FLTK2_BASE_LIBRARY   = the full path to fltk2.lib
          FLTK2_GL_LIBRARY     = the full path to fltk2_gl.lib
          FLTK2_IMAGES_LIBRARY = the full path to fltk2_images.lib

   FindFLTK
       Find the native FLTK includes and library

       By default FindFLTK.cmake will search for all of the FLTK components and add them  to  the
       FLTK_LIBRARIES variable.

          You can limit the components which get placed in FLTK_LIBRARIES by
          defining one or more of the following three options:

          FLTK_SKIP_OPENGL, set to true to disable searching for opengl and
                            the FLTK GL library
          FLTK_SKIP_FORMS, set to true to disable searching for fltk_forms
          FLTK_SKIP_IMAGES, set to true to disable searching for fltk_images

          FLTK_SKIP_FLUID, set to true if the fluid binary need not be present
                           at build time

       The following variables will be defined:

          FLTK_FOUND, True if all components not skipped were found
          FLTK_INCLUDE_DIR, where to find include files
          FLTK_LIBRARIES, list of fltk libraries you should link against
          FLTK_FLUID_EXECUTABLE, where to find the Fluid tool
          FLTK_WRAP_UI, This enables the FLTK_WRAP_UI command

       The following cache variables are assigned but should not be used.  See the FLTK_LIBRARIES
       variable instead.

          FLTK_BASE_LIBRARY   = the full path to fltk.lib
          FLTK_GL_LIBRARY     = the full path to fltk_gl.lib
          FLTK_FORMS_LIBRARY  = the full path to fltk_forms.lib
          FLTK_IMAGES_LIBRARY = the full path to fltk_images.lib

   FindFreetype
       Locate FreeType library

       This module defines

          FREETYPE_LIBRARIES, the library to link against
          FREETYPE_FOUND, if false, do not try to link to FREETYPE
          FREETYPE_INCLUDE_DIRS, where to find headers.

          This is the concatenation of the paths:
          FREETYPE_INCLUDE_DIR_ft2build
          FREETYPE_INCLUDE_DIR_freetype2

       $FREETYPE_DIR is an environment variable that would correspond to the

          GETTEXT_MSGFMT_EXECUTABLE: the full path to the msgfmt tool.
          GETTEXT_FOUND: True if gettext has been found.
          GETTEXT_VERSION_STRING: the version of gettext found (since CMake 2.8.8)

       Additionally it provides the following macros:

       GETTEXT_CREATE_TRANSLATIONS ( outputFile [ALL] file1 ...  fileN )

          This will create a target "translations" which will convert the
          given input po files into the binary output mo file. If the
          ALL option is used, the translations will also be created when
          building the default target.

       GETTEXT_PROCESS_POT_FILE(  <potfile>  [ALL]  [INSTALL_DESTINATION   <destdir>]   LANGUAGES
       <lang1> <lang2> ...  )

          Process the given pot file to mo files.
          If INSTALL_DESTINATION is given then automatically install rules will
          be created, the language subdirectory will be taken into account
          (by default use share/locale/).
          If ALL is specified, the pot file is processed when building the all traget.
          It creates a custom target "potfile".

       GETTEXT_PROCESS_PO_FILES(  <lang>  [ALL]  [INSTALL_DESTINATION <dir>] PO_FILES <po1> <po2>
       ...  )

          Process the given po files to mo files for the given language.
          If INSTALL_DESTINATION is given then automatically install rules will
          be created, the language subdirectory will be taken into account
          (by default use share/locale/).
          If ALL is specified, the po files are processed when building the all traget.
          It creates a custom target "pofiles".

       NOTE:
          If you wish to use the Gettext library (libintl), use FindIntl.

       $GSL_ROOT_DIR/include/gsl.  The library directory may optionally provide Release and Debug
       folders.  For Unix-like systems, this script  will  use  $GSL_ROOT_DIR/bin/gsl-config  (if
       found) to aid in the discovery GSL.

   Cache Variables
       This  module  may  set  the  following  variables  depending  on  platform and type of GSL

              The  root  directory  of  the  Google  Test  installation  (may  also  be set as an
              environment variable)

       GTEST_MSVC_SEARCH
              If compiling with MSVC, this variable can be set to  MD  or  MT  (the  default)  to
              enable searching a GTest build tree

   Example usage
          enable_testing()
          find_package(GTest REQUIRED)

          add_executable(foo foo.cc)
          target_link_libraries(foo GTest::GTest GTest::Main)

          add_test(AllTestsInFoo foo)

   Deeper integration with CTest
       If you would like each Google test to show up in CTest as a test you may use the following
       macro:

          GTEST_ADD_TESTS(executable extra_args files...)

       executable
              the path to the test executable

       extra_args
              a list of extra arguments to be passed to executable enclosed in quotes (or ""  for
              none)

       files...
              a list of source files to search for tests and test fixtures.  Or AUTO to find them
              from executable target

       However, note that this macro will slow down your tests by running an executable for  each
       test  and test fixture.  You will also have to re-run CMake after adding or removing tests
       or test fixtures.

       Example usage:

          set(FooTestArgs --foo 1 --bar 2)
          add_executable(FooTest FooUnitTest.cc)
          GTEST_ADD_TESTS(FooTest "${FooTestArgs}" AUTO)

   FindGTK2
       FindGTK2.cmake

       This module can find  the  GTK2  widget  libraries  and  several  of  its  other  optional
       components like gtkmm, glade, and glademm.

       NOTE: If you intend to use version checking, CMake 2.6.2 or later is

          required.

       Specify one or more of the following components as you call this find module.  See example
       below.

          gtk
          gtkmm
          glade
          glademm

       The following variables will be defined for your use

          GTK2_INCLUDE_DIRS - All include directories
          GTK2_LIBRARIES - All libraries
          GTK2_TARGETS - All imported targets
          GTK2_DEFINITIONS - Additional compiler flags

          GTK2_VERSION - The version of GTK2 found (x.y.z)
          GTK2_MAJOR_VERSION - The major version of GTK2
          GTK2_MINOR_VERSION - The minor version of GTK2
          GTK2_PATCH_VERSION - The patch version of GTK2

       Optional variables you can define prior to calling this module:

          GTK2_DEBUG - Enables verbose debugging of the module
          GTK2_ADDITIONAL_SUFFIXES - Allows defining additional directories to
                                     search for include files

       ================= Example Usage:

          Call find_package() once, here are some examples to pick from:

          Require GTK 2.6 or later
              find_package(GTK2 2.6 REQUIRED gtk)

          Require GTK 2.10 or later and Glade
              find_package(GTK2 2.10 REQUIRED gtk glade)

          Search for GTK/GTKMM 2.8 or later
              find_package(GTK2 2.8 COMPONENTS gtk gtkmm)

          if(GTK2_FOUND)
             include_directories(${GTK2_INCLUDE_DIRS})
             add_executable(mygui mygui.cc)
             target_link_libraries(mygui ${GTK2_LIBRARIES})
          endif()

   FindGTK
       try to find GTK (and glib) and GTKGLArea

          GTK_INCLUDE_DIR   - Directories to include to use GTK
          GTK_LIBRARIES     - Files to link against to use GTK
          GTK_FOUND         - GTK was found
          GTK_GL_FOUND      - GTK's GL features were found

   FindHDF5
       Find HDF5, a library for reading and writing self describing array data.

       This module invokes the HDF5 wrapper compiler that should  be  installed  alongside  HDF5.
       Depending  upon  the  HDF5  Configuration,  the  wrapper compiler is called either h5cc or
       h5pcc.  If this succeeds, the module will then call the compiler with the  -show  argument
       to see what flags are used when compiling an HDF5 client application.

       The  module  will  optionally  accept  the  COMPONENTS  argument.   If  no  COMPONENTS are
       specified, then the find module will default to finding only the HDF5 C library.   If  one
       or  more  COMPONENTS  are specified, the module will attempt to find the language bindings
       for the specified components.  The only valid components are  C,  CXX,  Fortran,  HL,  and
       Fortran_HL.  If the COMPONENTS argument is not given, the module will attempt to find only
       the C bindings.

       On UNIX systems, this module will read the variable HDF5_USE_STATIC_LIBRARIES to determine
       whether  or  not  to  prefer  a  static  link  to  a dynamic link for HDF5 and all of it's
       dependencies.  To use this feature, make sure that the HDF5_USE_STATIC_LIBRARIES  variable
       is set before the call to find_package.

       To  provide the module with a hint about where to find your HDF5 installation, you can set
       the environment variable HDF5_ROOT.  The Find module will then  look  in  this  path  when
       searching for HDF5 executables, paths, and libraries.

       Both  the  serial  and  parallel  HDF5  wrappers are considered and the first directory to
       contain either one will be used.  In the event that both appear in the same directory  the
       serial  version  is  preferentially selected. This behavior can be reversed by setting the
       variable HDF5_PREFER_PARALLEL to true.

       In addition to finding the includes and libraries  required  to  compile  an  HDF5  client
       application,  this  module  also  makes  an  effort  to find tools that come with the HDF5
       distribution that may be useful for regression testing.

       This module will define the following variables:

          HDF5_INCLUDE_DIRS - Location of the hdf5 includes
          HDF5_INCLUDE_DIR - Location of the hdf5 includes (deprecated)
          HDF5_DEFINITIONS - Required compiler definitions for HDF5
          HDF5_C_LIBRARIES - Required libraries for the HDF5 C bindings.
          HDF5_CXX_LIBRARIES - Required libraries for the HDF5 C++ bindings
          HDF5_Fortran_LIBRARIES - Required libraries for the HDF5 Fortran bindings
          HDF5_HL_LIBRARIES - Required libraries for the HDF5 high level API
          HDF5_Fortran_HL_LIBRARIES - Required libraries for the high level Fortran
                                      bindings.
          HDF5_LIBRARIES - Required libraries for all requested bindings
          HDF5_FOUND - true if HDF5 was found on the system
          HDF5_VERSION - HDF5 version in format Major.Minor.Release
          HDF5_LIBRARY_DIRS - the full set of library directories
          HDF5_IS_PARALLEL - Whether or not HDF5 was found with parallel IO support
          HDF5_C_COMPILER_EXECUTABLE - the path to the HDF5 C wrapper compiler
          HDF5_CXX_COMPILER_EXECUTABLE - the path to the HDF5 C++ wrapper compiler
          HDF5_Fortran_COMPILER_EXECUTABLE - the path to the HDF5 Fortran wrapper compiler
          HDF5_DIFF_EXECUTABLE - the path to the HDF5 dataset comparison tool

   FindHg
       Extract information from a mercurial working copy.

       The module defines the following variables:

          HG_EXECUTABLE - path to mercurial command line client (hg)
          HG_FOUND - true if the command line client was found
          HG_VERSION_STRING - the version of mercurial found

       If the command line client executable is found the following macro is defined:

          HG_WC_INFO(<dir> <var-prefix>)

       Hg_WC_INFO extracts information of a mercurial working copy at  a  given  location.   This
       macro defines the following variables:

          <var-prefix>_WC_CHANGESET - current changeset
          <var-prefix>_WC_REVISION - current revision

       Example usage:

          find_package(Hg)
          if(HG_FOUND)
            message("hg found: ${HG_EXECUTABLE}")
            HG_WC_INFO(${PROJECT_SOURCE_DIR} Project)
            message("Current revision is ${Project_WC_REVISION}")
            message("Current changeset is ${Project_WC_CHANGESET}")
          endif()

   FindHSPELL

       It defines:

          HTML_HELP_COMPILER     : full path to the Compiler (hhc.exe)
          HTML_HELP_INCLUDE_PATH : include path to the API (htmlhelp.h)
          HTML_HELP_LIBRARY      : full path to the library (htmlhelp.lib)

   FindIce
       Find the ZeroC Internet Communication Engine (ICE) programs, libraries and datafiles.

       This  module  supports  multiple  components.   Components  can  include  any  of: Freeze,
       Glacier2, Ice, IceBox, IceDB, IceGrid, IcePatch, IceSSL,  IceStorm,  IceUtil,  IceXML,  or

       Ice component libraries are reported in:

          Ice_<C>_FOUND - ON if component was found
          Ice_<C>_LIBRARIES - libraries for component

       Note that <C> is the uppercased name of the component.

       This module reads hints about search results from:

          Ice_HOME - the root of the Ice installation

       The  environment  variable  ICE_HOME  may  also  be  used;  the  Ice_HOME  variable  takes
       precedence.

       The following cache variables may also be set:

          Ice_<P>_EXECUTABLE - the path to executable <P>
          Ice_INCLUDE_DIR - the directory containing the Ice headers
          Ice_SLICE_DIR - the directory containing the Ice slice interface
                          definitions
          Ice_<C>_LIBRARY - the library for component <C>

       NOTE:
          In most cases none of the above variables will require  setting,  unless  multiple  Ice
          versions are available and a specific version is required.  On Windows, the most recent
          version of Ice will be found through the registry.  On Unix, the programs, headers  and
          libraries  will  usually  be  in  standard  locations,  but Ice_SLICE_DIRS might not be
          automatically  detected  (commonly  known  locations  are  searched).   All  the  other
          variables  are  defaulted  using  Ice_HOME,  if set.  It's possible to set Ice_HOME and
          selectively specify alternative locations for  the  other  components;  this  might  be
          required  for e.g. newer versions of Visual Studio if the heuristics are not sufficient
          to identify the correct programs and libraries for the specific Visual Studio version.

       Other variables one may set to control this module are:

          Ice_DEBUG - Set to ON to enable debug output from FindIce.

   FindIcotool
       Find icotool

       This module looks for icotool.  This module defines the following values:

          ICOTOOL_EXECUTABLE: the full path to the icotool tool.
          ICOTOOL_FOUND: True if icotool has been found.
          ICOTOOL_VERSION_STRING: the version of icotool found.

   FindImageMagick
       Find the ImageMagick binary suite.

       This module will search for a set of ImageMagick tools  specified  as  components  in  the
       FIND_PACKAGE call.  Typical components include, but are not limited to (future versions of
       ImageMagick might have additional components not listed here):

          animate
          compare
          composite
          conjure
          convert
          display
          identify
          import
          mogrify
          montage
          stream

       If no component is specified in the FIND_PACKAGE call,  then  it  only  searches  for  the
       ImageMagick executable directory.  This code defines the following variables:

          ImageMagick_FOUND                  - TRUE if all components are found.
          ImageMagick_EXECUTABLE_DIR         - Full path to executables directory.
          ImageMagick_<component>_FOUND      - TRUE if <component> is found.
          ImageMagick_<component>_EXECUTABLE - Full path to <component> executable.
          ImageMagick_VERSION_STRING         - the version of ImageMagick found
                                               (since CMake 2.8.8)

       ImageMagick_VERSION_STRING will not work for old versions like 5.2.3.

       There are also components for the following ImageMagick APIs:

          Magick++
          MagickWand
          MagickCore

       For these components the following variables are set:

          ImageMagick_FOUND                    - TRUE if all components are found.
          ImageMagick_INCLUDE_DIRS             - Full paths to all include dirs.
          ImageMagick_LIBRARIES                - Full paths to all libraries.
          ImageMagick_<component>_FOUND        - TRUE if <component> is found.
          ImageMagick_<component>_INCLUDE_DIRS - Full path to <component> include dirs.
          ImageMagick_<component>_LIBRARIES    - Full path to <component> libraries.

       Example Usages:

          find_package(ImageMagick)
          find_package(ImageMagick COMPONENTS convert)
          find_package(ImageMagick COMPONENTS convert mogrify display)
          find_package(ImageMagick COMPONENTS Magick++)
          find_package(ImageMagick COMPONENTS Magick++ convert)

       Note that the standard FIND_PACKAGE features are supported (i.e., QUIET, REQUIRED, etc.).

   FindIntl
       Find the Gettext libintl headers and libraries.

       This  module  reports  information  about  the  Gettext  libintl  installation  in several
       variables.  General variables:

          Intl_FOUND - true if the libintl headers and libraries were found
          Intl_INCLUDE_DIRS - the directory containing the libintl headers
          Intl_LIBRARIES - libintl libraries to be linked

       The following cache variables may also be set:

          Intl_INCLUDE_DIR - the directory containing the libintl headers
          Intl_LIBRARY - the libintl library (if any)

       NOTE:
          On some platforms, such as Linux with GNU libc, the gettext functions  are  present  in
          the  C  standard  library and libintl is not required.  Intl_LIBRARIES will be empty in
          this case.

       NOTE:
          If you wish to use the Gettext tools (msgmerge, msgfmt, etc.), use FindGettext.

   FindITK
       This module no longer exists.

       This module existed in versions of CMake prior to 3.1, but  became  only  a  thin  wrapper
       around   find_package(ITK   NO_MODULE)   to   provide  compatibility  for  projects  using
       long-outdated  conventions.   Now  find_package(ITK)  will  search   for   ITKConfig.cmake
       directly.

