NAME

       cmakeprops - Reference of CMake properties.

PROPERTIES

         CMake Properties - Properties supported by CMake, the Cross-Platform Makefile Generator.

       This  is  the  documentation  for  the  properties supported by CMake. Properties can have
       different scopes. They can either be assigned to a source file, a directory, a  target  or
       globally to CMake. By modifying the values of properties the behaviour of the build system
       can be customized.

PROPERTIES OF GLOBAL SCOPE

       ALLOW_DUPLICATE_CUSTOM_TARGETS
              Allow duplicate custom targets to be created.

              Normally CMake requires that all targets built in a project  have  globally  unique
              logical  names  (see  policy  CMP0002).   This  is necessary to generate meaningful
              project file names in Xcode and VS IDE generators.  It also allows the target names
              to be referenced unambiguously.

              Makefile  generators  are capable of supporting duplicate custom target names.  For
              projects that care only about Makefile generators and do not wish to support  Xcode
              or  VS  IDE generators, one may set this property to true to allow duplicate custom
              targets.  The property allows multiple add_custom_target command calls in different
              directories  to  specify the same target name.  However, setting this property will
              cause non-Makefile generators to produce  an  error  and  refuse  to  generate  the
              project.

       AUTOMOC_TARGETS_FOLDER
              Name  of  FOLDER  for  *_automoc  targets that are added automatically by CMake for
              targets for which AUTOMOC is enabled.

              If not set, CMake uses the FOLDER property of the parent target as a default  value
              for  this  property.  See also the documentation for the FOLDER target property and
              the AUTOMOC target property.

       DEBUG_CONFIGURATIONS
              Specify which configurations are for debugging.

              The value must be a semi-colon separated list of  configuration  names.   Currently
              this   property  is  used  only  by  the  target_link_libraries  command  (see  its
              documentation for details).  Additional uses may be defined in the future.

              This property must be set at the top level of the  project  and  before  the  first
              target_link_libraries  command invocation.  If any entry in the list does not match
              a valid configuration for the project the behavior is undefined.

       DISABLED_FEATURES
              List of features which are disabled during the CMake run.

              List of features which are disabled during the CMake run. By  default  it  contains
              the  names  of  all  packages  which  were  not found. This is determined using the
              <NAME>_FOUND variables. Packages which are searched QUIET are not listed. A project
              can  add  its  own  features  to  this list. This property is used by the macros in
              FeatureSummary.cmake.

       ENABLED_FEATURES
              List of features which are enabled during the CMake run.

              List of features which are enabled during the CMake run. By default it contains the
              names  of  all packages which were found. This is determined using the <NAME>_FOUND
              variables. Packages which are searched QUIET are not listed. A project can add  its
              own   features   to   this   list.   This   property  is  used  by  the  macros  in
              FeatureSummary.cmake.

       ENABLED_LANGUAGES
              Read-only property that contains the list of currently enabled languages

              Set to list of currently enabled languages.

       FIND_LIBRARY_USE_LIB64_PATHS
              Whether FIND_LIBRARY should automatically search lib64 directories.

              FIND_LIBRARY_USE_LIB64_PATHS is  a  boolean  specifying  whether  the  FIND_LIBRARY
              command  should automatically search the lib64 variant of directories called lib in
              the search path when building 64-bit binaries.

       FIND_LIBRARY_USE_OPENBSD_VERSIONING
              Whether FIND_LIBRARY should find OpenBSD-style shared libraries.

              This property is a boolean specifying whether the FIND_LIBRARY command should  find
              shared  libraries  with  OpenBSD-style  versioned extension: ".so.<major>.<minor>".
              The property is set to true on OpenBSD and false on other platforms.

       GLOBAL_DEPENDS_DEBUG_MODE
              Enable global target dependency graph debug mode.

              CMake automatically analyzes  the  global  inter-target  dependency  graph  at  the
              beginning  of  native  build system generation.  This property causes it to display
              details of its analysis to stderr.

       GLOBAL_DEPENDS_NO_CYCLES
              Disallow global target dependency graph cycles.

              CMake automatically analyzes  the  global  inter-target  dependency  graph  at  the
              beginning of native build system generation.  It reports an error if the dependency
              graph contains a cycle that does not consist of all STATIC library  targets.   This
              property  tells  CMake  to  disallow  all  cycles  completely,  even  among  static
              libraries.

       IN_TRY_COMPILE
              Read-only property that is true during a try-compile configuration.

              True when building a project inside a TRY_COMPILE or TRY_RUN command.

       PACKAGES_FOUND
              List of packages which were found during the CMake run.

              List of packages which were found during the CMake run. Whether a package has  been
              found is determined using the <NAME>_FOUND variables.

       PACKAGES_NOT_FOUND
              List of packages which were not found during the CMake run.

              List  of  packages which were not found during the CMake run. Whether a package has
              been found is determined using the <NAME>_FOUND variables.

       PREDEFINED_TARGETS_FOLDER
              Name of FOLDER for targets that are added automatically by CMake.

              If not set, CMake  uses  "CMakePredefinedTargets"  as  a  default  value  for  this
              property.  Targets  such  as  INSTALL, PACKAGE and RUN_TESTS will be organized into
              this FOLDER. See also the documentation for the FOLDER target property.

       REPORT_UNDEFINED_PROPERTIES
              If set, report any undefined properties to this file.

              If this property is set to a filename then when  CMake  runs  it  will  report  any
              properties  or  variables  that  were  accessed  but  not defined into the filename
              specified in this property.

       RULE_LAUNCH_COMPILE
              Specify a launcher for compile rules.

              Makefile generators prefix compiler commands with the given launcher command  line.
              This  is  intended  to  allow  launchers  to  intercept  build  problems  with high
              granularity.  Non-Makefile generators currently ignore this property.

       RULE_LAUNCH_CUSTOM
              Specify a launcher for custom rules.

              Makefile generators prefix custom commands with the given  launcher  command  line.
              This  is  intended  to  allow  launchers  to  intercept  build  problems  with high
              granularity.  Non-Makefile generators currently ignore this property.

       RULE_LAUNCH_LINK
              Specify a launcher for link rules.

              Makefile generators prefix link  and  archive  commands  with  the  given  launcher
              command line.  This is intended to allow launchers to intercept build problems with
              high granularity.  Non-Makefile generators currently ignore this property.

       RULE_MESSAGES
              Specify whether to report a message for each make rule.

              This property specifies whether Makefile generators should add a  progress  message
              describing  what  each  build rule does.  If the property is not set the default is
              ON.  Set the property to OFF to disable granular messages and report only  as  each
              target  completes.   This  is  intended to allow scripted builds to avoid the build
              time cost of detailed reports.  If a CMAKE_RULE_MESSAGES  cache  entry  exists  its
              value  initializes  the  value of this property.  Non-Makefile generators currently
              ignore this property.

       TARGET_ARCHIVES_MAY_BE_SHARED_LIBS
              Set if shared libraries may be named like archives.

              On AIX shared libraries may be named "lib<name>.a".  This property is set  to  true
              on such platforms.

       TARGET_SUPPORTS_SHARED_LIBS
              Does the target platform support shared libraries.

              TARGET_SUPPORTS_SHARED_LIBS  is  a  boolean  specifying whether the target platform
              supports shared libraries. Basically all current general general purpose OS do  so,
              the exception are usually embedded systems with no or special OSs.

       USE_FOLDERS
              Use the FOLDER target property to organize targets into folders.

              If not set, CMake treats this property as OFF by default. CMake generators that are
              capable of organizing into a hierarchy of folders use  the  values  of  the  FOLDER
              target  property  to  name those folders. See also the documentation for the FOLDER
              target property.