   FindJasper
       Try to find the Jasper JPEG2000 library

       Once done this will define

          JASPER_FOUND - system has Jasper
          JASPER_INCLUDE_DIR - the Jasper include directory
          JASPER_LIBRARIES - the libraries needed to use Jasper
          JASPER_VERSION_STRING - the version of Jasper found (since CMake 2.8.8)

   FindJava
       Find Java

       This  module  finds  if  Java  is  installed  and  determines  where the include files and
       libraries are.  The caller may set variable  JAVA_HOME  to  specify  a  Java  installation
       prefix explicitly.

       Specify  one or more of the following components as you call this find module. See example
       below.

          Java_VERSION_MINOR        = The minor version of the package found.
          Java_VERSION_PATCH        = The patch version of the package found.
          Java_VERSION_TWEAK        = The tweak version of the package found (after '_')

       The minimum required version of Java can be specified using  the  standard  CMake  syntax,
       e.g.  find_package(Java 1.5)

       NOTE:  ${Java_VERSION} and ${Java_VERSION_STRING} are not guaranteed to be identical.  For
       example some java version may return: Java_VERSION_STRING = 1.5.0_17  and  Java_VERSION  =
       1.5.0.17

       another  example is the Java OEM, with: Java_VERSION_STRING = 1.6.0-oem and Java_VERSION =
       1.6.0

       For these components the following variables are set:

          Java_FOUND                    - TRUE if all components are found.
          Java_INCLUDE_DIRS             - Full paths to all include dirs.

       KDE3_AUTOMOC(file1 ...  fileN)

          Call this if you want to have automatic moc file handling.
          This means if you include "foo.moc" in the source file foo.cpp
          a moc file for the header foo.h will be created automatically.
          You can set the property SKIP_AUTOMAKE using set_source_files_properties()
          to exclude some files in the list from being processed.

       KDE3_ADD_MOC_FILES(SRCS_VAR file1 ...  fileN )

          If you don't use the KDE3_AUTOMOC() macro, for the files
          listed here moc files will be created (named "foo.moc.cpp")

       KDE3_ADD_DCOP_SKELS(SRCS_VAR header1.h ...  headerN.h )

          Use this to generate DCOP skeletions from the listed headers.

       KDE3_ADD_DCOP_STUBS(SRCS_VAR header1.h ...  headerN.h )

          Use this to generate DCOP stubs from the listed headers.

       KDE3_ADD_UI_FILES(SRCS_VAR file1.ui ...  fileN.ui )

          Use this to add the Qt designer ui files to your application/library.

       KDE3_ADD_KCFG_FILES(SRCS_VAR file1.kcfgc ...  fileN.kcfgc )

          Use this to add KDE kconfig compiler files to your application/library.

       KDE3_INSTALL_LIBTOOL_FILE(target)

          This will create and install a simple libtool file for the given target.

       KDE3_ADD_EXECUTABLE(name file1 ...  fileN )

          Currently identical to add_executable(), may provide some advanced
          features in the future.

       KDE3_ADD_KPART(name [WITH_PREFIX] file1 ...  fileN )

          Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
          If WITH_PREFIX is given, the resulting plugin will have the prefix "lib",
          otherwise it won't.
          It creates and installs an appropriate libtool la-file.

       KDE3_ADD_KDEINIT_EXECUTABLE(name file1 ...  fileN )

          Create a KDE application in the form of a module loadable via kdeinit.
          A library named kdeinit_<name> will be created and a small executable
          which links to it.

       The option KDE3_ENABLE_FINAL to enable all-in-one compilation is no longer supported.

   FindMatlab
       Finds Matlab installations and provides Matlab tools and libraries to cmake.

       This  package  first intention is to find the libraries associated with Matlab in order to
       be able to build Matlab extensions (mex files). It can also be used:

       • run specific commands in Matlab

       • declare Matlab unit test

       • retrieve various information from Matlab (mex extensions, versions and release  queries,
         ...)

       The module supports the following components:

       • MX_LIBRARY and ENG_LIBRARY respectively the MX and ENG libraries of Matlab

       • MAIN_PROGRAM the Matlab binary program.

       NOTE:
          The  version  given to the find_package() directive is the Matlab version, which should
          not   be   confused   with   the   Matlab    release    name    (eg.    R2014).     The
          matlab_get_version_from_release_name() and matlab_get_release_name_from_version() allow
          a mapping from the release name to the version.

       The variable Matlab_ROOT_DIR may be specified in order to give the  path  of  the  desired
       Matlab version. Otherwise, the behaviour is platform specific:

       • Windows: The installed versions of Matlab are retrieved from the Windows registry

       • OS X: The installed versions of Matlab are given by the MATLAB paths in /Application. If
         no such application is found, it falls back to the one that might be accessible from the
         PATH.

       • Unix: The desired Matlab should be accessible from the PATH.

       Additional information is provided when MATLAB_FIND_DEBUG is set.  When a Matlab binary is
       found automatically and the MATLAB_VERSION is not  given,  the  version  is  queried  from
       Matlab directly.  On Windows, it can make a window running Matlab appear.

       The  mapping of the release names and the version of Matlab is performed by defining pairs
       (name, version).  The variable MATLAB_ADDITIONAL_VERSIONS may be provided before the  call
       to the find_package() in order to handle additional versions.

       A  Matlab  scripts  can  be added to the set of tests using the matlab_add_unit_test(). By
       default, the Matlab unit test framework will be used (>= 2013a) to run  this  script,  but
       regular .m files returning an exit code can be used as well (0 indicating a success).

   Module Input Variables
       Users or projects may set the following variables to configure the module behaviour:

       Matlab_MEX_COMPILER
              the  mex  compiler  of Matlab. Currently not used.  Available only if the component
              MEX_COMPILER is asked

   Cached variables
       Matlab_MEX_EXTENSION

       Matlab_ROOT_DIR
              the location of the root of the Matlab installation found. If this value is changed
              by the user, the result variables are recomputed.

   Provided macros
       matlab_get_version_from_release_name()
              returns the version from the release name

       matlab_get_release_name_from_version()
              returns the release name from the Matlab version

   Provided functions
       matlab_add_mex()
              adds a target compiling a MEX file.

       matlab_add_unit_test()
              adds a Matlab unit test file as a test to the project.

       matlab_extract_all_installed_versions_from_registry()
              parses  the  registry for all Matlab versions. Available on Windows only.  The part
              of the registry parsed is dependent on the host processor

       matlab_get_all_valid_matlab_roots_from_registry()
              returns all the possible Matlab paths, according to a previously given  list.  Only
              the existing/accessible paths are kept. This is mainly useful for the searching all
              possible Matlab installation.

       matlab_get_mex_suffix()
              returns the suffix to be used for the mex files (platform/architecture dependant)

       matlab_get_version_from_matlab_run()
              returns the version of Matlab, given the full directory of the Matlab program.

   Known issues
       Symbol clash in a MEX target
              By  default,  every  symbols  inside  a  MEX  file   defined   with   the   command
              matlab_add_mex()  have  hidden  visibility, except for the entry point. This is the
              default behaviour of the MEX compiler, which lowers the risk  of  symbol  collision
              between  the libraries shipped with Matlab, and the libraries to which the MEX file
              is linking to. This is also the default on Windows platforms.

              However, this is not sufficient in certain case, where for instance your  MEX  file
              is  linking  against  libraries  that  are  already loaded by Matlab, even if those
              libraries have different SONAMES.  A possible solution is to hide  the  symbols  of
              the  libraries  to  which the MEX target is linking to. This can be achieved in GNU
              GCC compilers with the linker option -Wl,--exclude-libs,ALL.

       Tests using GPU resources
              in case your MEX file is using the GPU and in order to be able to run unit tests on
              this  MEX file, the GPU resources should be properly released by Matlab. A possible
              solution is to make Matlab aware of the use of the GPU resources  in  the  session,
              which can be performed by a command such as D = gpuDevice() at the beginning of the
              test script (or via a fixture).

              The  root  folder  of  the  Matlab  installation.  If  set  before  the   call   to
              find_package(),  the  module will look for the components in that path. If not set,
              then an automatic search of Matlab will be performed. If set, it should point to  a
              valid version of Matlab.

       MATLAB_FIND_DEBUG
              If set, the lookup of Matlab and the intermediate configuration steps are outputted
              to the console.

       MATLAB_ADDITIONAL_VERSIONS
              If set, specifies additional versions of  Matlab  that  may  be  looked  for.   The
              variable  should  be  a  list  of  strings,  organised by pairs of release name and
              versions, such as follows:

                 set(MATLAB_ADDITIONAL_VERSIONS
                     "release_name1=corresponding_version1"
                     "release_name2=corresponding_version2"
                     ...
                     )

              Example:

                 set(MATLAB_ADDITIONAL_VERSIONS
                     "R2013b=8.2"
                     "R2013a=8.1"
                     "R2012b=8.0")

              The order of entries in this list matters  when  several  versions  of  Matlab  are
              installed. The priority is set according to the ordering in this list.

       matlab_get_version_from_release_name
              Returns the version of Matlab (17.58) from a release name (R2017k)

       matlab_get_release_name_from_version
              Returns the release name (R2017k) from the version of Matlab (17.58)

       matlab_extract_all_installed_versions_from_registry
              This  function  parses  the  registry  and  founds  the  Matlab  versions  that are
              installed. The found versions are returned in matlab_versions.  Set win64  to  TRUE
              if the 64 bit version of Matlab should be looked for The returned list contains all
              versions under HKLM\\SOFTWARE\\Mathworks\\MATLAB or an empty list in case an  error
              occurred (or nothing found).

              NOTE:
                 Only  the  versions  are  provided.  No  check is made over the existence of the
                 installation referenced in the registry,

       matlab_get_all_valid_matlab_roots_from_registry
              Populates the Matlab root with valid versions of Matlab.  The returned matlab_roots
              is organized in pairs (version_number,matlab_root_path).

                 matlab_get_all_valid_matlab_roots_from_registry(
                     matlab_versions
                     matlab_roots)

              matlab_versions

       matlab_get_mex_suffix
              Returns the extension of the mex files (the suffixes).  This function should not be
              called before the appropriate Matlab root has been found.

                 matlab_get_mex_suffix(
                     matlab_root
                     mex_suffix)

              matlab_root
                     the root of the Matlab installation

              mex_suffix
                     the variable name in which the suffix will be returned.

       matlab_get_version_from_matlab_run
              This function runs Matlab program specified on arguments and extracts its version.

                 matlab_get_version_from_matlab_run(
                     matlab_binary_path
                     matlab_list_versions)

              matlab_binary_path
                     the location of the matlab binary executable

              matlab_list_versions

       matlab_add_unit_test
              Adds a Matlab unit test to the test set of cmake/ctest.  This command requires  the
              component MAIN_PROGRAM.  The unit test uses the Matlab unittest framework (default,
              available starting Matlab 2013b+) except if  the  option  NO_UNITTEST_FRAMEWORK  is
              given.

              The  function  expects  one  Matlab  test  script  file  to  be given.  In the case
              NO_UNITTEST_FRAMEWORK is given, the unittest script file should contain the  script
              to be run, plus an exit command with the exit value. This exit value will be passed
              to the ctest framework (0 success, non 0 failure). Additional arguments accepted by
              add_test() can be passed through TEST_ARGS (eg. CONFIGURATION <config> ...).

                 matlab_add_unit_test(
                     NAME <name>
                     UNITTEST_FILE matlab_file_containing_unittest.m
                     [UNITTEST_PRECOMMAND matlab_command_to_run]
                     [TIMEOUT timeout]
                     [ADDITIONAL_PATH path1 [path2 ...]]
                     [MATLAB_ADDITIONAL_STARTUP_OPTIONS option1 [option2 ...]]
                     [TEST_ARGS arg1 [arg2 ...]]
                     [NO_UNITTEST_FRAMEWORK]
                     )

              The function arguments are:

              NAME   name of the unittest in ctest.

              UNITTEST_FILE
                     the matlab unittest file. Its path will be automatically added to the Matlab
                     path.

              UNITTEST_PRECOMMAND
                     Matlab script command to be ran before the file containing the test (eg. GPU
                     device initialisation based on CMake variables).

              TIMEOUT
                     the test timeout in seconds. Defaults to 180 seconds as the Matlab unit test
                     may hang.

              ADDITIONAL_PATH
                     a list of paths to add to the Matlab path prior to running the unit test.

              MATLAB_ADDITIONAL_STARTUP_OPTIONS
                     a list of additional option in order to run Matlab from the command line.

              TEST_ARGS
                     Additional options provided to the add_test command. These options are added
                     to the default options (eg. "CONFIGURATIONS Release")

              NO_UNITTEST_FRAMEWORK
                     when  set,  indicates that the test should not use the unittest framework of
                     Matlab (available for versions >= R2013a).

       matlab_add_mex
              Adds a Matlab MEX target.  This  commands  compiles  the  given  sources  with  the
              current  tool-chain  in order to produce a MEX file. The final name of the produced
              output may be specified, as well as additional link libraries, and a  documentation
              entry  for  the  MEX  file.  Remaining  arguments  of  the  call  are passed to the
              add_library() command.

                 matlab_add_mex(
                     NAME <name>
                     SRC src1 [src2 ...]
                     [OUTPUT_NAME output_name]
                     [DOCUMENTATION file.txt]
                     [LINK_TO target1 target2 ...]
                     [...]
                 )

              NAME   name of the target.

              SRC    list of tje source files.

              LINK_TO
                     a list of additional link dependencies.   The  target  links  to  libmex  by
                     default. If Matlab_MX_LIBRARY is defined, it also links to libmx.

              OUTPUT_NAME
                     if  given,  overrides  the default name. The default name is the name of the
                     target without any prefix and with Matlab_MEX_EXTENSION suffix.

              DOCUMENTATION
                     if given, the file file.txt will be considered as  being  the  documentation
                     file  for the MEX file. This file is copied into the same folder without any
                     processing, with the same name as the final mex file, and with extension .m.
                     In  that  case,  typing  help  <name>  in  Matlab  prints  the documentation
                     contained in this file.

              The documentation file is not processed and should be in the following format:

                 % This is the documentation
                 function ret = mex_target_output_name(input1)

   FindMPI
       Find a Message Passing Interface (MPI) implementation

       The  Message  Passing  Interface  (MPI)  is  a  library  used  to  write  high-performance
       distributed-memory  parallel applications, and is typically deployed on a cluster.  MPI is
       a standard interface (defined by  the  MPI  forum)  for  which  many  implementations  are
       available.   All of them have somewhat different include paths, libraries to link against,
       etc., and this module tries to smooth out those differences.

       === Variables ===

       This module will set the following variables per language in your project, where <lang> is
       one of C, CXX, or Fortran:

          MPI_<lang>_FOUND           TRUE if FindMPI found MPI flags for <lang>
          MPI_<lang>_COMPILER        MPI Compiler wrapper for <lang>
          MPI_<lang>_COMPILE_FLAGS   Compilation flags for MPI programs
          MPI_<lang>_INCLUDE_PATH    Include path(s) for MPI header
          MPI_<lang>_LINK_FLAGS      Linking flags for MPI programs
          MPI_<lang>_LIBRARIES       All libraries to link MPI programs against

       Additionally,  FindMPI  sets  the  following  variables  for running MPI programs from the
       command line:

          MPIEXEC                    Executable for running MPI programs
          MPIEXEC_NUMPROC_FLAG       Flag to pass to MPIEXEC before giving
                                     it the number of processors to run on
          MPIEXEC_PREFLAGS           Flags to pass to MPIEXEC directly
                                     before the executable to run.
          MPIEXEC_POSTFLAGS          Flags to pass to MPIEXEC after other flags

       === Usage ===

       To  use  this  module,  simply  call  FindMPI  from  a   CMakeLists.txt   file,   or   run
       find_package(MPI), then run CMake.  If you are happy with the auto- detected configuration
       for your language, then you're done.  If not, you have two options:

          1. Set MPI_<lang>_COMPILER to the MPI wrapper (mpicc, etc.) of your
             choice and reconfigure.  FindMPI will attempt to determine all the
             necessary variables using THAT compiler's compile and link flags.
          2. If this fails, or if your MPI implementation does not come with
             a compiler wrapper, then set both MPI_<lang>_LIBRARIES and
             MPI_<lang>_INCLUDE_PATH.  You may also set any other variables
             listed above, but these two are required.  This will circumvent
             autodetection entirely.

       When configuration is successful, MPI_<lang>_COMPILER will be set to the compiler  wrapper
       for  <lang>,  if  it was found.  MPI_<lang>_FOUND and other variables above will be set if
       any MPI implementation was found for <lang>, regardless of whether a compiler was found.

       When using MPIEXEC to execute MPI applications,  you  should  typically  use  all  of  the
       MPIEXEC flags as follows:

          ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS
            ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS

       where PROCS is the number of processors on which to execute the program, EXECUTABLE is the
       MPI program, and ARGS are the arguments to pass to the MPI program.