       __CMAKE_DELETE_CACHE_CHANGE_VARS_
              Internal property

              Used to detect compiler changes, Do not set.

PROPERTIES ON DIRECTORIES

       ADDITIONAL_MAKE_CLEAN_FILES
              Additional files to clean during the make clean stage.

              A list of files that will be cleaned as a part of the "make clean" stage.

       CACHE_VARIABLES
              List of cache variables available in the current directory.

              This read-only property specifies the  list  of  CMake  cache  variables  currently
              defined.  It is intended for debugging purposes.

       CLEAN_NO_CUSTOM
              Should the output of custom commands be left.

              If  this is true then the outputs of custom commands for this directory will not be
              removed during the "make clean" stage.

       COMPILE_DEFINITIONS
              Preprocessor definitions for compiling a directory's sources.

              The COMPILE_DEFINITIONS property may  be  set  to  a  semicolon-separated  list  of
              preprocessor  definitions  using  the  syntax  VAR  or  VAR=value.   Function-style
              definitions are not supported.  CMake will automatically escape the value correctly
              for the native build system (note that CMake language syntax may require escapes to
              specify some values).  This property may be set on a per-configuration basis  using
              the  name  COMPILE_DEFINITIONS_<CONFIG>  where  <CONFIG> is an upper-case name (ex.
              "COMPILE_DEFINITIONS_DEBUG").  This property will be initialized in each  directory
              by its value in the directory's parent.

              CMake will automatically drop some definitions that are not supported by the native
              build tool.  The VS6 IDE does not support definition values with spaces (but  NMake
              does).

              Disclaimer:  Most native build tools have poor support for escaping certain values.
              CMake has work-arounds for many cases but some values may just not be  possible  to
              pass  correctly.   If a value does not seem to be escaped correctly, do not attempt
              to work-around  the  problem  by  adding  escape  sequences  to  the  value.   Your
              work-around  may  break  in  a  future  version  of  CMake that has improved escape
              support.  Instead consider defining the macro in a (configured) header file.   Then
              report the limitation.  Known limitations include:

                #          - broken almost everywhere
                ;          - broken in VS IDE 7.0 and Borland Makefiles
                ,          - broken in VS IDE
                %          - broken in some cases in NMake
                & |        - broken in some cases on MinGW
                ^ < > \"   - broken in most Make tools on Windows

              CMake  does  not  reject  these values outright because they do work in some cases.
              Use with caution.

       COMPILE_DEFINITIONS_<CONFIG>
              Per-configuration preprocessor definitions in a directory.

              This is the configuration-specific version of COMPILE_DEFINITIONS.   This  property
              will be initialized in each directory by its value in the directory's parent.

       COMPILE_OPTIONS
              List of options to pass to the compiler.

              This  property  specifies  the  list of directories given so far for this property.
              This property exists on directories and targets.

              The target property values are used by the generators to set the  options  for  the
              compiler.

              Contents  of  COMPILE_OPTIONS  may  use  "generator  expressions"  with  the syntax
              "$<...>".  Generator expressions are evaluated during build  system  generation  to
              produce information specific to each build configuration.  Valid expressions are:

                $<0:...>                  = empty string (ignores "...")
                $<1:...>                  = content of "..."
                $<CONFIG:cfg>             = '1' if config is "cfg", else '0'
                $<CONFIGURATION>          = configuration name
                $<BOOL:...>               = '1' if the '...' is true, else '0'
                $<STREQUAL:a,b>           = '1' if a is STREQUAL b, else '0'
                $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
                $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
                $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.
                $<JOIN:list,...>          = joins the list with the content of "..."
                $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
                $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
                $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
                $<C_COMPILER_ID>          = The CMake-id of the C compiler used.
                $<C_COMPILER_ID:comp>     = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
                $<CXX_COMPILER_ID>        = The CMake-id of the CXX compiler used.
                $<CXX_COMPILER_ID:comp>   = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
                $<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
                $<VERSION_LESS:v1,v2>     = '1' if v1 is a version less than v2, else '0'.
                $<VERSION_EQUAL:v1,v2>    = '1' if v1 is the same version as v2, else '0'.
                $<C_COMPILER_VERSION>     = The version of the C compiler used.
                $<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
                $<CXX_COMPILER_VERSION>   = The version of the CXX compiler used.
                $<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
                $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
                $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
                $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

              where  "tgt" is the name of a target.  Target file expressions produce a full path,
              but _DIR and _NAME versions can produce the directory and file name components:

                $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
                $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
                $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

                $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

              Note that tgt is not added as  a  dependency  of  the  target  this  expression  is
              evaluated on.

                $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
                $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

              Boolean expressions:

                $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
                $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
                $<NOT:?>                  = '0' if '?' is '1', else '1'

              where '?' is always either '0' or '1'.

              Expressions with an implicit 'this' target:

                $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.

       DEFINITIONS
              For CMake 2.4 compatibility only.  Use COMPILE_DEFINITIONS instead.

              This  read-only  property  specifies  the  list  of  flags  given  so  far  to  the
              add_definitions  command.   It  is  intended  for  debugging  purposes.   Use   the
              COMPILE_DEFINITIONS instead.

       EXCLUDE_FROM_ALL
              Exclude the directory from the all target of its parent.

              A  property  on  a  directory  that  indicates if its targets are excluded from the
              default build target. If it is not, then with a Makefile for  example  typing  make
              will  cause  the targets to be built. The same concept applies to the default build
              of other generators.

       IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
              Specify #include line transforms for dependencies in a directory.

              This property  specifies  rules  to  transform  macro-like  #include  lines  during
              implicit  dependency scanning of C and C++ source files.  The list of rules must be
              semicolon-separated with each entry of the form  "A_MACRO(%)=value-with-%"  (the  %
              must  be  literal).   During  dependency  scanning  occurrences  of A_MACRO(...) on
              #include lines will be  replaced  by  the  value  given  with  the  macro  argument
              substituted for '%'.  For example, the entry

                MYDIR(%)=<mydir/%>

              will convert lines of the form

                #include MYDIR(myheader.h)

              to

                #include <mydir/myheader.h>

              allowing the dependency to be followed.

              This  property  applies to sources in all targets within a directory.  The property
              value is initialized in each directory by its value in the directory's parent.

       INCLUDE_DIRECTORIES
              List of preprocessor include file search directories.

              This  property  specifies  the  list  of  directories   given   so   far   to   the
              include_directories  command.  This property exists on directories and targets.  In
              addition to accepting values from the include_directories command,  values  may  be
              set  directly  on  any  directory  or any target using the set_property command.  A
              target gets its initial value for this property from the  value  of  the  directory
              property.   A  directory gets its initial value from its parent directory if it has
              one.  Both directory and target property  values  are  adjusted  by  calls  to  the
              include_directories command.

              The  target property values are used by the generators to set the include paths for
              the compiler.  See also the include_directories command.

       INCLUDE_REGULAR_EXPRESSION
              Include file scanning regular expression.

              This read-only property specifies the regular  expression  used  during  dependency
              scanning   to   match   include   files   that   should   be   followed.   See  the
              include_regular_expression command.

       INTERPROCEDURAL_OPTIMIZATION
              Enable interprocedural optimization for targets in a directory.

              If set to true, enables interprocedural optimizations  if  they  are  known  to  be
              supported by the compiler.

       INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
              Per-configuration interprocedural optimization for a directory.

              This  is a per-configuration version of INTERPROCEDURAL_OPTIMIZATION.  If set, this
              property overrides the generic property for the named configuration.

       LINK_DIRECTORIES
              List of linker search directories.

              This read-only property specifies the list of  directories  given  so  far  to  the
              link_directories command.  It is intended for debugging purposes.

       LISTFILE_STACK
              The current stack of listfiles being processed.

              This  property  is mainly useful when trying to debug errors in your CMake scripts.
              It returns a list of what list files are currently being processed, in order. So if
              one  listfile does an INCLUDE command then that is effectively pushing the included
              listfile onto the stack.

       MACROS List of macro commands available in the current directory.

              This read-only property specifies the list of CMake macros currently  defined.   It
              is intended for debugging purposes.  See the macro command.

       PARENT_DIRECTORY
              Source directory that added current subdirectory.

              This  read-only  property  specifies  the  source  directory that added the current
              source directory as a subdirectory of the build.  In the  top-level  directory  the
              value is the empty-string.

       RULE_LAUNCH_COMPILE
              Specify a launcher for compile rules.

              See  the  global  property of the same name for details.  This overrides the global
              property for a directory.

       RULE_LAUNCH_CUSTOM
              Specify a launcher for custom rules.

              See the global property of the same name for details.  This  overrides  the  global
              property for a directory.

       RULE_LAUNCH_LINK
              Specify a launcher for link rules.

              See  the  global  property of the same name for details.  This overrides the global
              property for a directory.

       TEST_INCLUDE_FILE
              A cmake file that will be included when ctest is run.

              If you specify TEST_INCLUDE_FILE, that file will be  included  and  processed  when
              ctest is run on the directory.

       VARIABLES
              List of variables defined in the current directory.

              This  read-only  property  specifies the list of CMake variables currently defined.
              It is intended for debugging purposes.

       VS_GLOBAL_SECTION_POST_<section>
              Specify a postSolution global section in Visual Studio.

              Setting a property like this generates an  entry  of  the  following  form  in  the
              solution file:

                GlobalSection(<section>) = postSolution
                  <contents based on property value>
                EndGlobalSection

              The  property  must  be  set to a semicolon-separated list of key=value pairs. Each
              such pair will be transformed  into  an  entry  in  the  solution  global  section.
              Whitespace  around  key and value is ignored. List elements which do not contain an
              equal sign are skipped.

              This property only works for Visual Studio 7 and above;  it  is  ignored  on  other
              generators.  The property only applies when set on a directory whose CMakeLists.txt
              contains a project() command.

              Note  that  CMake  generates   postSolution   sections   ExtensibilityGlobals   and
              ExtensibilityAddIns  by  default.  If  you  set the corresponding property, it will
              override      the      default      section.       For       example,       setting
              VS_GLOBAL_SECTION_POST_ExtensibilityGlobals  will  override the default contents of
              the ExtensibilityGlobals section, while keeping ExtensibilityAddIns on its default.

       VS_GLOBAL_SECTION_PRE_<section>
              Specify a preSolution global section in Visual Studio.

              Setting a property like this generates an  entry  of  the  following  form  in  the
              solution file:

                GlobalSection(<section>) = preSolution
                  <contents based on property value>
                EndGlobalSection

              The  property  must  be  set to a semicolon-separated list of key=value pairs. Each
              such pair will be transformed  into  an  entry  in  the  solution  global  section.
              Whitespace  around  key and value is ignored. List elements which do not contain an
              equal sign are skipped.

              This property only works for Visual Studio 7 and above;  it  is  ignored  on  other
              generators.  The property only applies when set on a directory whose CMakeLists.txt
              contains a project() command.

PROPERTIES ON TARGETS

       <CONFIG>_OUTPUT_NAME
              Old per-configuration target file base name.

              This is a configuration-specific version of OUTPUT_NAME.  Use  OUTPUT_NAME_<CONFIG>
              instead.

       <CONFIG>_POSTFIX
              Postfix to append to the target file name for configuration <CONFIG>.

              When building with configuration <CONFIG> the value of this property is appended to
              the target file name built on disk.  For non-executable targets, this  property  is
              initialized by the value of the variable CMAKE_<CONFIG>_POSTFIX if it is set when a
              target is created.  This property is ignored on the  Mac  for  Frameworks  and  App
              Bundles.

       <LANG>_VISIBILITY_PRESET
              Value for symbol visibility compile flags

              The  <LANG>_VISIBILITY_PRESET  property determines the value passed in a visibility
              related compile option, such as -fvisibility= for <LANG>.  This property  only  has
              an affect for libraries and executables with exports.  This property is initialized
              by the value of the variable CMAKE_<LANG>_VISIBILITY_PRESET if it  is  set  when  a
              target is created.

       ALIASED_TARGET
              Name of target aliased by this target.

              If this is an ALIAS target, this property contains the name of the target aliased.

       ARCHIVE_OUTPUT_DIRECTORY
              Output directory in which to build ARCHIVE target files.

              This  property  specifies  the  directory into which archive target files should be
              built.  Multi-configuration  generators  (VS,  Xcode)  append  a  per-configuration
              subdirectory  to  the  specified  directory.  There are three kinds of target files
              that may be built: archive, library, and runtime.  Executables are  always  treated
              as  runtime targets. Static libraries are always treated as archive targets. Module
              libraries are always treated as  library  targets.  For  non-DLL  platforms  shared
              libraries  are  treated  as  library  targets.  For DLL platforms the DLL part of a
              shared library is treated as a runtime target and the corresponding import  library
              is treated as an archive target. All Windows-based systems including Cygwin are DLL
              platforms.   This  property  is  initialized  by  the   value   of   the   variable
              CMAKE_ARCHIVE_OUTPUT_DIRECTORY if it is set when a target is created.

       ARCHIVE_OUTPUT_DIRECTORY_<CONFIG>
              Per-configuration output directory for ARCHIVE target files.

              This    is   a   per-configuration   version   of   ARCHIVE_OUTPUT_DIRECTORY,   but
              multi-configuration generators  (VS,  Xcode)  do  NOT  append  a  per-configuration
              subdirectory to the specified directory.  This property is initialized by the value
              of the variable CMAKE_ARCHIVE_OUTPUT_DIRECTORY_<CONFIG> if it is set when a  target
              is created.

       ARCHIVE_OUTPUT_NAME
              Output name for ARCHIVE target files.

              This  property  specifies  the  base  name  for  archive target files. It overrides
              OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties.  There are three kinds  of  target
              files  that  may  be  built: archive, library, and runtime.  Executables are always
              treated as runtime targets. Static libraries are always treated as archive targets.
              Module  libraries  are  always  treated  as  library targets. For non-DLL platforms
              shared libraries are treated as library targets. For DLL platforms the DLL part  of
              a  shared  library  is  treated  as  a  runtime target and the corresponding import
              library is treated as an archive target. All Windows-based systems including Cygwin
              are DLL platforms.

       ARCHIVE_OUTPUT_NAME_<CONFIG>
              Per-configuration output name for ARCHIVE target files.

              This is the configuration-specific version of ARCHIVE_OUTPUT_NAME.

       AUTOMOC
              Should the target be processed with automoc (for Qt projects).

              AUTOMOC  is  a boolean specifying whether CMake will handle the Qt moc preprocessor
              automatically, i.e. without having to  use  the  QT4_WRAP_CPP()  or  QT5_WRAP_CPP()
              macro.  Currently  Qt4  and  Qt5 are supported.  When this property is set to TRUE,
              CMake will scan the source files at build time and invoke moc  accordingly.  If  an
              #include  statement  like  #include  "moc_foo.cpp"  is  found,  the  Q_OBJECT class
              declaration is expected in the header, and moc is run on the  header  file.  If  an
              #include statement like #include "foo.moc" is found, then a Q_OBJECT is expected in
              the current source file and moc is run on the file itself. Additionally, all header
              files  are  parsed for Q_OBJECT macros, and if found, moc is also executed on those
              files. The resulting moc files, which are not included as shown above in any of the
              source  files  are  included in a generated <targetname>_automoc.cpp file, which is
              compiled as part of the target.This property is initialized by  the  value  of  the
              variable CMAKE_AUTOMOC if it is set when a target is created.