       === Backward Compatibility ===

       For backward compatibility with older versions of FindMPI, these variables  are  set,  but
       deprecated:

          MPI_FOUND           MPI_COMPILER        MPI_LIBRARY
          MPI_COMPILE_FLAGS   MPI_INCLUDE_PATH    MPI_EXTRA_LIBRARY
          MPI_LINK_FLAGS      MPI_LIBRARIES

       In new projects, please use the MPI_<lang>_XXX equivalents.

   FindOpenAL
       Locate  OpenAL  This  module  defines OPENAL_LIBRARY OPENAL_FOUND, if false, do not try to
       link to OpenAL OPENAL_INCLUDE_DIR, where to find the headers

       $OPENALDIR is an environment variable that would correspond to the

       Created by Eric Wing.  This was influenced by the FindSDL.cmake module.

   FindOpenCL
       Try to find OpenCL

       Once done this will define:

          OpenCL_FOUND          - True if OpenCL was found
          OpenCL_INCLUDE_DIRS   - include directories for OpenCL
          OpenCL_LIBRARIES      - link against this library to use OpenCL
          OpenCL_VERSION_STRING - Highest supported OpenCL version (eg. 1.2)
          OpenCL_VERSION_MAJOR  - The major version of the OpenCL implementation
          OpenCL_VERSION_MINOR  - The minor version of the OpenCL implementation

       The module will also define two cache variables:

          OpenCL_INCLUDE_DIR    - the OpenCL include directory
          OpenCL_LIBRARY        - the path to the OpenCL library

   FindOpenGL
       FindModule for OpenGL and GLU.

   Result Variables
       This module sets the following variables:

       OPENGL_FOUND
              True, if the system has OpenGL.

       OPENGL_XMESA_FOUND
              True, if the system has XMESA.

       OPENGL_GLU_FOUND
              True, if the system has GLU.

       OPENGL_INCLUDE_DIR
              Path to the OpenGL include directory.

       OPENGL_LIBRARIES
              Paths to the OpenGL and GLU libraries.

              Path to the OpenGL library.

       OPENGL_glu_LIBRARY
              Path to the GLU library.

   OSX Specific
       On OSX default to using the framework version of OpenGL. People will have  to  change  the
       cache values of OPENGL_glu_LIBRARY and OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX.

   FindOpenMP
       Finds OpenMP support

       This  module can be used to detect OpenMP support in a compiler.  If the compiler supports
       OpenMP, the flags required to compile with OpenMP support are returned  in  variables  for
       the  different  languages.   The  variables  may  be empty if the compiler does not need a
       special flag to support OpenMP.

       The following variables are set:

          OpenMP_C_FLAGS - flags to add to the C compiler for OpenMP support
          OpenMP_CXX_FLAGS - flags to add to the CXX compiler for OpenMP support
          OpenMP_Fortran_FLAGS - flags to add to the Fortran compiler for OpenMP support
          OPENMP_FOUND - true if openmp is detected

       Supported compilers can be found at http://openmp.org/wp/openmp-compilers/

       whatever additional COMPONENTS (nodekits) that you specify.

          See http://www.openscenegraph.org

       NOTE:  To  use  this  module  effectively  you  must  either  require  CMake >= 2.6.3 with
       cmake_minimum_required(VERSION  2.6.3)  or  download  and   place   FindOpenThreads.cmake,
       Findosg_functions.cmake,    Findosg.cmake,    and    Find<etc>.cmake   files   into   your
       CMAKE_MODULE_PATH.

                                            automatically

       The following environment variables are also  respected  for  finding  the  OSG  and  it's
       various components.  CMAKE_PREFIX_PATH can also be used for this (see find_library() CMake
       documentation).

       OSG_ROOT

       [CMake 2.8.10]: The CMake variable OSG_DIR can now be used as well to influence detection,
       instead of needing to specify an environment variable.

       This module defines the following output variables:

          OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found?

          OPENSCENEGRAPH_VERSION - The version of the OSG which was found

          OPENSCENEGRAPH_INCLUDE_DIRS - Where to find the headers

   FindOpenThreads
       OpenThreads   is   a   C++  based  threading  library.   Its  largest  userbase  seems  to
       OpenSceneGraph so you might notice I accept OSGDIR as an  environment  path.   I  consider
       this part of the Findosg* suite used to find OpenSceneGraph components.  Each component is
       separate and you must opt in to each module.

       Locate OpenThreads This module defines OPENTHREADS_LIBRARY OPENTHREADS_FOUND, if false, do
       not try to link to OpenThreads OPENTHREADS_INCLUDE_DIR, where to find the headers

       $OPENTHREADS_DIR  is  an  environment  variable  that  would correspond to the ./configure
       --prefix=$OPENTHREADS_DIR used in building osg.

       [CMake 2.8.10]: The CMake variables OPENTHREADS_DIR or OSG_DIR can now be used as well  to
       influence detection, instead of needing to specify an environment variable.

   FindosgAnimation
       This is part of the Findosg* suite used to find OpenSceneGraph components.  Each component

       allow you control over your own system piece by piece in case  you  need  to  opt  out  of
       certain  components  or  change the Find behavior for a particular module (perhaps because
       the default FindOpenGL.cmake module doesn't work with your system as an example).  If  you
       want   to   use   a   more   convenient   module   that   includes   everything,  use  the
       FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

       allow  you  control  over  your  own  system piece by piece in case you need to opt out of
       certain components or change the Find behavior for a particular  module  (perhaps  because
       the  default FindOpenGL.cmake module doesn't work with your system as an example).  If you
       want  to  use   a   more   convenient   module   that   includes   everything,   use   the
       FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

       Locate osgWidget This module defines

       OSGWIDGET_FOUND  -  Was osgWidget found? OSGWIDGET_INCLUDE_DIR - Where to find the headers
       OSGWIDGET_LIBRARIES - The libraries to link for osgWidget (use this)

       OSGWIDGET_LIBRARY - The osgWidget library OSGWIDGET_LIBRARY_DEBUG -  The  osgWidget  debug
       library

       $OSGDIR is an environment variable that would correspond to the

       FindosgWidget.cmake tweaked from Findosg* suite as created by Eric Wing.

   FindPackageHandleStandardArgs
       This  module  provides  a  function  intended  to  be  used  in  Find Modules implementing
       find_package(<PackageName>) calls.  It handles the  REQUIRED,  QUIET  and  version-related
       arguments of find_package.  It also sets the <PackageName>_FOUND variable.  The package is
       considered found if all variables listed contain valid results, e.g.  valid filepaths.

       find_package_handle_standard_args
              There are two signatures:

                 find_package_handle_standard_args(<PackageName>
                   (DEFAULT_MSG|<custom-failure-message>)
                   <required-var>...
                   )

                 find_package_handle_standard_args(<PackageName>
                   [FOUND_VAR <result-var>]
                   [REQUIRED_VARS <required-var>...]
                   [VERSION_VAR <version-var>]
                   [HANDLE_COMPONENTS]
                   [CONFIG_MODE]
                   [FAIL_MESSAGE <custom-failure-message>]
                   )

              The <PackageName>_FOUND  variable  will  be  set  to  TRUE  if  all  the  variables
              <required-var>...  are  valid and any optional constraints are satisfied, and FALSE
              otherwise.  A success or failure message may be displayed based on the results  and
              on whether the REQUIRED and/or QUIET option was given to the find_package() call.

              The options are:

              (DEFAULT_MSG|<custom-failure-message>)
                     In the simple signature this specifies the failure message.  Use DEFAULT_MSG
                     to ask for a default message to be computed (recommended).  Not valid in the
                     full signature.

              FOUND_VAR <result-var>
                     Obsolete.   Specifies  either  <PackageName>_FOUND or <PACKAGENAME>_FOUND as
                     the result variable.  This exists only for compatibility with older versions
                     of  CMake and is now ignored.  Result variables of both names are always set
                     for compatibility.

              REQUIRED_VARS <required-var>...
                     Specify the variables which are required for this  package.   These  may  be
                     named  in  the  generated failure message asking the user to set the missing
                     variable values.  Therefore these should typically be cache entries such  as
                     FOO_LIBRARY and not output variables like FOO_LIBRARIES.

              VERSION_VAR <version-var>
                     Specify  the  name  of a variable that holds the version of the package that
                     has been found.  This version will  be  checked  against  the  (potentially)
                     specified  required  version given to the find_package() call, including its
                     EXACT option.  The default messages include information about  the  required
                     version  and  the version which has been actually found, both if the version
                     is ok or not.

              HANDLE_COMPONENTS
                     Enable handling of package components.   In  this  case,  the  command  will
                     report  which  components  have  been  found  and which are missing, and the
                     <PackageName>_FOUND variable will be set to FALSE if  any  of  the  required
                     components (i.e. not the ones listed after the OPTIONAL_COMPONENTS option of
                     find_package()) are missing.

              CONFIG_MODE
                     Specify that the  calling  find  module  is  a  wrapper  around  a  call  to
                     find_package(<PackageName>  NO_MODULE).  This implies a VERSION_VAR value of
                     <PackageName>_VERSION.  The command will  automatically  check  whether  the
                     package configuration file was found.

              FAIL_MESSAGE <custom-failure-message>
                     Specify  a  custom  failure  message  instead of using the default generated
                     message.  Not recommended.

       Example for the simple signature:

          find_package_handle_standard_args(LibXml2 DEFAULT_MSG
            LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)

       The  LibXml2  package  is  considered  to   be   found   if   both   LIBXML2_LIBRARY   and
       LIBXML2_INCLUDE_DIR  are  valid.   Then  also  LibXml2_FOUND is set to TRUE.  If it is not
       found and REQUIRED was used, it fails with  a  message(FATAL_ERROR),  independent  whether
       QUIET was used or not.  If it is found, success will be reported, including the content of
       the first <required-var>.  On repeated CMake runs, the same message will  not  be  printed
       again.

       Example for the full signature:

          find_package_handle_standard_args(LibArchive
            REQUIRED_VARS LibArchive_LIBRARY LibArchive_INCLUDE_DIR
            VERSION_VAR LibArchive_VERSION)

       In  this case, the LibArchive package is considered to be found if both LibArchive_LIBRARY
       and LibArchive_INCLUDE_DIR are valid.  Also the version of LibArchive will be  checked  by
       using  the  version  contained in LibArchive_VERSION.  Since no FAIL_MESSAGE is given, the
       default messages will be printed.

       Another example for the full signature:

          find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
          find_package_handle_standard_args(Automoc4  CONFIG_MODE)

       In this case, a FindAutmoc4.cmake module wraps a call to find_package(Automoc4  NO_MODULE)
       and   adds   an   additional   search   directory   for   automoc4.    Then  the  call  to
       find_package_handle_standard_args produces a proper success/failure message.

   FindPackageMessage
       FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")

       This macro is intended to be used in FindXXX.cmake modules files.  It will print a message
       once for each unique find result.  This is useful for telling the user where a package was
       found.  The first argument specifies the name (XXX) of the package.  The  second  argument
       specifies  the message to display.  The third argument lists details about the find result
       so that if they change the message will be displayed again.   The  macro  also  obeys  the
       QUIET argument to the find_package command.

       Example:

          if(X11_FOUND)
            FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
              "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
          else()
           ...
          endif()

   FindPerlLibs
       Find Perl libraries

       This  module  finds  if  PERL  is  installed  and  determines  where the include files and
       libraries are.  It also determines what the name of the library is.  This  code  sets  the
       following variables:

          PERLLIBS_FOUND    = True if perl.h & libperl were found
          PERL_INCLUDE_PATH = path to where perl.h is found
          PERL_LIBRARY      = path to libperl
          PERL_EXECUTABLE   = full path to the perl binary

       The  minimum  required  version  of  Perl can be specified using the standard syntax, e.g.
       find_package(PerlLibs 6.0)

          The following variables are also available if needed
          (introduced after CMake 2.6.4)

          PERL_SITESEARCH    = path to the sitesearch install dir
          PERL_SITELIB       = path to the sitelib install directory
          PERL_VENDORARCH    = path to the vendor arch install directory
          PERL_VENDORLIB     = path to the vendor lib install directory
          PERL_ARCHLIB       = path to the arch lib install directory
          PERL_PRIVLIB       = path to the priv lib install directory
          PERL_EXTRA_C_FLAGS = Compilation flags used to build perl

   FindPerl
       Find perl

       this module looks for Perl

          PERL_EXECUTABLE     - the full path to perl
          PERL_FOUND          - If false, don't attempt to use perl.
          PERL_VERSION_STRING - version of perl found (since CMake 2.8.8)

   FindPHP4
       Find PHP4

       This module finds if PHP4  is  installed  and  determines  where  the  include  files  and
       libraries  are.   It  also determines what the name of the library is.  This code sets the
       following variables:

          PHP4_INCLUDE_PATH       = path to where php.h can be found
          PHP4_EXECUTABLE         = full path to the php4 binary

   FindPhysFS
       Locate PhysFS library This module defines PHYSFS_LIBRARY, the name of the library to  link
       against  PHYSFS_FOUND, if false, do not try to link to PHYSFS PHYSFS_INCLUDE_DIR, where to
       find physfs.h

       $PHYSFSDIR is an environment variable that would correspond to the

       Created by Eric Wing.

   FindPike
       Find Pike

       This module finds if PIKE  is  installed  and  determines  where  the  include  files  and
       libraries  are.   It  also determines what the name of the library is.  This code sets the
       following variables:

          PIKE_INCLUDE_PATH       = path to where program.h is found
          PIKE_EXECUTABLE         = full path to the pike binary

   FindPkgConfig
       A pkg-config module for CMake.

       Finds the pkg-config executable and add the  pkg_check_modules()  and  pkg_search_module()
       commands.

       In  order to find the pkg-config executable, it uses the PKG_CONFIG_EXECUTABLE variable or
       the PKG_CONFIG environment variable first.

       pkg_get_variable
              Retrieves the value of a variable from a package:

                 pkg_get_variable(<RESULT> <MODULE> <VARIABLE>)

              For example:

                 pkg_get_variable(GI_GIRDIR gobject-introspection-1.0 girdir)

       pkg_check_modules
              Checks for all the given modules.

                 pkg_check_modules(<PREFIX> [REQUIRED] [QUIET]
                                   [NO_CMAKE_PATH] [NO_CMAKE_ENVIRONMENT_PATH]
                                   <MODULE> [<MODULE>]*)

              When the REQUIRED argument was set, macros will fail with an error  when  module(s)
              could not be found.

              When the QUIET argument is set, no status messages will be printed.

              By   default,   if   CMAKE_MINIMUM_REQUIRED_VERSION   is   3.1   or  later,  or  if
              PKG_CONFIG_USE_CMAKE_PREFIX_PATH      is      set,      the      CMAKE_PREFIX_PATH,
              CMAKE_FRAMEWORK_PATH, and CMAKE_APPBUNDLE_PATH cache and environment variables will
              be    added    to    pkg-config    search    path.     The    NO_CMAKE_PATH     and
              NO_CMAKE_ENVIRONMENT_PATH  arguments  disable this behavior for the cache variables
              and the environment variables, respectively.

              It sets the following variables:

                 PKG_CONFIG_FOUND          ... if pkg-config executable was found
                 PKG_CONFIG_EXECUTABLE     ... pathname of the pkg-config program
                 PKG_CONFIG_VERSION_STRING ... the version of the pkg-config program found
                                               (since CMake 2.8.8)

              For the following variables two sets of values exist; first one is the  common  one
              and  has  the given PREFIX.  The second set contains flags which are given out when
              pkg-config was called with the --static option.

                 <XPREFIX>_FOUND          ... set to 1 if module(s) exist
                 <XPREFIX>_LIBRARIES      ... only the libraries (w/o the '-l')
                 <XPREFIX>_LIBRARY_DIRS   ... the paths of the libraries (w/o the '-L')
                 <XPREFIX>_LDFLAGS        ... all required linker flags
                 <XPREFIX>_LDFLAGS_OTHER  ... all other linker flags
                 <XPREFIX>_INCLUDE_DIRS   ... the '-I' preprocessor flags (w/o the '-I')
                 <XPREFIX>_CFLAGS         ... all required cflags
                 <XPREFIX>_CFLAGS_OTHER   ... the other compiler flags

                 <XPREFIX> = <PREFIX>        for common case
                 <XPREFIX> = <PREFIX>_STATIC for static linking

              There are some special variables  whose  prefix  depends  on  the  count  of  given
              modules.   When there is only one module, <PREFIX> stays unchanged.  When there are
              multiple modules, the prefix will be changed to <PREFIX>_<MODNAME>:

                 <XPREFIX>_VERSION    ... version of the module
                 <XPREFIX>_PREFIX     ... prefix-directory of the module
                 <XPREFIX>_INCLUDEDIR ... include-dir of the module
                 <XPREFIX>_LIBDIR     ... lib-dir of the module

                 <XPREFIX> = <PREFIX>  when |MODULES| == 1, else
                 <XPREFIX> = <PREFIX>_<MODNAME>

              A <MODULE> parameter can have the following formats:

                 {MODNAME}            ... matches any version
                 {MODNAME}>={VERSION} ... at least version <VERSION> is required
                 {MODNAME}={VERSION}  ... exactly version <VERSION> is required
                 {MODNAME}<={VERSION} ... modules must not be newer than <VERSION>

              Examples

                 pkg_check_modules (GLIB2   glib-2.0)

                 pkg_check_modules (GLIB2   glib-2.0>=2.10)

              Requires at least version 2.10 of glib2 and defines e.g.  GLIB2_VERSION=2.10.3

                 pkg_check_modules (FOO     glib-2.0>=2.10 gtk+-2.0)

              Requires both glib2 and gtk2, and  defines  e.g.   FOO_glib-2.0_VERSION=2.10.3  and
              FOO_gtk+-2.0_VERSION=2.8.20

                 pkg_check_modules (XRENDER REQUIRED xrender)

              Defines for example:

                 XRENDER_LIBRARIES=Xrender;X11``
                 XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp

       pkg_search_module
              Same  as  pkg_check_modules(), but instead it checks for given modules and uses the
              first working one.

                 pkg_search_module(<PREFIX> [REQUIRED] [QUIET]
                                   [NO_CMAKE_PATH] [NO_CMAKE_ENVIRONMENT_PATH]
                                   <MODULE> [<MODULE>]*)

              Examples

                 pkg_search_module (BAR     libxml-2.0 libxml2 libxml>=2)

       PKG_CONFIG_EXECUTABLE
              Path to the pkg-config executable.

       PKG_CONFIG_USE_CMAKE_PREFIX_PATH
              Whether  pkg_check_modules()  and  pkg_search_module()  should  add  the  paths  in
              CMAKE_PREFIX_PATH,   CMAKE_FRAMEWORK_PATH,   and   CMAKE_APPBUNDLE_PATH  cache  and
              environment variables to pkg-config search path.

              If  this  variable  is  not  set,  this  behavior  is   enabled   by   default   if
              CMAKE_MINIMUM_REQUIRED_VERSION is 3.1 or later, disabled otherwise.

   FindPNG
       Find libpng, the official reference library for the PNG image format.

   Imported targets
       This module defines the following IMPORTED target:

       PNG::PNG
              The libpng library, if found.

   Result variables
       This module will set the following variables in your project:

       PNG_INCLUDE_DIRS
              where to find png.h, etc.

       PNG_LIBRARIES
              the libraries to link against to use PNG.

       PNG_DEFINITIONS
              You  should  add_definitons(${PNG_DEFINITIONS}) before compiling code that includes
              png library files.

       PNG_FOUND
              If false, do not try to use PNG.

       PNG_VERSION_STRING
              the version of the PNG library found (since CMake 2.8.8)

   Obsolete variables
       The following variables may also be set, for backwards compatibility:

       PNG_LIBRARY
              where to find the PNG library.

       PNG_INCLUDE_DIR
              where to find the PNG headers (same as PNG_INCLUDE_DIRS)

       Since PNG depends on the ZLib compression library, none  of  the  above  will  be  defined
       unless ZLib can be found.

   FindPostgreSQL
       Find the PostgreSQL installation.

       This module defines

          PostgreSQL_LIBRARIES - the PostgreSQL libraries needed for linking
          PostgreSQL_INCLUDE_DIRS - the directories of the PostgreSQL headers
          PostgreSQL_LIBRARY_DIRS  - the link directories for PostgreSQL libraries
          PostgreSQL_VERSION_STRING - the version of PostgreSQL found (since CMake 2.8.8)

   FindProducer
       Though  Producer  isn't  directly  part  of  OpenSceneGraph,  its primary user is OSG so I
       consider this part of the Findosg* suite used to find OpenSceneGraph  components.   You'll
       notice that I accept OSGDIR as an environment path.

       Each  component  is  separate  and you must opt in to each module.  You must also opt into
       OpenGL (and OpenThreads?) as these modules won't do it for you.   This  is  to  allow  you
       control  over  your  own  system  piece  by  piece  in case you need to opt out of certain
       components or change the Find behavior  for  a  particular  module  (perhaps  because  the
       default FindOpenGL.cmake module doesn't work with your system as an example).  If you want
       to use a more convenient module that includes everything, use the FindOpenSceneGraph.cmake
       instead of the Findosg*.cmake modules.

       Locate  Producer This module defines PRODUCER_LIBRARY PRODUCER_FOUND, if false, do not try
       to link to Producer PRODUCER_INCLUDE_DIR, where to find the headers

       $PRODUCER_DIR is an environment variable that would correspond to the

       Created by Eric Wing.

   FindProtobuf
       Locate and configure the Google Protocol Buffers library.

       The following variables can be set and are optional:

       PROTOBUF_SRC_ROOT_FOLDER
              When compiling with MSVC, if this cache variable is  set  the  protobuf-default  VS

              vsprojects/x64/Debug and vsprojects/x64/Release) will be searched for libraries and
              binaries.

   FindPythonInterp
       Find python interpreter

       This module finds if Python interpreter is installed and determines where the  executables
       are.  This code sets the following variables:

          PYTHONINTERP_FOUND         - Was the Python executable found
          PYTHON_EXECUTABLE          - path to the Python interpreter

          PYTHON_VERSION_STRING      - Python version found e.g. 2.5.2
          PYTHON_VERSION_MAJOR       - Python major version found e.g. 2
          PYTHON_VERSION_MINOR       - Python minor version found e.g. 5
          PYTHON_VERSION_PATCH       - Python patch version found e.g. 2

       The  Python_ADDITIONAL_VERSIONS  variable can be used to specify a list of version numbers
       that should be taken into account when  searching  for  Python.   You  need  to  set  this
       variable before calling find_package(PythonInterp).

       If    calling   both   find_package(PythonInterp)   and   find_package(PythonLibs),   call
       find_package(PythonInterp) first to get the currently active  Python  version  by  default
       with a consistent version of PYTHON_LIBRARIES.

   FindPythonLibs
       Find python libraries

       This  module  finds  if  Python  is  installed  and determines where the include files and
       libraries are.  It also determines what the name of the library is.  This  code  sets  the
       following variables:

          PYTHONLIBS_FOUND           - have the Python libs been found
          PYTHON_LIBRARIES           - path to the python library
          PYTHON_INCLUDE_PATH        - path to where Python.h is found (deprecated)
          PYTHON_INCLUDE_DIRS        - path to where Python.h is found
          PYTHON_DEBUG_LIBRARIES     - path to the debug library (deprecated)
          PYTHONLIBS_VERSION_STRING  - version of the Python libs found (since CMake 2.8.8)

       The  Python_ADDITIONAL_VERSIONS  variable can be used to specify a list of version numbers
       that should be taken into account when  searching  for  Python.   You  need  to  set  this
       variable before calling find_package(PythonLibs).

       If  you'd  like  to  specify  the  installation  of  Python  to use, you should modify the
       following cache variables:

          PYTHON_LIBRARY             - path to the python library
          PYTHON_INCLUDE_DIR         - path to where Python.h is found

       If   calling   both   find_package(PythonInterp)   and   find_package(PythonLibs),    call
       find_package(PythonInterp)  first  to  get  the currently active Python version by default
       with a consistent version of PYTHON_LIBRARIES.

   FindQt3
       Locate Qt include paths and libraries

       This module defines:

          QT_INCLUDE_DIR    - where to find qt.h, etc.
          QT_LIBRARIES      - the libraries to link against to use Qt.
          QT_DEFINITIONS    - definitions to use when
                              compiling code that uses Qt.
          QT_FOUND          - If false, don't try to use Qt.
          QT_VERSION_STRING - the version of Qt found

       If you need the multithreaded version of Qt, set QT_MT_REQUIRED to TRUE

       Also defined, but not for general use are:

          QT_MOC_EXECUTABLE, where to find the moc tool.
          QT_UIC_EXECUTABLE, where to find the uic tool.
          QT_QT_LIBRARY, where to find the Qt library.
          QT_QTMAIN_LIBRARY, where to find the qtmain
           library. This is only required by Qt3 on Windows.

   FindQt4
   Finding and Using Qt4
       This module can be used to find Qt4.  The most important issue is that the  Qt4  qmake  is
       available  via  the  system  path.  This qmake is then used to detect basically everything
       else.  This module defines a number of IMPORTED targets, macros and variables.

       Typical usage could be something like:

          set(CMAKE_AUTOMOC ON)
          set(CMAKE_INCLUDE_CURRENT_DIR ON)
          find_package(Qt4 4.4.3 REQUIRED QtGui QtXml)
          add_executable(myexe main.cpp)
          target_link_libraries(myexe Qt4::QtGui Qt4::QtXml)

       NOTE:
          When using IMPORTED targets, the qtmain.lib static library is automatically  linked  on
          Windows  for  WIN32  executables.  To disable that globally, set the QT4_NO_LINK_QTMAIN
          variable before finding Qt4. To disable that  for  a  particular  executable,  set  the
          QT4_NO_LINK_QTMAIN target property to TRUE on the executable.

   Qt Build Tools
       Qt  relies  on  some  bundled  tools for code generation, such as moc for meta-object code
       generation,``uic`` for widget layout  and  population,  and  rcc  for  virtual  filesystem
       content  generation.   These  tools  may  be  automatically  invoked  by  cmake(1)  if the
       appropriate conditions are met.  See cmake-qt(7) for more.

   Qt Macros
       In some cases it can be necessary or useful to invoke the Qt build tools in a  more-manual
       way. Several macros are available to add targets for such uses.

          macro QT4_WRAP_CPP(outfiles inputfile ... [TARGET tgt] OPTIONS ...)
                create moc code from a list of files containing Qt class with
                the Q_OBJECT declaration.  Per-directory preprocessor definitions
                are also added.  If the <tgt> is specified, the
                INTERFACE_INCLUDE_DIRECTORIES and INTERFACE_COMPILE_DEFINITIONS from
                the <tgt> are passed to moc.  Options may be given to moc, such as
                those found when executing "moc -help".

          macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
                create code from a list of Qt designer ui files.
                Options may be given to uic, such as those found
                when executing "uic -help"

          macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
                create code from a list of Qt resource files.
                Options may be given to rcc, such as those found
                when executing "rcc -help"

          macro QT4_GENERATE_MOC(inputfile outputfile [TARGET tgt])
                creates a rule to run moc on infile and create outfile.
                Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
                because you need a custom filename for the moc file or something
                similar.  If the <tgt> is specified, the
                INTERFACE_INCLUDE_DIRECTORIES and INTERFACE_COMPILE_DEFINITIONS from
                the <tgt> are passed to moc.

          macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
                Create the interface header and implementation files with the
                given basename from the given interface xml file and add it to
                the list of sources.

                You can pass additional parameters to the qdbusxml2cpp call by setting
                properties on the input file:

                INCLUDE the given file will be included in the generate interface header

                CLASSNAME the generated class is named accordingly

                NO_NAMESPACE the generated class is not wrapped in a namespace

          macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
                Create the interface header and implementation files
                for all listed interface xml files.
                The basename will be automatically determined from the name
                of the xml file.

                The source file properties described for
                QT4_ADD_DBUS_INTERFACE also apply here.

          macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname
                                     [basename] [classname])
                create a dbus adaptor (header and implementation file) from the xml file
                describing the interface, and add it to the list of sources. The adaptor
                forwards the calls to a parent class, defined in parentheader and named
                parentclassname. The name of the generated files will be
                <basename>adaptor.{cpp,h} where basename defaults to the basename of the
                xml file.
                If <classname> is provided, then it will be used as the classname of the
                adaptor itself.

          macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...)
                generate the xml interface file from the given header.
                If the optional argument interfacename is omitted, the name of the
                interface file is constructed from the basename of the header with
                the suffix .xml appended.
                Options may be given to qdbuscpp2xml, such as those found when
                executing "qdbuscpp2xml --help"

          macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ...
                                        ts_files ... OPTIONS ...)
                out: qm_files
                in:  directories sources ts_files
                options: flags to pass to lupdate, such as -extensions to specify
                extensions for a directory scan.
                generates commands to create .ts (vie lupdate) and .qm
                (via lrelease) - files from directories and/or sources. The ts files are
                created and/or updated in the source tree (unless given with full paths).
                The qm files are generated in the build tree.
                Updating the translations can be done by adding the qm_files
                to the source list of your library/executable, so they are
                always updated, or by adding a custom target to control when
                they get updated/generated.

          macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
                out: qm_files
                in:  ts_files
                generates commands to create .qm from .ts - files. The generated
                filenames can be found in qm_files. The ts_files
                must exist and are not updated in any way.

          macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... [TARGET tgt])
                The qt4_automoc macro is obsolete.  Use the CMAKE_AUTOMOC feature instead.
                This macro is still experimental.
                It can be used to have moc automatically handled.
                So if you have the files foo.h and foo.cpp, and in foo.h a
                a class uses the Q_OBJECT macro, moc has to run on it. If you don't
                want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
                #include "foo.moc"
                in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will
                scan all listed files at cmake-time for such included moc files and if it
                finds them cause a rule to be generated to run moc at build time on the
                accompanying header file foo.h.
                If a source file has the SKIP_AUTOMOC property set it will be ignored by
                this macro.
                If the <tgt> is specified, the INTERFACE_INCLUDE_DIRECTORIES and
                INTERFACE_COMPILE_DEFINITIONS from the <tgt> are passed to moc.

          function QT4_USE_MODULES( target [link_type] modules...)
                 This function is obsolete. Use target_link_libraries with IMPORTED targets
                 instead.
                 Make <target> use the <modules> from Qt. Using a Qt module means
                 to link to the library, add the relevant include directories for the
                 module, and add the relevant compiler defines for using the module.
                 Modules are roughly equivalent to components of Qt4, so usage would be
                 something like:
                  qt4_use_modules(myexe Core Gui Declarative)
                 to use QtCore, QtGui and QtDeclarative. The optional <link_type> argument
                 can be specified as either LINK_PUBLIC or LINK_PRIVATE to specify the
                 same argument to the target_link_libraries call.

   IMPORTED Targets
       A  particular  Qt  library may be used by using the corresponding IMPORTED target with the
       target_link_libraries() command:

          target_link_libraries(myexe Qt4::QtGui Qt4::QtXml)

       Using a target in this way causes :cmake(1)` to use the  appropriate  include  directories
       and compile definitions for the target when compiling myexe.

       Targets  are  aware  of  their  dependencies,  so  for example it is not necessary to list
       Qt4::QtCore if another Qt library is listed, and it is not necessary to list Qt4::QtGui if
       Qt4::QtDeclarative  is  listed.  Targets may be tested for existence in the usual way with
       the if(TARGET) command.

       The Qt toolkit may contain both debug and release libraries.   cmake(1)  will  choose  the
       appropriate version based on the build configuration.

   Result Variables
          Below is a detailed list of variables that FindQt4.cmake sets.

       Qt4_FOUND
              If false, don't try to use Qt 4.

       QT_FOUND
              If false, don't try to use Qt. This variable is for compatibility only.

       QT4_FOUND
              If false, don't try to use Qt 4. This variable is for compatibility only.

       QT_VERSION_MAJOR
              The major version of Qt found.

       QT_VERSION_MINOR
              The minor version of Qt found.

       QT_VERSION_PATCH
              The patch version of Qt found.

   FindQt
       Searches for all installed versions of Qt.

       This  should  only be used if your project can work with multiple versions of Qt.  If not,
       you should just directly use FindQt4 or FindQt3.  If multiple versions of Qt are found  on
       the machine, then The user must set the option DESIRED_QT_VERSION to the version they want
       to use.  If only one version of qt is found on the machine, then the DESIRED_QT_VERSION is
       set to that version and the matching FindQt3 or FindQt4 module is included.  Once the user
       sets DESIRED_QT_VERSION, then the FindQt3 or FindQt4 module is included.

       This module can only detect and switch between Qt versions 3 and 4. It cannot  handle  Qt5
       or any later versions.

          QT_REQUIRED if this is set to TRUE then if CMake can
                      not find Qt4 or Qt3 an error is raised
                      and a message is sent to the user.

          DESIRED_QT_VERSION OPTION is created
          QT4_INSTALLED is set to TRUE if qt4 is found.
          QT3_INSTALLED is set to TRUE if qt3 is found.

   FindQuickTime
       Locate  QuickTime  This module defines QUICKTIME_LIBRARY QUICKTIME_FOUND, if false, do not
       try to link to gdal QUICKTIME_INCLUDE_DIR, where to find the headers

       $QUICKTIME_DIR is an environment variable that would correspond to the

       Created by Eric Wing.

   FindRTI
       Try to find M&S HLA RTI libraries

       This module finds if any HLA RTI is installed and locates the standard RTI  include  files
       and libraries.