              Additional  command  line  options  for  moc can be set via the AUTOMOC_MOC_OPTIONS
              property.

              By setting the CMAKE_AUTOMOC_RELAXED_MODE variable to TRUE the rules for  searching
              the  files which will be processed by moc can be relaxed. See the documentation for
              this variable for more details.

              The global property AUTOMOC_TARGETS_FOLDER can be used to group the automoc targets
              together in an IDE, e.g. in MSVS.

       AUTOMOC_MOC_OPTIONS
              Additional options for moc when using automoc (see the AUTOMOC property)

              This  property is only used if the AUTOMOC property is set to TRUE for this target.
              In this case, it holds additional command line options which will be used when  moc
              is  executed  during  the  build,  i.e.  it  is  equivalent to the optional OPTIONS
              argument of the qt4_wrap_cpp() macro.

              By default it is empty.

       BUILD_WITH_INSTALL_RPATH
              Should build tree targets have install tree rpaths.

              BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the target in  the
              build tree with the INSTALL_RPATH.  This takes precedence over SKIP_BUILD_RPATH and
              avoids the need for relinking before installation.  This property is initialized by
              the value of the variable CMAKE_BUILD_WITH_INSTALL_RPATH if it is set when a target
              is created.

       BUNDLE This target is a CFBundle on the Mac.

              If a module library target has this property set to true it  will  be  built  as  a
              CFBundle when built on the mac. It will have the directory structure required for a
              CFBundle and will be suitable to be used for  creating  Browser  Plugins  or  other
              application resources.

       BUNDLE_EXTENSION
              The file extension used to name a BUNDLE target on the Mac.

              The  default  value  is  "bundle"  -  you  can  also  use "plugin" or whatever file
              extension is required by the host app for your bundle.

       COMPATIBLE_INTERFACE_BOOL
              Properties which must be compatible with their link interface

              The COMPATIBLE_INTERFACE_BOOL property may contain a  list  of  propertiesfor  this
              target which must be consistent when evaluated as a boolean in the INTERFACE of all
              linked dependees.  For example, if a property "FOO" appears in the list,  then  for
              each dependee, the "INTERFACE_FOO" property content in all of its dependencies must
              be consistent with each other,  and  with  the  "FOO"  property  in  the  dependee.
              Consistency in this sense has the meaning that if the property is set, then it must
              have the same boolean value as all others, and if the property is not set, then  it
              is  ignored.  Note that for each dependee, the set of properties from this property
              must not intersect with the set of properties from the  COMPATIBLE_INTERFACE_STRING
              property.

       COMPATIBLE_INTERFACE_STRING
              Properties which must be string-compatible with their link interface

              The  COMPATIBLE_INTERFACE_STRING property may contain a list of properties for this
              target which must be the same when evaluated as a string in the  INTERFACE  of  all
              linked  dependees.   For example, if a property "FOO" appears in the list, then for
              each dependee, the "INTERFACE_FOO" property content in all of its dependencies must
              be  equal  with  each  other,  and with the "FOO" property in the dependee.  If the
              property is not set, then it is ignored.  Note that for each dependee, the  set  of
              properties  from  this  property must not intersect with the set of properties from
              the COMPATIBLE_INTERFACE_BOOL property.

       COMPILE_DEFINITIONS
              Preprocessor definitions for compiling a target's sources.

              The COMPILE_DEFINITIONS property may  be  set  to  a  semicolon-separated  list  of
              preprocessor  definitions  using  the  syntax  VAR  or  VAR=value.   Function-style
              definitions are not supported.  CMake will automatically escape the value correctly
              for the native build system (note that CMake language syntax may require escapes to
              specify some values).  This property may be set on a per-configuration basis  using
              the  name  COMPILE_DEFINITIONS_<CONFIG>  where  <CONFIG> is an upper-case name (ex.
              "COMPILE_DEFINITIONS_DEBUG").

              CMake will automatically drop some definitions that are not supported by the native
              build  tool.  The VS6 IDE does not support definition values with spaces (but NMake
              does).

              Contents of COMPILE_DEFINITIONS may use "generator  expressions"  with  the  syntax
              "$<...>".   Generator  expressions  are evaluated during build system generation to
              produce information specific to each build configuration.  Valid expressions are:

                $<0:...>                  = empty string (ignores "...")
                $<1:...>                  = content of "..."
                $<CONFIG:cfg>             = '1' if config is "cfg", else '0'
                $<CONFIGURATION>          = configuration name
                $<BOOL:...>               = '1' if the '...' is true, else '0'
                $<STREQUAL:a,b>           = '1' if a is STREQUAL b, else '0'
                $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
                $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
                $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.
                $<JOIN:list,...>          = joins the list with the content of "..."
                $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
                $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
                $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
                $<C_COMPILER_ID>          = The CMake-id of the C compiler used.
                $<C_COMPILER_ID:comp>     = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
                $<CXX_COMPILER_ID>        = The CMake-id of the CXX compiler used.
                $<CXX_COMPILER_ID:comp>   = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
                $<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
                $<VERSION_LESS:v1,v2>     = '1' if v1 is a version less than v2, else '0'.
                $<VERSION_EQUAL:v1,v2>    = '1' if v1 is the same version as v2, else '0'.
                $<C_COMPILER_VERSION>     = The version of the C compiler used.
                $<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
                $<CXX_COMPILER_VERSION>   = The version of the CXX compiler used.
                $<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
                $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
                $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
                $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

              where "tgt" is the name of a target.  Target file expressions produce a full  path,
              but _DIR and _NAME versions can produce the directory and file name components:

                $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
                $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
                $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

                $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

              Note  that  tgt  is  not  added  as  a  dependency of the target this expression is
              evaluated on.

                $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
                $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

              Boolean expressions:

                $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
                $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
                $<NOT:?>                  = '0' if '?' is '1', else '1'

              where '?' is always either '0' or '1'.

              Expressions with an implicit 'this' target:

                $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.

              Disclaimer: Most native build tools have poor support for escaping certain  values.
              CMake  has  work-arounds for many cases but some values may just not be possible to
              pass correctly.  If a value does not seem to be escaped correctly, do  not  attempt
              to  work-around  the  problem  by  adding  escape  sequences  to  the  value.  Your
              work-around may break in a  future  version  of  CMake  that  has  improved  escape
              support.   Instead consider defining the macro in a (configured) header file.  Then
              report the limitation.  Known limitations include:

                #          - broken almost everywhere
                ;          - broken in VS IDE 7.0 and Borland Makefiles
                ,          - broken in VS IDE
                %          - broken in some cases in NMake
                & |        - broken in some cases on MinGW
                ^ < > \"   - broken in most Make tools on Windows

              CMake does not reject these values outright because they do  work  in  some  cases.
              Use with caution.

       COMPILE_DEFINITIONS_<CONFIG>
              Per-configuration preprocessor definitions on a target.

              This is the configuration-specific version of COMPILE_DEFINITIONS.

       COMPILE_FLAGS
              Additional flags to use when compiling this target's sources.

              The  COMPILE_FLAGS  property  sets  additional compiler flags used to build sources
              within  the  target.   Use  COMPILE_DEFINITIONS  to  pass  additional  preprocessor
              definitions.

       COMPILE_OPTIONS
              List of options to pass to the compiler.

              This  property  specifies  the  list of options specified so far for this property.
              This property exists on directories and targets.

              The target property values are used by the generators to set the  options  for  the
              compiler.

              Contents  of  COMPILE_OPTIONS  may  use  "generator  expressions"  with  the syntax
              "$<...>".  Generator expressions are evaluated during build  system  generation  to
              produce information specific to each build configuration.  Valid expressions are:

                $<0:...>                  = empty string (ignores "...")
                $<1:...>                  = content of "..."
                $<CONFIG:cfg>             = '1' if config is "cfg", else '0'
                $<CONFIGURATION>          = configuration name
                $<BOOL:...>               = '1' if the '...' is true, else '0'
                $<STREQUAL:a,b>           = '1' if a is STREQUAL b, else '0'
                $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
                $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
                $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.
                $<JOIN:list,...>          = joins the list with the content of "..."
                $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
                $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
                $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
                $<C_COMPILER_ID>          = The CMake-id of the C compiler used.
                $<C_COMPILER_ID:comp>     = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
                $<CXX_COMPILER_ID>        = The CMake-id of the CXX compiler used.
                $<CXX_COMPILER_ID:comp>   = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
                $<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
                $<VERSION_LESS:v1,v2>     = '1' if v1 is a version less than v2, else '0'.
                $<VERSION_EQUAL:v1,v2>    = '1' if v1 is the same version as v2, else '0'.
                $<C_COMPILER_VERSION>     = The version of the C compiler used.
                $<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
                $<CXX_COMPILER_VERSION>   = The version of the CXX compiler used.
                $<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
                $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
                $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
                $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

              where  "tgt" is the name of a target.  Target file expressions produce a full path,
              but _DIR and _NAME versions can produce the directory and file name components:

                $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
                $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
                $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

                $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

              Note that tgt is not added as  a  dependency  of  the  target  this  expression  is
              evaluated on.

                $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
                $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

              Boolean expressions:

                $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
                $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
                $<NOT:?>                  = '0' if '?' is '1', else '1'

              where '?' is always either '0' or '1'.

              Expressions with an implicit 'this' target:

                $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.

       DEBUG_POSTFIX
              See target property <CONFIG>_POSTFIX.

              This  property  is a special case of the more-general <CONFIG>_POSTFIX property for
              the DEBUG configuration.

       DEFINE_SYMBOL
              Define a symbol when compiling this target's sources.

              DEFINE_SYMBOL sets the name of  the  preprocessor  symbol  defined  when  compiling
              sources  in  a  shared library. If not set here then it is set to target_EXPORTS by
              default (with some substitutions if the target is not a valid C  identifier).  This
              is  useful  for  headers  to know whether they are being included from inside their
              library or outside to properly setup dllexport/dllimport decorations.

       ENABLE_EXPORTS
              Specify whether an executable exports symbols for loadable modules.

              Normally an executable does not export any symbols because it is the final program.
              It  is possible for an executable to export symbols to be used by loadable modules.
              When this property is set to true CMake will allow other targets to "link"  to  the
              executable with the TARGET_LINK_LIBRARIES command.  On all platforms a target-level
              dependency on the executable is created for targets  that  link  to  it.   For  DLL
              platforms  an import library will be created for the exported symbols and then used
              for linking.  All Windows-based systems including Cygwin are  DLL  platforms.   For
              non-DLL platforms that require all symbols to be resolved at link time, such as Mac
              OS X, the module will "link" to the executable using a flag like  "-bundle_loader".
              For  other  non-DLL  platforms  the  link  rule is simply ignored since the dynamic
              loader will automatically bind symbols when the module is loaded.

       EXCLUDE_FROM_ALL
              Exclude the target from the all target.

              A property on a target that indicates if the target is excluded  from  the  default
              build target. If it is not, then with a Makefile for example typing make will cause
              this target to be built. The same concept applies to the  default  build  of  other
              generators.  Installing  a  target  with EXCLUDE_FROM_ALL set to true has undefined
              behavior.

       EXCLUDE_FROM_DEFAULT_BUILD
              Exclude target from "Build Solution".

              This property is only used by Visual Studio generators 7 and  above.  When  set  to
              TRUE, the target will not be built when you press "Build Solution".

       EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG>
              Per-configuration version of target exclusion from "Build Solution".

              This  is  the  configuration-specific version of EXCLUDE_FROM_DEFAULT_BUILD. If the
              generic    EXCLUDE_FROM_DEFAULT_BUILD    is    also    set     on     a     target,
              EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG> takes precedence in configurations for which it
              has a value.

       EXPORT_NAME
              Exported name for target files.

              This sets the name for the IMPORTED target generated when  it  this  target  is  is
              exported.  If not set, the logical target name is used by default.

       EchoString
              A message to be displayed when the target is built.

              A  message  to  display  on  some generators (such as makefiles) when the target is
              built.

       FOLDER Set the folder name. Use to organize targets in an IDE.

              Targets with no FOLDER property will appear as top  level  entities  in  IDEs  like
              Visual Studio. Targets with the same FOLDER property value will appear next to each
              other in a folder of that  name.  To  nest  folders,  use  FOLDER  values  such  as
              'GUI/Dialogs' with '/' characters separating folder levels.

       FRAMEWORK
              This target is a framework on the Mac.

              If  a  shared  library  target  has this property set to true it will be built as a
              framework when built on the mac. It will have the directory structure required  for
              a framework and will be suitable to be used with the -framework option

       Fortran_FORMAT
              Set to FIXED or FREE to indicate the Fortran source layout.

              This  property  tells  CMake  whether  the  Fortran  source  files  in a target use
              fixed-format or free-format.  CMake will pass the corresponding format flag to  the
              compiler.   Use the source-specific Fortran_FORMAT property to change the format of
              a specific source file.  If the variable CMAKE_Fortran_FORMAT is set when a  target
              is created its value is used to initialize this property.

       Fortran_MODULE_DIRECTORY
              Specify output directory for Fortran modules provided by the target.

              If  the  target contains Fortran source files that provide modules and the compiler
              supports a module output directory  this  specifies  the  directory  in  which  the
              modules  will  be placed.  When this property is not set the modules will be placed
              in the build directory corresponding to the  target's  source  directory.   If  the
              variable  CMAKE_Fortran_MODULE_DIRECTORY  is set when a target is created its value
              is used to initialize this property.

              Note that some compilers will automatically search the module output directory  for
              modules  USEd  during compilation but others will not.  If your sources USE modules
              their  location  must  be  specified  by  INCLUDE_DIRECTORIES  regardless  of  this
              property.

       GENERATOR_FILE_NAME
              Generator's file for this target.

              An  internal  property used by some generators to record the name of the project or
              dsp file associated with this target. Note that at configure time, this property is
              only set for targets created by include_external_msproject().

       GNUtoMS
              Convert GNU import library (.dll.a) to MS format (.lib).

              When linking a shared library or executable that exports symbols using GNU tools on
              Windows (MinGW/MSYS) with  Visual  Studio  installed  convert  the  import  library
              (.dll.a)  from GNU to MS format (.lib).  Both import libraries will be installed by
              install(TARGETS) and exported by install(EXPORT)  and  export()  to  be  linked  by
              applications with either GNU- or MS-compatible tools.

              If  the variable CMAKE_GNUtoMS is set when a target is created its value is used to
              initialize this property.  The variable must be set prior to the first command that
              enables  a  language  such  as  project() or enable_language().  CMake provides the
              variable as an option to the user automatically when configuring  on  Windows  with
              GNU tools.