       RTI  is  a simulation infrastructure standardized by IEEE and SISO.  It has a well defined
       C++ API that assures that simulation applications are  independent  on  a  particular  RTI
       implementation.

   FindRuby
       Find Ruby

       This  module  finds  if  Ruby  is  installed  and  determines  where the include files and
       libraries are.  Ruby 1.8, 1.9, 2.0 and 2.1 are supported.

       The minimum required version of Ruby can be specified  using  the  standard  syntax,  e.g.
       find_package(Ruby 1.8)

       It  also  determines  what  the  name  of  the  library  is.  This code sets the following
       variables:

       RUBY_EXECUTABLE
              full path to the ruby binary

       RUBY_INCLUDE_DIRS
              include dirs to be used when using the ruby library

       RUBY_LIBRARY
              full path to the ruby library

       RUBY_VERSION
              the version of ruby which was found, e.g. "1.8.7"

       RUBY_FOUND
              set to true if ruby ws found successfully

       Also:

       RUBY_INCLUDE_PATH
              same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don't use it

   FindSDL_image
       Locate SDL_image library

       This module defines:

          SDL_IMAGE_LIBRARIES, the name of the library to link against
          SDL_IMAGE_INCLUDE_DIRS, where to find the headers
          SDL_IMAGE_FOUND, if false, do not try to link against
          SDL_IMAGE_VERSION_STRING - human-readable string containing the
                                     version of SDL_image

       For backward compatiblity the following variables are also set:

          SDLIMAGE_LIBRARY (same value as SDL_IMAGE_LIBRARIES)
          SDLIMAGE_INCLUDE_DIR (same value as SDL_IMAGE_INCLUDE_DIRS)
          SDLIMAGE_FOUND (same value as SDL_IMAGE_FOUND)

       $SDLDIR is an environment variable that would correspond to the

       Created by Eric  Wing.   This  was  influenced  by  the  FindSDL.cmake  module,  but  with
       modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc).

   FindSDL_mixer
       Locate SDL_mixer library

       This module defines:

          SDL_MIXER_LIBRARIES, the name of the library to link against
          SDL_MIXER_INCLUDE_DIRS, where to find the headers
          SDL_MIXER_FOUND, if false, do not try to link against
          SDL_MIXER_VERSION_STRING - human-readable string containing the
                                     version of SDL_mixer

       For backward compatiblity the following variables are also set:

          SDLMIXER_LIBRARY (same value as SDL_MIXER_LIBRARIES)
          SDLMIXER_INCLUDE_DIR (same value as SDL_MIXER_INCLUDE_DIRS)
          SDLMIXER_FOUND (same value as SDL_MIXER_FOUND)

       $SDLDIR is an environment variable that would correspond to the

       Created  by  Eric  Wing.   This  was  influenced  by  the  FindSDL.cmake  module, but with
       modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc).

   FindSDL_net
       Locate SDL_net library

       This module defines:

          SDL_NET_LIBRARIES, the name of the library to link against
          SDL_NET_INCLUDE_DIRS, where to find the headers
          SDL_NET_FOUND, if false, do not try to link against
          SDL_NET_VERSION_STRING - human-readable string containing the version of SDL_net

       For backward compatiblity the following variables are also set:

          SDLNET_LIBRARY (same value as SDL_NET_LIBRARIES)
          SDLNET_INCLUDE_DIR (same value as SDL_NET_INCLUDE_DIRS)
          SDLNET_FOUND (same value as SDL_NET_FOUND)

       $SDLDIR is an environment variable that would correspond to the

       Created by Eric  Wing.   This  was  influenced  by  the  FindSDL.cmake  module,  but  with
       modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc).

   FindSDL
       Locate SDL library

       This module defines

          SDL_LIBRARY, the name of the library to link against
          SDL_FOUND, if false, do not try to link to SDL
          SDL_INCLUDE_DIR, where to find SDL.h
          SDL_VERSION_STRING, human-readable string containing the version of SDL

       This module responds to the flag:

          SDL_BUILDING_LIBRARY
            If this is defined, then no SDL_main will be linked in because
            only applications need main().
            Otherwise, it is assumed you are building an application and this
            module will attempt to locate and set the proper link flags
            as part of the returned SDL_LIBRARY variable.

       Don't  forget to include SDLmain.h and SDLmain.m your project for the OS X framework based
       version.  (Other versions link to -lSDLmain which this module will try  to  find  on  your
       behalf.)  Also  for  OS X, this module will automatically add the -framework Cocoa on your
       behalf.

       Additional Note: If you see  an  empty  SDL_LIBRARY_TEMP  in  your  configuration  and  no
       SDL_LIBRARY,   it  means  CMake  did  not  find  your  SDL  library  (SDL.dll,  libsdl.so,
       SDL.framework, etc).  Set SDL_LIBRARY_TEMP to point to your  SDL  library,  and  configure
       again.   Similarly,  if  you  see  an  empty SDLMAIN_LIBRARY, you should set this value as
       appropriate.  These values are used to generate the final SDL_LIBRARY variable,  but  when
       these values are unset, SDL_LIBRARY does not get created.

       $SDLDIR is an environment variable that would correspond to the

       Modified   by  Eric  Wing.   Added  code  to  assist  with  automated  building  by  using
       environmental variables and providing a more controlled/consistent search behavior.  Added
       new  modifications  to recognize OS X frameworks and additional Unix paths (FreeBSD, etc).
       Also corrected the header search path to follow "proper" SDL guidelines.  Added  a  search
       for SDLmain which is needed by some platforms.  Added a search for threads which is needed
       by some platforms.  Added needed compile switches for MinGW.

       On OSX, this will prefer the Framework version (if found) over others.  People  will  have
       to  manually  change the cache values of SDL_LIBRARY to override this selection or set the
       CMake environment CMAKE_INCLUDE_PATH to modify the search paths.

       Note that the header path has changed from SDL/SDL.h to just SDL.h This needed  to  change
       because  "proper"  SDL  convention is #include "SDL.h", not <SDL/SDL.h>.  This is done for
       portability reasons because not all systems place things in SDL/ (see FreeBSD).

   FindSDL_sound
       Locates the SDL_sound library

       This module depends on SDL being found and must be called AFTER FindSDL.cmake is called.

       This module defines

          SDL_SOUND_INCLUDE_DIR, where to find SDL_sound.h
          SDL_SOUND_FOUND, if false, do not try to link to SDL_sound
          SDL_SOUND_LIBRARIES, this contains the list of libraries that you need
            to link against. This is a read-only variable and is marked INTERNAL.
          SDL_SOUND_EXTRAS, this is an optional variable for you to add your own
            flags to SDL_SOUND_LIBRARIES. This is prepended to SDL_SOUND_LIBRARIES.
            This is available mostly for cases this module failed to anticipate for
            and you must add additional flags. This is marked as ADVANCED.
          SDL_SOUND_VERSION_STRING, human-readable string containing the
            version of SDL_sound

       This module also defines (but you shouldn't need to use directly)

          SDL_SOUND_LIBRARY, the name of just the SDL_sound library you would link
          against. Use SDL_SOUND_LIBRARIES for you link instructions and not this one.

       And might define the following as needed

          MIKMOD_LIBRARY
          MODPLUG_LIBRARY
          OGG_LIBRARY
          VORBIS_LIBRARY
          SMPEG_LIBRARY
          FLAC_LIBRARY
          SPEEX_LIBRARY

       Typically,  you  should  not  use  these  variables   directly,   and   you   should   use
       SDL_SOUND_LIBRARIES  which  contains  SDL_SOUND_LIBRARY  and the other audio libraries (if
       needed) to successfully compile on your system.

       Created by Eric Wing.  This module is a bit  more  complicated  than  the  other  FindSDL*
       family  modules.   The  reason  is  that  SDL_sound  can be compiled in a large variety of
       different ways which are independent of platform.  SDL_sound may dynamically link  against
       other  3rd  party  libraries  to  get additional codec support, such as Ogg Vorbis, SMPEG,
       ModPlug, MikMod, FLAC, Speex, and potentially others.  Under some  circumstances  which  I
       don't  fully  understand,  there  seems  to  be  a requirement that dependent libraries of
       libraries you use must also be explicitly linked against in order to successfully compile.
       SDL_sound  does  not  currently  have any system in place to know how it was compiled.  So
       this CMake module does the hard work in trying to discover which 3rd party  libraries  are
       required  for building (if any).  This module uses a brute force approach to create a test
       program that uses SDL_sound, and then tries to build it.  If the build  fails,  it  parses
       the error output for known symbol names to figure out which libraries are needed.

       Responds  to  the $SDLDIR and $SDLSOUNDDIR environmental variable that would correspond to
       the ./configure --prefix=$SDLDIR used in building SDL.

       On OSX, this will prefer the Framework version (if found) over others.  People  will  have
       to  manually  change  the cache values of SDL_LIBRARY to override this selectionor set the
       CMake environment CMAKE_INCLUDE_PATH to modify the search paths.

   FindSDL_ttf
       Locate SDL_ttf library

       This module defines:

          SDL_TTF_LIBRARIES, the name of the library to link against
          SDL_TTF_INCLUDE_DIRS, where to find the headers
          SDL_TTF_FOUND, if false, do not try to link against
          SDL_TTF_VERSION_STRING - human-readable string containing the version of SDL_ttf

       For backward compatiblity the following variables are also set:

          SDLTTF_LIBRARY (same value as SDL_TTF_LIBRARIES)
          SDLTTF_INCLUDE_DIR (same value as SDL_TTF_INCLUDE_DIRS)
          SDLTTF_FOUND (same value as SDL_TTF_FOUND)

       $SDLDIR is an environment variable that would correspond to the

       Created by Eric  Wing.   This  was  influenced  by  the  FindSDL.cmake  module,  but  with
       modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc).

   FindSelfPackers
       Find upx

       This module looks for some executable packers (i.e.  software that compress executables or
       shared libs into on-the-fly self-extracting executables or shared libs.  Examples:

          UPX: http://wildsau.idv.uni-linz.ac.at/mfx/upx.html

   FindSquish
       -- Typical Use

       This module can be used to find Squish.  Currently Squish versions 3 and 4 are supported.

          SQUISH_FOUND                    If false, don't try to use Squish
          SQUISH_VERSION                  The full version of Squish found
          SQUISH_VERSION_MAJOR            The major version of Squish found
          SQUISH_VERSION_MINOR            The minor version of Squish found
          SQUISH_VERSION_PATCH            The patch version of Squish found

          SQUISH_INSTALL_DIR              The Squish installation directory
                                          (containing bin, lib, etc)
          SQUISH_SERVER_EXECUTABLE        The squishserver executable
          SQUISH_CLIENT_EXECUTABLE        The squishrunner executable

          SQUISH_INSTALL_DIR_FOUND        Was the install directory found?
          SQUISH_SERVER_EXECUTABLE_FOUND  Was the server executable found?
          SQUISH_CLIENT_EXECUTABLE_FOUND  Was the client executable found?

       It provides the function squish_v4_add_test() for adding a  squish  test  to  cmake  using
       Squish 4.x:

          squish_v4_add_test(cmakeTestName
            AUT targetName SUITE suiteName TEST squishTestName
            [SETTINGSGROUP group] [PRE_COMMAND command] [POST_COMMAND command] )

       The arguments have the following meaning:

       cmakeTestName
              this will be used as the first argument for add_test()

       AUT targetName
              the  name  of the cmake target which will be used as AUT, i.e. the executable which
              will be tested.

       SUITE suiteName
              this is either the full path to the squish suite, or just the last directory of the
              suite,   i.e.  the  suite  name.  In  this  case  the  CMakeLists.txt  which  calls
              squish_add_test() must be located in the parent directory of the suite directory.

       TEST squishTestName
              the name of the squish test, i.e. the name of the subdirectory of the  test  inside
              the suite directory.

       SETTINGSGROUP group
              if specified, the given settings group will be used for executing the test.  If not
              specified, the groupname will be "CTest_<username>"

       PRE_COMMAND command
              if specified, the given command will be executed before starting the squish test.

       POST_COMMAND command
              same as PRE_COMMAND, but after the squish test has been executed.

          enable_testing()
          find_package(Squish 4.0)
          if (SQUISH_FOUND)
             squish_v4_add_test(myTestName
               AUT myApp
               SUITE ${CMAKE_SOURCE_DIR}/tests/mySuite
               TEST someSquishTest
               SETTINGSGROUP myGroup
               )
          endif ()

       For users of Squish version 3.x the macro squish_v3_add_test() is provided:

          squish_v3_add_test(testName applicationUnderTest testCase envVars testWrapper)
          Use this macro to add a test using Squish 3.x.

          enable_testing()
          find_package(Squish)
          if (SQUISH_FOUND)
            squish_v3_add_test(myTestName myApplication testCase envVars testWrapper)
          endif ()

       macro SQUISH_ADD_TEST(testName applicationUnderTest testCase envVars testWrapper)

          This is deprecated. Use SQUISH_V3_ADD_TEST() if you are using Squish 3.x instead.

   FindSubversion
       Extract information from a subversion working copy

       The module defines the following variables:

          Subversion_SVN_EXECUTABLE - path to svn command line client
          Subversion_VERSION_SVN - version of svn command line client
          Subversion_FOUND - true if the command line client was found
          SUBVERSION_FOUND - same as Subversion_FOUND, set for compatiblity reasons

       The minimum required version of Subversion can be specified  using  the  standard  syntax,
       e.g.  find_package(Subversion 1.4)

       If the command line client executable is found two macros are defined:

          Subversion_WC_INFO(<dir> <var-prefix>)
          Subversion_WC_LOG(<dir> <var-prefix>)

       Subversion_WC_INFO  extracts information of a subversion working copy at a given location.
       This macro defines the following variables:

          <var-prefix>_WC_URL - url of the repository (at <dir>)
          <var-prefix>_WC_ROOT - root url of the repository
          <var-prefix>_WC_REVISION - current revision
          <var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
          <var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
          <var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
          <var-prefix>_WC_INFO - output of command `svn info <dir>'

       Subversion_WC_LOG retrieves the log message of the base revision of a  subversion  working
       copy at a given location.  This macro defines the variable:

          <var-prefix>_LAST_CHANGED_LOG - last log of base revision

       Example usage:

          find_package(Subversion)
          if(SUBVERSION_FOUND)
            Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
            message("Current revision is ${Project_WC_REVISION}")
            Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
            message("Last changed log is ${Project_LAST_CHANGED_LOG}")
          endif()

   FindSWIG
       Find SWIG

       This module finds an installed SWIG.  It sets the following variables:

          SWIG_FOUND - set to true if SWIG is found
          SWIG_DIR - the directory where swig is installed
          SWIG_EXECUTABLE - the path to the swig executable
          SWIG_VERSION   - the version number of the swig executable

       The  minimum  required  version  of  SWIG can be specified using the standard syntax, e.g.
       find_package(SWIG 1.1)

       All information is collected from the SWIG_EXECUTABLE so the version to be  found  can  be
       changed from the command line by means of setting SWIG_EXECUTABLE

   FindTCL
       TK_INTERNAL_PATH was removed.

       This module finds if Tcl is installed and determines where the include files and libraries
       are.  It also determines what the name of the library is.  This code  sets  the  following
       variables:

          TCL_FOUND              = Tcl was found
          TK_FOUND               = Tk was found
          TCLTK_FOUND            = Tcl and Tk were found
          TCL_LIBRARY            = path to Tcl library (tcl tcl80)
          TCL_INCLUDE_PATH       = path to where tcl.h can be found
          TCL_TCLSH              = path to tclsh binary (tcl tcl80)
          TK_LIBRARY             = path to Tk library (tk tk80 etc)
          TK_INCLUDE_PATH        = path to where tk.h can be found
          TK_WISH                = full path to the wish executable

       In  an  effort  to  remove  some  clutter  and clear up some issues for people who are not
       necessarily Tcl/Tk gurus/developpers, some  variables  were  moved  or  removed.   Changes
       compared to CMake 2.4 are:

          => they were only useful for people writing Tcl/Tk extensions.
          => these libs are not packaged by default with Tcl/Tk distributions.
             Even when Tcl/Tk is built from source, several flavors of debug libs
             are created and there is no real reason to pick a single one
             specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx).
             Let's leave that choice to the user by allowing him to assign
             TCL_LIBRARY to any Tcl library, debug or not.
          => this ended up being only a Win32 variable, and there is a lot of
             confusion regarding the location of this file in an installed Tcl/Tk
             tree anyway (see 8.5 for example). If you need the internal path at
             this point it is safer you ask directly where the *source* tree is
             and dig from there.

   FindTclsh
       Find tclsh

       This module finds if TCL is installed and determines where the include files and libraries
       are.  It also determines what the name of the library is.  This code  sets  the  following
       variables:

          TCLSH_FOUND = TRUE if tclsh has been found
          TCL_TCLSH = the path to the tclsh executable

       In  cygwin,  look  for the cygwin version first.  Don't look for it later to avoid finding
       the cygwin version on a Win32 build.