       HAS_CXX
              Link the target using the C++ linker tool (obsolete).

              This  is  equivalent  to  setting  the  LINKER_LANGUAGE  property to CXX.  See that
              property's documentation for details.

       IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
              Specify #include line transforms for dependencies in a target.

              This property  specifies  rules  to  transform  macro-like  #include  lines  during
              implicit  dependency scanning of C and C++ source files.  The list of rules must be
              semicolon-separated with each entry of the form  "A_MACRO(%)=value-with-%"  (the  %
              must  be  literal).   During  dependency  scanning  occurrences  of A_MACRO(...) on
              #include lines will be  replaced  by  the  value  given  with  the  macro  argument
              substituted for '%'.  For example, the entry

                MYDIR(%)=<mydir/%>

              will convert lines of the form

                #include MYDIR(myheader.h)

              to

                #include <mydir/myheader.h>

              allowing the dependency to be followed.

              This property applies to sources in the target on which it is set.

       IMPORTED
              Read-only indication of whether a target is IMPORTED.

              The  boolean  value  of this property is true for targets created with the IMPORTED
              option to add_executable or add_library.  It is false for targets built within  the
              project.

       IMPORTED_CONFIGURATIONS
              Configurations provided for an IMPORTED target.

              Set  this to the list of configuration names available for an IMPORTED target.  The
              names correspond to configurations defined in the project from which the target  is
              imported.   If  the  importing  project  uses a different set of configurations the
              names may be mapped using the MAP_IMPORTED_CONFIG_<CONFIG> property.   Ignored  for
              non-imported targets.

       IMPORTED_IMPLIB
              Full path to the import library for an IMPORTED target.

              Set  this  to  the  location  of  the  ".lib"  part  of a windows DLL.  Ignored for
              non-imported targets.

       IMPORTED_IMPLIB_<CONFIG>
              <CONFIG>-specific version of IMPORTED_IMPLIB property.

              Configuration names correspond to those provided by  the  project  from  which  the
              target is imported.

       IMPORTED_LINK_DEPENDENT_LIBRARIES
              Dependent shared libraries of an imported shared library.

              Shared  libraries  may  be  linked  to  other  shared  libraries  as  part of their
              implementation.  On some platforms the linker searches for the dependent  libraries
              of  shared libraries they are including in the link.  Set this property to the list
              of dependent shared libraries of an imported library.  The list should be  disjoint
              from  the list of interface libraries in the INTERFACE_LINK_LIBRARIES property.  On
              platforms requiring dependent shared libraries to be found at link time CMake  uses
              this  list to add appropriate files or paths to the link command line.  Ignored for
              non-imported targets.

       IMPORTED_LINK_DEPENDENT_LIBRARIES_<CONFIG>
              <CONFIG>-specific version of IMPORTED_LINK_DEPENDENT_LIBRARIES.

              Configuration names correspond to those provided by  the  project  from  which  the
              target  is  imported.   If  set,  this  property  completely  overrides the generic
              property for the named configuration.

       IMPORTED_LINK_INTERFACE_LANGUAGES
              Languages compiled into an IMPORTED static library.

              Set this to the list of languages of source files  compiled  to  produce  a  STATIC
              IMPORTED  library  (such as "C" or "CXX").  CMake accounts for these languages when
              computing how to link a target to the imported library.   For  example,  when  a  C
              executable  links to an imported C++ static library CMake chooses the C++ linker to
              satisfy language runtime dependencies of the static library.

              This property is ignored for targets that are not STATIC libraries.  This  property
              is ignored for non-imported targets.

       IMPORTED_LINK_INTERFACE_LANGUAGES_<CONFIG>
              <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LANGUAGES.

              Configuration  names  correspond  to  those  provided by the project from which the
              target is imported.   If  set,  this  property  completely  overrides  the  generic
              property for the named configuration.

       IMPORTED_LINK_INTERFACE_LIBRARIES
              Transitive link interface of an IMPORTED target.

              Set  this  to  the  list  of libraries whose interface is included when an IMPORTED
              library target is linked to another target.  The libraries will be included on  the
              link  line  for  the  target.   Unlike  the LINK_INTERFACE_LIBRARIES property, this
              property applies to all imported target types, including  STATIC  libraries.   This
              property is ignored for non-imported targets.

              This    property    is    ignored    if   the   target   also   has   a   non-empty
              INTERFACE_LINK_LIBRARIES property.

              This property is deprecated. Use INTERFACE_LINK_LIBRARIES instead.

       IMPORTED_LINK_INTERFACE_LIBRARIES_<CONFIG>
              <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LIBRARIES.

              Configuration names correspond to those provided by  the  project  from  which  the
              target  is  imported.   If  set,  this  property  completely  overrides the generic
              property for the named configuration.

              This   property   is   ignored   if   the   target    also    has    a    non-empty
              INTERFACE_LINK_LIBRARIES property.

              This property is deprecated. Use INTERFACE_LINK_LIBRARIES instead.

       IMPORTED_LINK_INTERFACE_MULTIPLICITY
              Repetition count for cycles of IMPORTED static libraries.

              This is LINK_INTERFACE_MULTIPLICITY for IMPORTED targets.

       IMPORTED_LINK_INTERFACE_MULTIPLICITY_<CONFIG>
              <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_MULTIPLICITY.

              If  set,  this  property  completely  overrides  the generic property for the named
              configuration.

       IMPORTED_LOCATION
              Full path to the main file on disk for an IMPORTED target.

              Set this to the location of an IMPORTED target file on disk.  For executables  this
              is  the  location of the executable file.  For bundles on OS X this is the location
              of the executable file inside Contents/MacOS under the application  bundle  folder.
              For  static  libraries  and  modules this is the location of the library or module.
              For shared libraries on non-DLL platforms  this  is  the  location  of  the  shared
              library.   For  frameworks on OS X this is the location of the library file symlink
              just inside the framework folder.  For DLLs this is the location of the ".dll" part
              of  the  library.   For  UNKNOWN  libraries  this is the location of the file to be
              linked.  Ignored for non-imported targets.

              Projects  may  skip  IMPORTED_LOCATION  if  the   configuration-specific   property
              IMPORTED_LOCATION_<CONFIG>  is set.  To get the location of an imported target read
              one of the LOCATION or LOCATION_<CONFIG> properties.

       IMPORTED_LOCATION_<CONFIG>
              <CONFIG>-specific version of IMPORTED_LOCATION property.

              Configuration names correspond to those provided by  the  project  from  which  the
              target is imported.

       IMPORTED_NO_SONAME
              Specifies that an IMPORTED shared library target has no "soname".

              Set  this property to true for an imported shared library file that has no "soname"
              field.  CMake may adjust generated link commands for some platforms to prevent  the
              linker  from using the path to the library in place of its missing soname.  Ignored
              for non-imported targets.

       IMPORTED_NO_SONAME_<CONFIG>
              <CONFIG>-specific version of IMPORTED_NO_SONAME property.

              Configuration names correspond to those provided by  the  project  from  which  the
              target is imported.

       IMPORTED_SONAME
              The "soname" of an IMPORTED target of shared library type.

              Set  this  to  the  "soname"  embedded  in  an  imported  shared  library.  This is
              meaningful only on platforms supporting  the  feature.   Ignored  for  non-imported
              targets.

       IMPORTED_SONAME_<CONFIG>
              <CONFIG>-specific version of IMPORTED_SONAME property.

              Configuration  names  correspond  to  those  provided by the project from which the
              target is imported.

       IMPORT_PREFIX
              What comes before the import library name.

              Similar to the target property PREFIX, but used  for  import  libraries  (typically
              corresponding to a DLL) instead of regular libraries. A target property that can be
              set to override the prefix (such as "lib") on an import library name.

       IMPORT_SUFFIX
              What comes after the import library name.

              Similar to the target property SUFFIX, but used  for  import  libraries  (typically
              corresponding to a DLL) instead of regular libraries. A target property that can be
              set to override the suffix (such as ".lib") on an import library name.

       INCLUDE_DIRECTORIES
              List of preprocessor include file search directories.

              This  property  specifies  the  list  of  directories   given   so   far   to   the
              include_directories  command.  This  property exists on directories and targets. In
              addition to accepting values from the include_directories command,  values  may  be
              set  directly  on  any  directory  or  any target using the set_property command. A
              target gets its initial value for this property from the  value  of  the  directory
              property.  A  directory  gets its initial value from its parent directory if it has
              one. Both directory and target  property  values  are  adjusted  by  calls  to  the
              include_directories command.

              The  target property values are used by the generators to set the include paths for
              the compiler.  See also the include_directories command.

              Contents of INCLUDE_DIRECTORIES may use "generator  expressions"  with  the  syntax
              "$<...>".   Generator  expressions  are evaluated during build system generation to
              produce information specific to each build configuration.  Valid expressions are:

                $<0:...>                  = empty string (ignores "...")
                $<1:...>                  = content of "..."
                $<CONFIG:cfg>             = '1' if config is "cfg", else '0'
                $<CONFIGURATION>          = configuration name
                $<BOOL:...>               = '1' if the '...' is true, else '0'
                $<STREQUAL:a,b>           = '1' if a is STREQUAL b, else '0'
                $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
                $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
                $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.
                $<JOIN:list,...>          = joins the list with the content of "..."
                $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
                $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
                $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
                $<C_COMPILER_ID>          = The CMake-id of the C compiler used.
                $<C_COMPILER_ID:comp>     = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
                $<CXX_COMPILER_ID>        = The CMake-id of the CXX compiler used.
                $<CXX_COMPILER_ID:comp>   = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
                $<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
                $<VERSION_LESS:v1,v2>     = '1' if v1 is a version less than v2, else '0'.
                $<VERSION_EQUAL:v1,v2>    = '1' if v1 is the same version as v2, else '0'.
                $<C_COMPILER_VERSION>     = The version of the C compiler used.
                $<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
                $<CXX_COMPILER_VERSION>   = The version of the CXX compiler used.
                $<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
                $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
                $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
                $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

              where "tgt" is the name of a target.  Target file expressions produce a full  path,
              but _DIR and _NAME versions can produce the directory and file name components:

                $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
                $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
                $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

                $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

              Note  that  tgt  is  not  added  as  a  dependency of the target this expression is
              evaluated on.

                $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
                $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

              Boolean expressions:

                $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
                $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
                $<NOT:?>                  = '0' if '?' is '1', else '1'

              where '?' is always either '0' or '1'.

              Expressions with an implicit 'this' target:

                $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.

       INSTALL_NAME_DIR
              Mac OSX directory name for installed targets.

              INSTALL_NAME_DIR is a string specifying the directory portion of the "install_name"
              field of shared libraries on Mac OSX to use in the installed targets.

       INSTALL_RPATH
              The rpath to use for installed targets.

              A  semicolon-separated  list  specifying the rpath to use in installed targets (for
              platforms that support it).  This property is  initialized  by  the  value  of  the
              variable CMAKE_INSTALL_RPATH if it is set when a target is created.

       INSTALL_RPATH_USE_LINK_PATH
              Add paths to linker search and installed rpath.

              INSTALL_RPATH_USE_LINK_PATH   is  a  boolean  that  if  set  to  true  will  append
              directories in the linker search path and outside the project to the INSTALL_RPATH.
              This    property    is    initialized    by    the    value    of    the   variable
              CMAKE_INSTALL_RPATH_USE_LINK_PATH if it is set when a target is created.

       INTERFACE_COMPILE_DEFINITIONS
              List of public compile definitions for a library.

              Targets may populate this property to publish the compile definitions  required  to
              compile  against  the headers for the target.  Consuming targets can add entries to
              their        own        COMPILE_DEFINITIONS        property         such         as
              $<TARGET_PROPERTY:foo,INTERFACE_COMPILE_DEFINITIONS> to use the compile definitions
              specified in the interface of 'foo'.

              Generator expressions are evaluated  during  build  system  generation  to  produce
              information specific to each build configuration.  Valid expressions are:

                $<0:...>                  = empty string (ignores "...")
                $<1:...>                  = content of "..."

                $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
                $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
                $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
                $<C_COMPILER_ID>          = The CMake-id of the C compiler used.
                $<C_COMPILER_ID:comp>     = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
                $<CXX_COMPILER_ID>        = The CMake-id of the CXX compiler used.
                $<CXX_COMPILER_ID:comp>   = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.

                $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

              where  "tgt" is the name of a target.  Target file expressions produce a full path,
              but _DIR and _NAME versions can produce the directory and file name components:

                $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

              Note that tgt is not added as  a  dependency  of  the  target  this  expression  is
              evaluated on.

                $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
                $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

       INTERFACE_COMPILE_OPTIONS
              List of interface options to pass to the compiler.

              Targets  may  populate  this  property  to  publish the compile options required to
              compile against the headers for the target.  Consuming targets can add  entries  to

              $<TARGET_PROPERTY:foo,INTERFACE_COMPILE_OPTIONS>  to  use   the   compile   options
              specified in the interface of 'foo'.

              Generator  expressions  are  evaluated  during  build  system generation to produce

       INTERFACE_LINK_LIBRARIES
              List public interface libraries for a library.

       INTERFACE_POSITION_INDEPENDENT_CODE
              Whether consumers need to create a position-independent target

              The INTERFACE_POSITION_INDEPENDENT_CODE property informs consumers of  this  target
              whether  they  must  set  their  POSITION_INDEPENDENT_CODE property to ON.  If this
              property is set to ON, then the POSITION_INDEPENDENT_CODE property on all consumers
              will  be  set  to  ON.   Similarly,  if  this  property  is  set  to  OFF, then the
              POSITION_INDEPENDENT_CODE property on all consumers will be set to  OFF.   If  this
              property     is     undefined,     then     consumers    will    determine    their
              POSITION_INDEPENDENT_CODE property by other means.  Consumers must ensure that  the
              targets   that   they   link   to   have   a   consistent   requirement  for  their
              INTERFACE_POSITION_INDEPENDENT_CODE property.

       INTERFACE_SYSTEM_INCLUDE_DIRECTORIES
              List of public system include directories for a library.

              Targets may populate this property to publish the include directories which contain
              system  headers,  and  therefore should not result in compiler warnings.  Consuming
              targets will then mark the same include directories as system headers.

              built.  Multi-configuration  generators  (VS,  Xcode)  append  a  per-configuration
              subdirectory  to  the  specified  directory.  There are three kinds of target files
              that may be built: archive, library, and runtime.  Executables are  always  treated
              as  runtime targets. Static libraries are always treated as archive targets. Module
              libraries are always treated as  library  targets.  For  non-DLL  platforms  shared
              libraries  are  treated  as  library  targets.  For DLL platforms the DLL part of a
              shared library is treated as a runtime target and the corresponding import  library
              is treated as an archive target. All Windows-based systems including Cygwin are DLL
              platforms.   This  property  is  initialized  by  the   value   of   the   variable
              CMAKE_LIBRARY_OUTPUT_DIRECTORY if it is set when a target is created.

       LIBRARY_OUTPUT_DIRECTORY_<CONFIG>
              Per-configuration output directory for LIBRARY target files.