   FindTclStub
       TCL_STUB_LIBRARY_DEBUG and TK_STUB_LIBRARY_DEBUG were removed.

       This module finds Tcl stub libraries.  It first finds Tcl include files and  libraries  by
       calling FindTCL.cmake.  How to Use the Tcl Stubs Library:

          http://tcl.activestate.com/doc/howto/stubs.html

       Using Stub Libraries:

          http://safari.oreilly.com/0130385603/ch48lev1sec3

       This code sets the following variables:

          TCL_STUB_LIBRARY       = path to Tcl stub library
          TK_STUB_LIBRARY        = path to Tk stub library
          TTK_STUB_LIBRARY       = path to ttk stub library

       In  an  effort  to  remove  some  clutter  and clear up some issues for people who are not
       necessarily Tcl/Tk gurus/developpers, some  variables  were  moved  or  removed.   Changes
       compared to CMake 2.4 are:

          => these libs are not packaged by default with Tcl/Tk distributions.
             Even when Tcl/Tk is built from source, several flavors of debug libs
             are created and there is no real reason to pick a single one
             specifically (say, amongst tclstub84g, tclstub84gs, or tclstub84sgx).
             Let's leave that choice to the user by allowing him to assign
             TCL_STUB_LIBRARY to any Tcl library, debug or not.

   FindThreads
       This module determines the thread library of the system.

       The following variables are set

          CMAKE_THREAD_LIBS_INIT     - the thread library
          CMAKE_USE_SPROC_INIT       - are we using sproc?
          CMAKE_USE_WIN32_THREADS_INIT - using WIN32 threads?
          CMAKE_USE_PTHREADS_INIT    - are we using pthreads
          CMAKE_HP_PTHREADS_INIT     - are we using hp pthreads

       The following import target is created

          Threads::Threads

       For systems with multiple thread libraries, caller can set

          CMAKE_THREAD_PREFER_PTHREAD

       If the use of the -pthread compiler and linker flag is prefered then the caller can set

          THREADS_PREFER_PTHREAD_FLAG

       Please  note that the compiler flag can only be used with the imported target. Use of both
       the imported target as well as this switch is highly recommended for new code.

   FindTIFF
       Find the TIFF library (libtiff).

   Imported targets
       This module defines the following IMPORTED targets:

       TIFF::TIFF
              The TIFF library, if found.

   Result variables
       This module will set the following variables in your project:

       TIFF_FOUND
              true if the TIFF headers and libraries were found

       TIFF_INCLUDE_DIR
              the directory containing the TIFF headers

       TIFF_INCLUDE_DIRS
              the directory containing the TIFF headers

       TIFF_LIBRARIES
              TIFF libraries to be linked

   Cache variables
       The following cache variables may also be set:

       TIFF_INCLUDE_DIR
              the directory containing the TIFF headers

       TIFF_LIBRARY
              the path to the TIFF library

   FindUnixCommands
       Find Unix commands, including the ones from Cygwin

       This module looks for the Unix commands bash, cp, gzip, mv, rm, and  tar  and  stores  the
       result in the variables BASH, CP, GZIP, MV, RM, and TAR.

   FindVTK
       This module no longer exists.

       This  module  existed  in  versions  of CMake prior to 3.1, but became only a thin wrapper
       around  find_package(VTK  NO_MODULE)  to  provide   compatibility   for   projects   using
       long-outdated   conventions.    Now  find_package(VTK)  will  search  for  VTKConfig.cmake
       directly.

   FindWget
       Find wget

       This module looks for wget.  This module defines the following values:

          WGET_EXECUTABLE: the full path to the wget tool.
          WGET_FOUND: True if wget has been found.

   FindWish
       Find wish installation

       This module finds if TCL is installed and determines where the include files and libraries
       are.   It  also  determines what the name of the library is.  This code sets the following
       variables:

          TK_WISH = the path to the wish executable

       if UNIX is defined, then it will look for the cygwin version first

   FindwxWidgets
       Find a wxWidgets (a.k.a., wxWindows) installation.

       This module finds if wxWidgets is installed and selects a default  configuration  to  use.
       wxWidgets  is  a  modular  library.  To specify the modules that you will use, you need to
       name them as components to the package:

       find_package(wxWidgets COMPONENTS core base ...)

       There are two search branches: a windows  style  and  a  unix  style.   For  windows,  the
       following  variables  are  searched  for  and set to defaults in case of multiple choices.
       Change them if the defaults are not desired (i.e., these are the only variables you should
       change to select a configuration):

          wxWidgets_ROOT_DIR      - Base wxWidgets directory
                                    (e.g., C:/wxWidgets-2.6.3).
          wxWidgets_LIB_DIR       - Path to wxWidgets libraries
                                    (e.g., C:/wxWidgets-2.6.3/lib/vc_lib).
          wxWidgets_CONFIGURATION - Configuration to use
                                    (e.g., msw, mswd, mswu, mswunivud, etc.)
          wxWidgets_EXCLUDE_COMMON_LIBRARIES
                                  - Set to TRUE to exclude linking of
                                    commonly required libs (e.g., png tiff
                                    jpeg zlib regex expat).

       For  unix  style  it  uses  the  wx-config utility.  You can select between debug/release,
       unicode/ansi,  universal/non-universal,  and  static/shared  in  the  QtDialog  or  ccmake
       interfaces by turning ON/OFF the following variables:

          wxWidgets_USE_DEBUG
          wxWidgets_USE_UNICODE
          wxWidgets_USE_UNIVERSAL
          wxWidgets_USE_STATIC

       There  is  also  a wxWidgets_CONFIG_OPTIONS variable for all other options that need to be
       passed to the wx-config utility.  For example, to  use  the  base  toolkit  found  in  the
       /usr/local path, set the variable (before calling the FIND_PACKAGE command) as such:

          set(wxWidgets_CONFIG_OPTIONS --toolkit=base --prefix=/usr)

       The following are set after the configuration is done for both windows and unix style:

          wxWidgets_FOUND            - Set to TRUE if wxWidgets was found.
          wxWidgets_INCLUDE_DIRS     - Include directories for WIN32
                                       i.e., where to find "wx/wx.h" and
                                       "wx/setup.h"; possibly empty for unices.
          wxWidgets_LIBRARIES        - Path to the wxWidgets libraries.
          wxWidgets_LIBRARY_DIRS     - compile time link dirs, useful for
                                       rpath on UNIX. Typically an empty string
                                       in WIN32 environment.
          wxWidgets_DEFINITIONS      - Contains defines required to compile/link
                                       against WX, e.g. WXUSINGDLL
          wxWidgets_DEFINITIONS_DEBUG- Contains defines required to compile/link
                                       against WX debug builds, e.g. __WXDEBUG__
          wxWidgets_CXX_FLAGS        - Include dirs and compiler flags for
                                       unices, empty on WIN32. Essentially
                                       "`wx-config --cxxflags`".
          wxWidgets_USE_FILE         - Convenience include file.

       Sample usage:

          # Note that for MinGW users the order of libs is important!
          find_package(wxWidgets COMPONENTS net gl core base)
          if(wxWidgets_FOUND)
            include(${wxWidgets_USE_FILE})
            # and for each of your dependent executable/library targets:
            target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})
          endif()

       If wxWidgets is required (i.e., not an optional part):

          find_package(wxWidgets REQUIRED net gl core base)
          include(${wxWidgets_USE_FILE})
          # and for each of your dependent executable/library targets:
          target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})

   FindwxWindows
       Find wxWindows (wxWidgets) installation

       This  module  finds  if  wxWindows/wxWidgets is installed and determines where the include
       files and libraries are.  It also determines what the name of the library is.  Please note
       this file is DEPRECATED and replaced by FindwxWidgets.cmake.  This code sets the following
       variables:

          WXWINDOWS_FOUND     = system has WxWindows
          WXWINDOWS_LIBRARIES = path to the wxWindows libraries
                                on Unix/Linux with additional
                                linker flags from
                                "wx-config --libs"
          CMAKE_WXWINDOWS_CXX_FLAGS  = Compiler flags for wxWindows,
                                       essentially "`wx-config --cxxflags`"
                                       on Linux
          WXWINDOWS_INCLUDE_DIR      = where to find "wx/wx.h" and "wx/setup.h"
          WXWINDOWS_LINK_DIRECTORIES = link directories, useful for rpath on
                                        Unix
          WXWINDOWS_DEFINITIONS      = extra defines

       OPTIONS If you need OpenGL support please

          set(WXWINDOWS_USE_GL 1)

       in your CMakeLists.txt before you include this file.

          HAVE_ISYSTEM      - true required to replace -I by -isystem on g++

       For  convenience  include  Use_wxWindows.cmake  in  your  project's  CMakeLists.txt  using
       include(${CMAKE_CURRENT_LIST_DIR}/Use_wxWindows.cmake).

       USAGE

          set(WXWINDOWS_USE_GL 1)
          find_package(wxWindows)

       names:

          FortranCInterface_HEADER(<file>
                                   [MACRO_NAMESPACE <macro-ns>]
                                   [SYMBOL_NAMESPACE <ns>]
                                   [SYMBOLS [<module>:]<function> ...])

       It generates in <file> definitions of the following macros:

          #define FortranCInterface_GLOBAL (name,NAME) ...
          #define FortranCInterface_GLOBAL_(name,NAME) ...
          #define FortranCInterface_MODULE (mod,name, MOD,NAME) ...
          #define FortranCInterface_MODULE_(mod,name, MOD,NAME) ...

       These macros mangle four categories of Fortran symbols, respectively:

          - Global symbols without '_': call mysub()
          - Global symbols with '_'   : call my_sub()
          - Module symbols without '_': use mymod; call mysub()
          - Module symbols with '_'   : use mymod; call my_sub()

       If mangling for a category is not known, its macro is left undefined.  All macros  require
       raw  names  in  both  lower  case and upper case.  The MACRO_NAMESPACE option replaces the
       default "FortranCInterface" prefix with a given namespace "<macro-ns>".

       The SYMBOLS option lists symbols to mangle automatically with C preprocessor definitions:

          <function>          ==> #define <ns><function> ...
          <module>:<function> ==> #define <ns><module>_<function> ...

       If the mangling for some symbol is not known then no preprocessor definition  is  created,
       and  a  warning  is  displayed.   The  SYMBOL_NAMESPACE  option  prefixes all preprocessor
       definitions generated by the SYMBOLS option with a given namespace "<ns>".

       Example usage:

          include(FortranCInterface)
          FortranCInterface_HEADER(FC.h MACRO_NAMESPACE "FC_")

       This creates a "FC.h" header  that  defines  mangling  macros  FC_GLOBAL(),  FC_GLOBAL_(),
       FC_MODULE(), and FC_MODULE_().

       Example usage:

          include(FortranCInterface)
          FortranCInterface_HEADER(FCMangle.h
                                   MACRO_NAMESPACE "FC_"
                                   SYMBOL_NAMESPACE "FC_"
                                   SYMBOLS mysub mymod:my_sub)

       This  creates  a  "FCMangle.h"  header that defines the same FC_*() mangling macros as the
       previous example plus preprocessor symbols FC_mysub and FC_mymod_my_sub.

       Another function is provided to verify that the Fortran and C/C++ compilers work together:

          FortranCInterface_VERIFY([CXX] [QUIET])

       It tests whether a simple test executable using Fortran and C (and C++ when the CXX option
       is  given)  compiles  and  links  successfully.   The  result is stored in the cache entry
       FortranCInterface_VERIFIED_C (or FortranCInterface_VERIFIED_CXX if  CXX  is  given)  as  a
       boolean.   If  the  check  fails  and  QUIET  is  not given the function terminates with a
       FATAL_ERROR message describing the problem.  The purpose of this check is to stop a  build
       early  for  incompatible  compiler  combinations.   The  test  is  built  in  the  Release
       configuration.

       FortranCInterface is aware of possible  GLOBAL  and  MODULE  manglings  for  many  Fortran
       compilers,  but  it also provides an interface to specify new possible manglings.  Set the
       variables

          FortranCInterface_GLOBAL_SYMBOLS
          FortranCInterface_MODULE_SYMBOLS

       before including FortranCInterface to specify manglings of the symbols "MySub",  "My_Sub",
       "MyModule:MySub", and "My_Module:My_Sub".  For example, the code:

          set(FortranCInterface_GLOBAL_SYMBOLS mysub_ my_sub__ MYSUB_)
            #                                  ^^^^^  ^^^^^^   ^^^^^
          set(FortranCInterface_MODULE_SYMBOLS
              __mymodule_MOD_mysub __my_module_MOD_my_sub)
            #   ^^^^^^^^     ^^^^^   ^^^^^^^^^     ^^^^^^
          include(FortranCInterface)

       tells  FortranCInterface  to  try given GLOBAL and MODULE manglings.  (The carets point at
       raw symbol names for clarity in this example but are not needed.)

   GenerateExportHeader
       Function for generation of export macros for libraries

       This module provides the function GENERATE_EXPORT_HEADER().

       The  GENERATE_EXPORT_HEADER  function  can  be  used  to  generate  a  file  suitable  for
       preprocessor inclusion which contains EXPORT macros to be used in library classes:

          GENERATE_EXPORT_HEADER( LIBRARY_TARGET
                    [BASE_NAME <base_name>]
                    [EXPORT_MACRO_NAME <export_macro_name>]
                    [EXPORT_FILE_NAME <export_file_name>]
                    [DEPRECATED_MACRO_NAME <deprecated_macro_name>]
                    [NO_EXPORT_MACRO_NAME <no_export_macro_name>]
                    [STATIC_DEFINE <static_define>]
                    [NO_DEPRECATED_MACRO_NAME <no_deprecated_macro_name>]
                    [DEFINE_NO_DEPRECATED]
                    [PREFIX_NAME <prefix_name>]
          )

       The  target  properties CXX_VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN can be used to
       add the appropriate compile flags for targets.  See  the  documentation  of  those  target
       properties,    and    the    convenience    variables    CMAKE_CXX_VISIBILITY_PRESET   and
       CMAKE_VISIBILITY_INLINES_HIDDEN.

       By default GENERATE_EXPORT_HEADER() generates macro names in a file name determined by the
       name  of the library.  This means that in the simplest case, users of GenerateExportHeader
       will be equivalent to:

          set(CMAKE_CXX_VISIBILITY_PRESET hidden)
          set(CMAKE_VISIBILITY_INLINES_HIDDEN 1)
          add_library(somelib someclass.cpp)
          generate_export_header(somelib)
          install(TARGETS somelib DESTINATION ${LIBRARY_INSTALL_DIR})
          install(FILES
           someclass.h
           ${PROJECT_BINARY_DIR}/somelib_export.h DESTINATION ${INCLUDE_INSTALL_DIR}
          )

       And in the ABI header files:

          #include "somelib_export.h"
          class SOMELIB_EXPORT SomeClass {
            ...
          };

       The CMake  fragment  will  generate  a  file  in  the  ${CMAKE_CURRENT_BINARY_DIR}  called
       somelib_export.h     containing     the    macros    SOMELIB_EXPORT,    SOMELIB_NO_EXPORT,
       SOMELIB_DEPRECATED,  SOMELIB_DEPRECATED_EXPORT  and   SOMELIB_DEPRECATED_NO_EXPORT.    The
       resulting file should be installed with other headers in the library.

       The  BASE_NAME  argument  can be used to override the file name and the names used for the
       macros:

          add_library(somelib someclass.cpp)
          generate_export_header(somelib
            BASE_NAME other_name
          )

       Generates a file  called  other_name_export.h  containing  the  macros  OTHER_NAME_EXPORT,
       OTHER_NAME_NO_EXPORT and OTHER_NAME_DEPRECATED etc.

       The  BASE_NAME  may  be  overridden  by  specifiying  other  options in the function.  For
       example:

          add_library(somelib someclass.cpp)
          generate_export_header(somelib
            EXPORT_MACRO_NAME OTHER_NAME_EXPORT
          )

       creates the macro OTHER_NAME_EXPORT instead of SOMELIB_EXPORT, but other  macros  and  the
       generated file name is as default:

          add_library(somelib someclass.cpp)
          generate_export_header(somelib
            DEPRECATED_MACRO_NAME KDE_DEPRECATED
          )

       creates the macro KDE_DEPRECATED instead of SOMELIB_DEPRECATED.

       If LIBRARY_TARGET is a static library, macros are defined without values.

       If  the same sources are used to create both a shared and a static library, the uppercased
       symbol ${BASE_NAME}_STATIC_DEFINE should be used when building the static library:

          add_library(shared_variant SHARED ${lib_SRCS})
          add_library(static_variant ${lib_SRCS})
          generate_export_header(shared_variant BASE_NAME libshared_and_static)
          set_target_properties(static_variant PROPERTIES
            COMPILE_FLAGS -DLIBSHARED_AND_STATIC_STATIC_DEFINE)

       This will cause the export macros to expand to nothing when building the static library.

       If DEFINE_NO_DEPRECATED is specified, then  a  macro  ${BASE_NAME}_NO_DEPRECATED  will  be
       defined This macro can be used to remove deprecated code from preprocessor output:

          option(EXCLUDE_DEPRECATED "Exclude deprecated parts of the library" FALSE)
          if (EXCLUDE_DEPRECATED)
            set(NO_BUILD_DEPRECATED DEFINE_NO_DEPRECATED)
          endif()
          generate_export_header(somelib ${NO_BUILD_DEPRECATED})

       And then in somelib:

          class SOMELIB_EXPORT SomeClass
          {
          public:
          #ifndef SOMELIB_NO_DEPRECATED
            SOMELIB_DEPRECATED void oldMethod();
          #endif
          };

          #ifndef SOMELIB_NO_DEPRECATED
          void SomeClass::oldMethod() {  }
          #endif

       If  PREFIX_NAME  is  specified,  the  argument  will  be used as a prefix to all generated
       macros.

       For example:

          generate_export_header(somelib PREFIX_NAME VTK_)

       Generates the macros VTK_SOMELIB_EXPORT etc.

          ADD_COMPILER_EXPORT_FLAGS( [<output_variable>] )

       The ADD_COMPILER_EXPORT_FLAGS function  adds  -fvisibility=hidden  to  CMAKE_CXX_FLAGS  if
       supported,  and  is  a  no-op  on  Windows  which  does  not need extra compiler flags for
       exporting support.  You may optionally pass a single argument to ADD_COMPILER_EXPORT_FLAGS
       that  will  be  populated with the CXX_FLAGS required to enable visibility support for the
       compiler/architecture in use.

       This  function  is  deprecated.   Set  the  target  properties  CXX_VISIBILITY_PRESET  and
       VISIBILITY_INLINES_HIDDEN instead.

   GetPrerequisites
       Functions to analyze and list executable file prerequisites.

       This module provides functions to list the .dll, .dylib or .so files that an executable or
       shared library file depends on.  (Its prerequisites.)

       It uses various tools to obtain the list of required shared library files:

          dumpbin (Windows)
          objdump (MinGW on Windows)
          ldd (Linux/Unix)
          otool (Mac OSX)

       The following functions are provided by this module:

          get_prerequisites
          list_prerequisites
          list_prerequisites_by_glob
          gp_append_unique
          is_file_executable
          gp_item_default_embedded_path
            (projects can override with gp_item_default_embedded_path_override)
          gp_resolve_item
            (projects can override with gp_resolve_item_override)
          gp_resolved_file_type
            (projects can override with gp_resolved_file_type_override)
          gp_file_type

       Requires CMake 2.6 or greater because it uses function, break, return and PARENT_SCOPE.

          GET_PREREQUISITES(<target> <prerequisites_var> <exclude_system> <recurse>
                            <exepath> <dirs> [<rpaths>])

       Get the list of shared library files required by <target>.  The list in the variable named
       <prerequisites_var>   should  be  empty  on  first  entry  to  this  function.   On  exit,
       <prerequisites_var> will contain the list of required shared library files.

       <target> is the full path to an executable file.  <prerequisites_var> is  the  name  of  a
       CMake variable to contain the results.  <exclude_system> must be 0 or 1 indicating whether
       to include or exclude "system" prerequisites.  If <recurse> is set to 1 all  prerequisites
       will be found recursively, if set to 0 only direct prerequisites are listed.  <exepath> is
       the path to the top level executable used for  @executable_path  replacment  on  the  Mac.
       <dirs>  is  a list of paths where libraries might be found: these paths are searched first
       when a target without any path info is given.  Then standard  system  locations  are  also
       searched: PATH, Framework locations, /usr/lib...

          LIST_PREREQUISITES(<target> [<recurse> [<exclude_system> [<verbose>]]])

       Print a message listing the prerequisites of <target>.

       <target> is the name of a shared library or executable target or the full path to a shared
       library or executable file.  If <recurse> is set to 1  all  prerequisites  will  be  found
       recursively, if set to 0 only direct prerequisites are listed.  <exclude_system> must be 0
       or 1 indicating whether to include or exclude "system" prerequisites.  With <verbose>  set
       to  0 only the full path names of the prerequisites are printed, set to 1 extra informatin
       will be displayed.

          LIST_PREREQUISITES_BY_GLOB(<glob_arg> <glob_exp>)

       Print the prerequisites of  shared  library  and  executable  files  matching  a  globbing
       pattern.   <glob_arg> is GLOB or GLOB_RECURSE and <glob_exp> is a globbing expression used
       with "file(GLOB" or "file(GLOB_RECURSE" to retrieve  a  list  of  matching  files.   If  a
       matching file is executable, its prerequisites are listed.

       Any additional (optional) arguments provided are passed along as the optional arguments to
       the list_prerequisites calls.

          GP_APPEND_UNIQUE(<list_var> <value>)

       Append <value> to the list variable <list_var> only if the value is  not  already  in  the
       list.

          IS_FILE_EXECUTABLE(<file> <result_var>)

       Return 1 in <result_var> if <file> is a binary executable, 0 otherwise.

          GP_ITEM_DEFAULT_EMBEDDED_PATH(<item> <default_embedded_path_var>)

       Return the path that others should refer to the item by when the item is embedded inside a
       bundle.

       Override    on    a    per-project    basis    by     providing     a     project-specific
       gp_item_default_embedded_path_override function.

          GP_RESOLVE_ITEM(<context> <item> <exepath> <dirs> <resolved_item_var>
                          [<rpaths>])

       Resolve an item into an existing full path file.

       Override  on  a per-project basis by providing a project-specific gp_resolve_item_override
       function.

          GP_RESOLVED_FILE_TYPE(<original_file> <file> <exepath> <dirs> <type_var>
                                [<rpaths>])

       Return the type of <file> with respect to  <original_file>.   String  describing  type  of
       prerequisite is returned in variable named <type_var>.

       Use  <exepath>  and  <dirs> if necessary to resolve non-absolute <file> values -- but only
       for non-embedded items.

       Possible types are:

          system
          local
          embedded
          other

       Override    on    a    per-project    basis    by     providing     a     project-specific
       gp_resolved_file_type_override function.

          GP_FILE_TYPE(<original_file> <file> <type_var>)

       Return  the  type  of  <file>  with respect to <original_file>.  String describing type of
       prerequisite is returned in variable named <type_var>.

       Possible types are:

          system
          local
          embedded
          other

   GNUInstallDirs
       Define GNU standard installation directories

       Provides install directory variables as defined by the GNU Coding Standards.

   Result Variables
       Inclusion of this module defines the following variables:

       CMAKE_INSTALL_<dir>
          Destination for files of a given type.  This value may be  passed  to  the  DESTINATION
          options of install() commands for the corresponding file type.

       CMAKE_INSTALL_FULL_<dir>
          The  absolute  path generated from the corresponding CMAKE_INSTALL_<dir> value.  If the
          value is not already an absolute path, an absolute path  is  constructed  typically  by
          prepending  the  value  of  the CMAKE_INSTALL_PREFIX variable.  However, there are some
          special cases as documented below.

       where <dir> is one of:

       BINDIR user executables (bin)

       SBINDIR
              system admin executables (sbin)

       LIBEXECDIR
              program executables (libexec)

       SYSCONFDIR
              read-only single-machine data (etc)

       SHAREDSTATEDIR
              modifiable architecture-independent data (com)

       LOCALSTATEDIR
              modifiable single-machine data (var)

       LIBDIR object code libraries (lib or lib64 or lib/<multiarch-tuple> on Debian)

       INCLUDEDIR
              C header files (include)

       OLDINCLUDEDIR
              C header files for non-gcc (/usr/include)

       DATAROOTDIR
              read-only architecture-independent data root (share)

       DATADIR
              read-only architecture-independent data (DATAROOTDIR)

       INFODIR
              info documentation (DATAROOTDIR/info)

       LOCALEDIR
              locale-dependent data (DATAROOTDIR/locale)

       MANDIR man documentation (DATAROOTDIR/man)

       DOCDIR documentation root (DATAROOTDIR/doc/PROJECT_NAME)

       If the includer does not define a value the above-shown default will be used and the value
       will appear in the cache for editing by the user.

   Special Cases
       The following values of CMAKE_INSTALL_PREFIX are special:

       /
          For <dir> other than the SYSCONFDIR and LOCALSTATEDIR, the value of CMAKE_INSTALL_<dir>
          is prefixed with usr/ if it is not user-specified as an absolute  path.   For  example,
          the  INCLUDEDIR  value include becomes usr/include.  This is required by the GNU Coding
          Standards, which state:
              When building the complete GNU system, the prefix will be empty and /usr will be  a
              symbolic link to /.

       /usr
          For  <dir>  equal  to  SYSCONFDIR  or  LOCALSTATEDIR,  the  CMAKE_INSTALL_FULL_<dir> is
          computed by prepending just /  to  the  value  of  CMAKE_INSTALL_<dir>  if  it  is  not
          user-specified  as  an  absolute  path.   For example, the SYSCONFDIR value etc becomes
          /etc.  This is required by the GNU Coding Standards.

       /opt/...
          For <dir>  equal  to  SYSCONFDIR  or  LOCALSTATEDIR,  the  CMAKE_INSTALL_FULL_<dir>  is
          computed  by  appending  the  prefix  to  the value of CMAKE_INSTALL_<dir> if it is not
          user-specified as an absolute path.  For example,  the  SYSCONFDIR  value  etc  becomes
          /etc/opt/....  This is defined by the Filesystem Hierarchy Standard.

   InstallRequiredSystemLibraries
       Include  this  module  to  search  for  compiler-provided system runtime libraries and add
       install rules for them.  Some optional variables may be set prior to including the  module
       to adjust behavior:

       CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS
              Specify additional runtime libraries that may not be detected.  After inclusion any
              detected libraries will be appended to this.

       CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_SKIP
              Set to TRUE to skip calling the install(PROGRAMS) command to allow the includer  to
              specify  its own install rule, using the value of CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS
              to get the list of libraries.

       CMAKE_INSTALL_DEBUG_LIBRARIES
              Set to TRUE to install the debug runtime libraries when available with MSVC tools.

       CMAKE_INSTALL_DEBUG_LIBRARIES_ONLY
              Set to TRUE to install only the debug runtime libraries with MSVC tools even if the
              release runtime libraries are also available.

       CMAKE_INSTALL_MFC_LIBRARIES
              Set to TRUE to install the MSVC MFC runtime libraries.

       CMAKE_INSTALL_OPENMP_LIBRARIES
              Set to TRUE to install the MSVC OpenMP runtime libraries

       CMAKE_INSTALL_SYSTEM_RUNTIME_DESTINATION
              Specify  the  install(PROGRAMS)  command DESTINATION option.  If not specified, the
              default is bin on Windows and lib elsewhere.

       CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_NO_WARNINGS
              Set to TRUE to disable warnings about required library files  that  do  not  exist.
              (For  example,  Visual  Studio Express editions may not provide the redistributable
              files.)

       CMAKE_INSTALL_SYSTEM_RUNTIME_COMPONENT
              Specify the install(PROGRAMS) command COMPONENT option.  If not specified, no  such
              option will be used.

   MacroAddFileDependencies
       MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...)

       Using  the  macro  MACRO_ADD_FILE_DEPENDENCIES() is discouraged.  There are usually better
       ways to specify the correct dependencies.

       MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...) is just a convenience wrapper  around
       the  OBJECT_DEPENDS  source  file  property.   You can just use set_property(SOURCE <file>
       APPEND PROPERTY OBJECT_DEPENDS depend_files) instead.

   ProcessorCount
       ProcessorCount(var)

       Determine the number of processors/cores and save value in ${var}

       Sets the variable named ${var} to the number of physical cores available on the machine if
       the   information  can  be  determined.   Otherwise  it  is  set  to  0.   Currently  this
       functionality is implemented for AIX, cygwin, FreeBSD, HPUX, IRIX, Linux, Mac OS  X,  QNX,
       Sun and Windows.

       This function is guaranteed to return a positive integer (>=1) if it succeeds.  It returns
       0 if there's a problem determining the processor count.

       Example use, in a ctest -S dashboard script:

          include(ProcessorCount)
          ProcessorCount(N)
          if(NOT N EQUAL 0)
            set(CTEST_BUILD_FLAGS -j${N})
            set(ctest_test_args ${ctest_test_args} PARALLEL_LEVEL ${N})
          endif()

       This function is intended to offer an approximation of the value of the number of  compute
       cores  available  on  the  current  machine, such that you may use that value for parallel
       building and parallel testing.  It is meant to help utilize as  much  of  the  machine  as
       seems  reasonable.   Of  course,  knowledge  of  what else might be running on the machine
       simultaneously should be used when deciding whether to request a machine's  full  capacity
       all for yourself.

   SelectLibraryConfigurations
       select_library_configurations( basename )

       This  macro  takes  a  library  base  name as an argument, and will choose good values for
       basename_LIBRARY, basename_LIBRARIES, basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE
       depending  on  what  has been found and set.  If only basename_LIBRARY_RELEASE is defined,
       basename_LIBRARY will be set to the release value, and basename_LIBRARY_DEBUG will be  set
       to  basename_LIBRARY_DEBUG-NOTFOUND.   If  only  basename_LIBRARY_DEBUG  is  defined, then
       basename_LIBRARY will take the debug value, and basename_LIBRARY_RELEASE will  be  set  to
       basename_LIBRARY_RELEASE-NOTFOUND.

       If    the    generator   supports   configuration   types,   then   basename_LIBRARY   and
       basename_LIBRARIES will be set with debug and optimized flags specifying the library to be
       used  for  the given configuration.  If no build type has been set or the generator in use
       does not support configuration types, then basename_LIBRARY  and  basename_LIBRARIES  will
       take only the release value, or the debug value if the release one is not set.

   SquishTestScript
       This  script  launches  a GUI test using Squish.  You should not call the script directly;
       instead,  you  should  access  it  via  the  SQUISH_ADD_TEST  macro  that  is  defined  in
       FindSquish.cmake.

       This  script  starts the Squish server, launches the test on the client, and finally stops
       the squish server.  If any of these steps fail (including if the tests do not pass) then a
       fatal error is raised.

   UseEcos
       This module defines variables and macros required to build eCos application.

       This file contains the following macros: ECOS_ADD_INCLUDE_DIRECTORIES()  -  add  the  eCos
       include  dirs  ECOS_ADD_EXECUTABLE(name source1 ...  sourceN ) - create an eCos executable
       ECOS_ADJUST_DIRECTORY(VAR source1 ...  sourceN ) - adjusts the path of  the  source  files
       and puts the result into VAR

       Macros  for  selecting  the  toolchain:  ECOS_USE_ARM_ELF_TOOLS()  -  enable  the  ARM ELF

       It   contains   the   following    variables:    ECOS_DEFINITIONS    ECOSCONFIG_EXECUTABLE
       ECOS_CONFIG_FILE  -  defaults to ecos.ecc, if your eCos configuration file has a different
       name, adjust this variable for internal use only:

          ECOS_ADD_TARGET_LIB

   UseJavaClassFilelist
       This script create a list of compiled Java class files to be added to a  jar  file.   This
       avoids including cmake files which get created in the binary directory.

   UseJava
       Use Module for Java

       This file provides functions for Java.  It is assumed that FindJava.cmake has already been
       loaded.  See FindJava.cmake for information on how to load Java into your CMake project.

          add_jar(target_name
                  [SOURCES] source1 [source2 ...] [resource1 ...]
                  [INCLUDE_JARS jar1 [jar2 ...]]
                  [ENTRY_POINT entry]
                  [VERSION version]
                  [OUTPUT_NAME name]
                  [OUTPUT_DIR dir]
                  )

       This command creates a <target_name>.jar.  It compiles the given source files (source) and
       adds  the given resource files (resource) to the jar file.  Source files can be java files
       or listing files (prefixed by '@').  If only resource files are given then just a jar file
       is  created.   The list of include jars are added to the classpath when compiling the java
       sources and also to the dependencies of  the  target.   INCLUDE_JARS  also  accepts  other
       target names created by add_jar.  For backwards compatibility, jar files listed as sources
       are ignored (as they have been since the first version of this module).

       The   default   OUTPUT_DIR   can   also   be   changed    by    setting    the    variable
       CMAKE_JAVA_TARGET_OUTPUT_DIR.

       Additional instructions:

          To add compile flags to the target you can set these flags with
          the following variable:

          set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)

          To add a path or a jar file to the class path you can do this
          with the CMAKE_JAVA_INCLUDE_PATH variable.

          set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)

          To use a different output name for the target you can set it with:

          add_jar(foobar foobar.java OUTPUT_NAME shibboleet.jar)

          To use a different output directory than CMAKE_CURRENT_BINARY_DIR
          you can set it with:

          add_jar(foobar foobar.java OUTPUT_DIR ${PROJECT_BINARY_DIR}/bin)

          To define an entry point in your jar you can set it with the ENTRY_POINT
          named argument:

          add_jar(example ENTRY_POINT com/examples/MyProject/Main)

          To define a custom manifest for the jar, you can set it with the manifest
          named argument:

          add_jar(example MANIFEST /path/to/manifest)

          To add a VERSION to the target output name you can set it using
          the VERSION named argument to add_jar. This will create a jar file with the
          name shibboleet-1.0.0.jar and will create a symlink shibboleet.jar
          pointing to the jar with the version information.

          add_jar(shibboleet shibbotleet.java VERSION 1.2.0)

          If the target is a JNI library, utilize the following commands to
          create a JNI symbolic link:

          set(CMAKE_JNI_TARGET TRUE)
          add_jar(shibboleet shibbotleet.java VERSION 1.2.0)
          install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet)
          install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})

          If a single target needs to produce more than one jar from its
          java source code, to prevent the accumulation of duplicate class
          files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior
          to calling the add_jar() function:

          set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo)
          add_jar(foo foo.java)

          set(CMAKE_JAR_CLASSES_PREFIX com/redhat/bar)
          add_jar(bar bar.java)

       Target Properties:

          The add_jar() functions sets some target properties. You can get these
          properties with the
             get_property(TARGET <target_name> PROPERTY <propery_name>)
          command.

          INSTALL_FILES      The files which should be installed. This is used by
                             install_jar().
          JNI_SYMLINK        The JNI symlink which should be installed.
                             This is used by install_jni_symlink().
          JAR_FILE           The location of the jar file so that you can include
                             it.
          CLASSDIR           The directory where the class files can be found. For
                             example to use them with javah.

          find_jar(<VAR>
                   name | NAMES name1 [name2 ...]
                   [PATHS path1 [path2 ... ENV var]]
                   [VERSIONS version1 [version2]]
                   [DOC "cache documentation string"]
                   )

       This  command  is used to find a full path to the named jar.  A cache entry named by <VAR>
       is created to stor the result of this command.  If the full path to a  jar  is  found  the
       result  is  stored in the variable and the search will not repeated unless the variable is
       cleared.  If nothing is found, the result will be <VAR>-NOTFOUND, and the search  will  be
       attempted  again  next  time  find_jar is invoked with the same variable.  The name of the
       full path to a file that is searched for is specified by  the  names  listed  after  NAMES
       argument.   Additional search locations can be specified after the PATHS argument.  If you
       require special a version of a jar file you can specify it  with  the  VERSIONS  argument.
       The argument after DOC will be used for the documentation string in the cache.

          install_jar(target_name destination)
          install_jar(target_name DESTINATION destination [COMPONENT component])

       This command installs the TARGET_NAME files to the given DESTINATION.  It should be called
       in the same scope as add_jar() or it will fail.

          install_jni_symlink(target_name destination)
          install_jni_symlink(target_name DESTINATION destination [COMPONENT component])

       This command installs the TARGET_NAME JNI symlinks to the given DESTINATION.  It should be
       called in the same scope as add_jar() or it will fail.

          create_javadoc(<VAR>
                         PACKAGES pkg1 [pkg2 ...]
                         [SOURCEPATH <sourcepath>]
                         [CLASSPATH <classpath>]
                         [INSTALLPATH <install path>]
                         [DOCTITLE "the documentation title"]
                         [WINDOWTITLE "the title of the document"]
                         [AUTHOR TRUE|FALSE]
                         [USE TRUE|FALSE]
                         [VERSION TRUE|FALSE]
                         )

       Create  java  documentation  based on files or packages.  For more details please read the
       javadoc manpage.

       There are two main signatures for create_javadoc.  The first signature works with  package
       names on a path with source files:

          Example:
          create_javadoc(my_example_doc
            PACKAGES com.exmaple.foo com.example.bar
            SOURCEPATH "${CMAKE_CURRENT_SOURCE_DIR}"
            CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
            WINDOWTITLE "My example"
            DOCTITLE "<h1>My example</h1>"
            AUTHOR TRUE
            USE TRUE
            VERSION TRUE
          )

       The second signature for create_javadoc works on a given list of files.

          create_javadoc(<VAR>
                         FILES file1 [file2 ...]
                         [CLASSPATH <classpath>]
                         [INSTALLPATH <install path>]
                         [DOCTITLE "the documentation title"]
                         [WINDOWTITLE "the title of the document"]
                         [AUTHOR TRUE|FALSE]
                         [USE TRUE|FALSE]
                         [VERSION TRUE|FALSE]
                        )

       Example:

          create_javadoc(my_example_doc
            FILES ${example_SRCS}
            CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
            WINDOWTITLE "My example"
            DOCTITLE "<h1>My example</h1>"
            AUTHOR TRUE
            USE TRUE
            VERSION TRUE
          )

       Both  signatures  share  most  of the options.  These options are the same as what you can
       find in the javadoc  manpage.   Please  look  at  the  manpage  for  CLASSPATH,  DOCTITLE,
       WINDOWTITLE, AUTHOR, USE and VERSION.

       The documentation will be by default installed to

          ${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>

       if you don't set the INSTALLPATH.

          create_javah(TARGET <target>
                       GENERATED_FILES <VAR>
                       CLASSES <class>...
                       [CLASSPATH <classpath>...]
                       [DEPENDS <depend>...]
                       [OUTPUT_NAME <path>|OUTPUT_DIR <path>]
                       )

       Create  C  header  files  from  java classes. These files provide the connective glue that
       allow your Java and C code to interact.

       There are two main signatures for create_javah.  The  first  signature  returns  generated
       files throught variable specified by GENERATED_FILES option:

          Example:
          Create_javah(GENERATED_FILES files_headers
            CLASSES org.cmake.HelloWorld
            CLASSPATH hello.jar
          )

       The  second  signature  for  create_javah creates a target which encapsulates header files
       generation.

          Example:
          Create_javah(TARGET target_headers
            CLASSES org.cmake.HelloWorld
            CLASSPATH hello.jar
          )

       Both signatures share same options.

          CLASSES <class>...
                 Specifies Java classes used to generate headers.

          CLASSPATH <classpath>...
                 Specifies various paths to look up classes. Here  .class  files,  jar  files  or
                 targets created by command add_jar can be used.

          DEPENDS <depend>...
                 Targets on which the javah target depends

          OUTPUT_NAME <path>
                 Concatenates  the  resulting  header  files for all the classes listed by option
                 CLASSES into <path>. Same behavior as option '-o' of javah tool.

          OUTPUT_DIR <path>
                 Sets the directory where the header files will be generated.  Same  behavior  as
                 option '-d' of javah tool. If not specified, ${CMAKE_CURRENT_BINARY_DIR} is used
                 as output directory.

   UseJavaSymlinks
       Helper script for UseJava.cmake

   UsePkgConfig
       Obsolete pkg-config module for CMake, use FindPkgConfig instead.

       This module defines the following macro:

       PKGCONFIG(package includedir libdir linkflags cflags)

       Calling PKGCONFIG will fill the desired information  into  the  4  given  arguments,  e.g.
       PKGCONFIG(libart-2.0  LIBART_INCLUDE_DIR  LIBART_LINK_DIR LIBART_LINK_FLAGS LIBART_CFLAGS)
       if pkg-config was NOT found or the specified software package doesn't exist, the  variable
       will  be  empty  when  the  function  returns,  otherwise they will contain the respective
       information

   UseSWIG
       Defines the following macros for use with SWIG:

          SWIG_ADD_MODULE(name language [ files ])
            - Define swig module with given name and specified language
          SWIG_LINK_LIBRARIES(name [ libraries ])
            - Link libraries to swig module

       Source files properties  on  module  files  can  be  set  before  the  invocation  of  the
       SWIG_ADD_MODULE macro to specify special behavior of SWIG.

       The source file property CPLUSPLUS calls SWIG in c++ mode, e.g.:

          set_property(SOURCE mymod.i PROPERTY CPLUSPLUS ON)
          swig_add_module(mymod python mymod.i)

       The source file property SWIG_FLAGS adds custom flags to the SWIG executable.

       The source-file property SWIG_MODULE_NAME have to be provided to specify the actual import
       name of the module in the target language if  it  cannot  be  scanned  automatically  from
       source or different from the module file basename.:

          set_property(SOURCE mymod.i PROPERTY SWIG_MODULE_NAME mymod_realname)

       To get the name of the swig module target library, use: ${SWIG_MODULE_${name}_REAL_NAME}.

       Also some variables can be set to specify special behavior of SWIG.

       CMAKE_SWIG_FLAGS can be used to add special flags to all swig calls.

       Another special variable is CMAKE_SWIG_OUTDIR, it allows one to specify where to write all
       the swig generated module (swig -outdir option)

       The name-specific variable SWIG_MODULE_<name>_EXTRA_DEPS may  be  used  to  specify  extra
       dependencies for the generated modules.

       If the source file generated by swig need some special flag you can use:

          set_source_files_properties( ${swig_generated_file_fullname}
                                       PROPERTIES COMPILE_FLAGS "-bla")

   UsewxWidgets
       Convenience include for using wxWidgets library.

       Determines  if  wxWidgets  was  FOUND  and sets the appropriate libs, incdirs, flags, etc.
       INCLUDE_DIRECTORIES and LINK_DIRECTORIES are called.

       USAGE

          # Note that for MinGW users the order of libs is important!
          find_package(wxWidgets REQUIRED net gl core base)
          include(${wxWidgets_USE_FILE})
          # and for each of your dependent executable/library targets:
          target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})

       DEPRECATED

          LINK_LIBRARIES is not called in favor of adding dependencies per target.

   WriteCompilerDetectionHeader
       This module provides the function write_compiler_detection_header().

       The  WRITE_COMPILER_DETECTION_HEADER  function can be used to generate a file suitable for
       preprocessor inclusion which contains macros to be used in source code:

          write_compiler_detection_header(
                    FILE <file>
                    PREFIX <prefix>
                    [OUTPUT_FILES_VAR <output_files_var> OUTPUT_DIR <output_dir>]
                    COMPILERS <compiler> [...]
                    FEATURES <feature> [...]
                    [VERSION <version>]
                    [PROLOG <prolog>]
                    [EPILOG <epilog>]
          )

       The write_compiler_detection_header function generates the file <file> with  macros  which
       all have the prefix <prefix>.

       By  default,  all  content is written directly to the <file>.  The OUTPUT_FILES_VAR may be
       specified to cause the compiler-specific content to be written  to  separate  files.   The
       separate  files  are  then  available in the <output_files_var> and may be consumed by the
       caller for installation for example.  The OUTPUT_DIR specifies a relative  path  from  the
       main <file> to the compiler-specific files. For example:

          write_compiler_detection_header(
            FILE climbingstats_compiler_detection.h
            PREFIX ClimbingStats
            OUTPUT_FILES_VAR support_files
            OUTPUT_DIR compilers
            COMPILERS GNU Clang MSVC
            FEATURES cxx_variadic_templates
          )
          install(FILES
            ${CMAKE_CURRENT_BINARY_DIR}/climbingstats_compiler_detection.h
            DESTINATION include
          )
          install(FILES
            ${support_files}
            DESTINATION include/compilers
          )

       VERSION  may be used to specify the API version to be generated.  Future versions of CMake
       may introduce alternative APIs.  A given API is selected by any  <version>  value  greater
       than  or  equal  to  the  version of CMake that introduced the given API and less than the
       version  of  CMake   that   introduced   its   succeeding   API.    The   value   of   the
       CMAKE_MINIMUM_REQUIRED_VERSION  variable is used if no explicit version is specified.  (As
       of CMake version 3.5.1 there is only one API version.)

       PROLOG may be specified as text content to write at the start of the header. EPILOG may be
       specified as text content to write at the end of the header

       At  least  one  <compiler> and one <feature> must be listed.  Compilers which are known to
       CMake, but not specified are detected and a preprocessor #error is generated for them.   A
       preprocessor macro matching <PREFIX>_COMPILER_IS_<compiler> is generated for each compiler
       known to CMake to contain the value 0 or 1.

       Possible compiler identifiers are documented with the  CMAKE_<LANG>_COMPILER_ID  variable.
       Available  features  in this version of CMake are listed in the CMAKE_C_KNOWN_FEATURES and
       CMAKE_CXX_KNOWN_FEATURES global properties.

       See the cmake-compile-features(7) manual for information on compile features.

   Feature Test Macros
       For    each    compiler,    a     preprocessor     macro     is     generated     matching
       <PREFIX>_COMPILER_IS_<compiler>  which  has  the  content  either 0 or 1, depending on the
       compiler in use.  Preprocessor  macros  for  compiler  version  components  are  generated
       matching      <PREFIX>_COMPILER_VERSION_MAJOR      <PREFIX>_COMPILER_VERSION_MINOR     and
       <PREFIX>_COMPILER_VERSION_PATCH containing decimal values for the  corresponding  compiler
       version components, if defined.

       A  preprocessor  test  is  generated  based  on the compiler version denoting whether each
       feature is enabled.  A  preprocessor  macro  matching  <PREFIX>_COMPILER_<FEATURE>,  where
       <FEATURE>  is  the  upper-case  <feature>  name,  is generated to contain the value 0 or 1
       depending on whether the compiler in use supports the feature:

          write_compiler_detection_header(
            FILE climbingstats_compiler_detection.h
            PREFIX ClimbingStats
            COMPILERS GNU Clang AppleClang MSVC
            FEATURES cxx_variadic_templates
          )

          #if ClimbingStats_COMPILER_CXX_VARIADIC_TEMPLATES
          template<typename... T>
          void someInterface(T t...) { /* ... */ }
          #else
          // Compatibility versions
          template<typename T1>
          void someInterface(T1 t1) { /* ... */ }
          template<typename T1, typename T2>
          void someInterface(T1 t1, T2 t2) { /* ... */ }
          template<typename T1, typename T2, typename T3>
          void someInterface(T1 t1, T2 t2, T3 t3) { /* ... */ }
          #endif

   Symbol Macros
       Some additional symbol-defines are created for particular  features  for  use  as  symbols
       which may be conditionally defined empty:

          class MyClass ClimbingStats_FINAL
          {
              ClimbingStats_CONSTEXPR int someInterface() { return 42; }
          };

       The ClimbingStats_FINAL macro will expand to final if the compiler (and its flags) support
       the cxx_final feature, and the ClimbingStats_CONSTEXPR macro will expand to  constexpr  if
       cxx_constexpr is supported.

       The following features generate corresponding symbol defines:

                   ┌──────────────────────┬───────────────────────────┬─────────────┐
                   │Feature               │ Define                    │ Symbol      │

   Compatibility Implementation Macros
       Some features are  suitable  for  wrapping  in  a  macro  with  a  backward  compatibility
       implementation if the compiler does not support the feature.

       When  the  cxx_static_assert  feature  is  not  provided  by the compiler, a compatibility
       implementation    is    available     via     the     <PREFIX>_STATIC_ASSERT(COND)     and
       <PREFIX>_STATIC_ASSERT_MSG(COND,   MSG)   function-like   macros.  The  macros  expand  to
       static_assert  where  that  compiler  feature  is  available,  and  to   a   compatibility
       implementation  otherwise.  In the first form, the condition is stringified in the message
       field of static_assert.  In the second form, the message MSG  is  passed  to  the  message
       field of static_assert, or ignored if using the backward compatibility implementation.

       The  cxx_attribute_deprecated  feature  provides  a  macro definition <PREFIX>_DEPRECATED,
       which expands to either the  standard  [[deprecated]]  attribute  or  a  compiler-specific
       decorator such as __attribute__((__deprecated__)) used by GNU compilers.

       The  cxx_alignas  feature  provides  a  macro definition <PREFIX>_ALIGNAS which expands to
       either  the  standard  alignas  decorator  or  a  compiler-specific  decorator   such   as
       __attribute__ ((__aligned__)) used by GNU compilers.

       The  cxx_alignof  feature  provides  a  macro definition <PREFIX>_ALIGNOF which expands to
       either the standard alignof decorator or a compiler-specific decorator such as __alignof__
       used by GNU compilers.

                ┌─────────────────────────┬────────────────────────────┬────────────────┐
                │Feature                  │ Define                     │ Symbol         │

       A use-case which arises with such deprecation macros  is  the  deprecation  of  an  entire
       library.   In  that  case,  all  public  API  in  the  library  may  be decorated with the
       <PREFIX>_DEPRECATED macro.  This results in very noisy  build  output  when  building  the
       library itself, so the macro may be may be defined to empty in that case when building the
       deprecated library:

          add_library(compat_support ${srcs})
          target_compile_definitions(compat_support
            PRIVATE
              CompatSupport_DEPRECATED=
          )