              This    is   a   per-configuration   version   of   LIBRARY_OUTPUT_DIRECTORY,   but
              multi-configuration generators  (VS,  Xcode)  do  NOT  append  a  per-configuration
              subdirectory to the specified directory.  This property is initialized by the value
              of the variable CMAKE_LIBRARY_OUTPUT_DIRECTORY_<CONFIG> if it is set when a  target
              is created.

       LIBRARY_OUTPUT_NAME
              Output name for LIBRARY target files.

              This  property  specifies  the  base  name  for  library target files. It overrides
              OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties.  There are three kinds  of  target
              files  that  may  be  built: archive, library, and runtime.  Executables are always
              treated as runtime targets. Static libraries are always treated as archive targets.
              Module  libraries  are  always  treated  as  library targets. For non-DLL platforms
              shared libraries are treated as library targets. For DLL platforms the DLL part  of
              a  shared  library  is  treated  as  a  runtime target and the corresponding import
              library is treated as an archive target. All Windows-based systems including Cygwin
              are DLL platforms.

       LIBRARY_OUTPUT_NAME_<CONFIG>
              Per-configuration output name for LIBRARY target files.

              This is the configuration-specific version of LIBRARY_OUTPUT_NAME.

       LINKER_LANGUAGE
              Specifies language whose compiler will invoke the linker.

              For  executables,  shared  libraries,  and  modules,  this  sets the language whose
              compiler is used to link the target (such as "C" or "CXX").  A typical value for an
              executable  is  the  language  of the source file providing the program entry point
              (main).  If not set, the language with the highest linker preference value  is  the
              default.  See documentation of CMAKE_<LANG>_LINKER_PREFERENCE variables.

              If  this property is not set by the user, it will be calculated at generate-time by
              CMake.

       LINK_DEPENDS
              Additional files on which a target binary depends for linking.

              Specifies a semicolon-separated list of full-paths to files on which the link  rule
              for  this  target  depends.   The  target binary will be linked if any of the named
              files is newer than it.

              This property is ignored by non-Makefile generators.  It  is  intended  to  specify
              dependencies on "linker scripts" for custom Makefile link rules.

       LINK_DEPENDS_NO_SHARED
              Do not depend on linked shared library files.

              Set  this  property  to  true  to  tell  CMake  generators  not  to  add file-level
              dependencies on the shared library files linked by this  target.   Modification  to
              the  shared  libraries  will  not  be  sufficient  to re-link this target.  Logical
              target-level dependencies will not be affected so the linked shared libraries  will
              still be brought up to date before this target is built.

              This    property    is    initialized    by    the    value    of    the   variable
              CMAKE_LINK_DEPENDS_NO_SHARED if it is set when a target is created.

       LINK_FLAGS
              Additional flags to use when linking this target.

              The LINK_FLAGS property can be used to add extra  flags  to  the  link  step  of  a
              target.  LINK_FLAGS_<CONFIG>  will  add to the configuration <CONFIG>, for example,
              DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO.

       LINK_FLAGS_<CONFIG>
              Per-configuration linker flags for a target.

              This is the configuration-specific version of LINK_FLAGS.

       LINK_INTERFACE_LIBRARIES
              List public interface libraries for a shared library or executable.

              By default linking to a shared library target transitively links  to  targets  with
              which  the  library  itself  was  linked.   For an executable with exports (see the
              ENABLE_EXPORTS property) no default transitive link dependencies  are  used.   This
              property  replaces  the default transitive link dependencies with an explicit list.
              When the target is linked into another target the libraries listed (and recursively
              their  link interface libraries) will be provided to the other target also.  If the
              list is empty then no transitive link dependencies will be incorporated  when  this
              target  is  linked  into another target even if the default set is non-empty.  This
              property is initialized by the value of the variable CMAKE_LINK_INTERFACE_LIBRARIES
              if  it  is  set  when  a  target  is  created.  This property is ignored for STATIC
              libraries.

              This property is overridden by  the  INTERFACE_LINK_LIBRARIES  property  if  policy
              CMP0022 is NEW.

              This property is deprecated. Use INTERFACE_LINK_LIBRARIES instead.

       LINK_INTERFACE_LIBRARIES_<CONFIG>
              Per-configuration list of public interface libraries for a target.

              This  is  the  configuration-specific version of LINK_INTERFACE_LIBRARIES.  If set,
              this  property  completely  overrides  the   generic   property   for   the   named
              configuration.

              This  property  is  overridden  by  the INTERFACE_LINK_LIBRARIES property if policy
              CMP0022 is NEW.

              This property is deprecated. Use INTERFACE_LINK_LIBRARIES instead.

       LINK_INTERFACE_MULTIPLICITY
              Repetition count for STATIC libraries with cyclic dependencies.

              When linking to a STATIC library target with cyclic  dependencies  the  linker  may
              need  to  scan  more  than  once  through  the  archives  in the strongly connected
              component of the dependency graph.  CMake by default constructs the  link  line  so
              that  the  linker  will  scan  through the component at least twice.  This property
              specifies the minimum number of scans if it is larger than the default.  CMake uses
              the largest value specified by any target in a component.

       LINK_INTERFACE_MULTIPLICITY_<CONFIG>
              Per-configuration repetition count for cycles of STATIC libraries.

              This is the configuration-specific version of LINK_INTERFACE_MULTIPLICITY.  If set,
              this  property  completely  overrides  the   generic   property   for   the   named
              configuration.

       LINK_LIBRARIES
              List of direct link dependencies.

              This  property  specifies  the  list of libraries or targets which will be used for
              linking. In addition to accepting values from  the  target_link_libraries  command,
              values may be set directly on any target using the set_property command.

              The target property values are used by the generators to set the link libraries for
              the compiler.  See also the target_link_libraries command.

              Contents  of  LINK_LIBRARIES  may  use  "generator  expressions"  with  the  syntax
              "$<...>".   Generator  expressions  are evaluated during build system generation to
              produce information specific to each build configuration.  Valid expressions are:

                $<0:...>                  = empty string (ignores "...")
                $<1:...>                  = content of "..."
                $<CONFIG:cfg>             = '1' if config is "cfg", else '0'
                $<CONFIGURATION>          = configuration name
                $<BOOL:...>               = '1' if the '...' is true, else '0'
                $<STREQUAL:a,b>           = '1' if a is STREQUAL b, else '0'
                $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
                $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
                $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.
                $<JOIN:list,...>          = joins the list with the content of "..."
                $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
                $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
                $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
                $<C_COMPILER_ID>          = The CMake-id of the C compiler used.
                $<C_COMPILER_ID:comp>     = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
                $<CXX_COMPILER_ID>        = The CMake-id of the CXX compiler used.
                $<CXX_COMPILER_ID:comp>   = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
                $<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
                $<VERSION_LESS:v1,v2>     = '1' if v1 is a version less than v2, else '0'.
                $<VERSION_EQUAL:v1,v2>    = '1' if v1 is the same version as v2, else '0'.
                $<C_COMPILER_VERSION>     = The version of the C compiler used.
                $<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
                $<CXX_COMPILER_VERSION>   = The version of the CXX compiler used.
                $<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
                $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
                $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
                $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

              where "tgt" is the name of a target.  Target file expressions produce a full  path,
              but _DIR and _NAME versions can produce the directory and file name components:

                $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
                $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
                $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

                $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

              Note  that  tgt  is  not  added  as  a  dependency of the target this expression is
              evaluated on.

                $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
                $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

              Boolean expressions:

                $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
                $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
                $<NOT:?>                  = '0' if '?' is '1', else '1'

              where '?' is always either '0' or '1'.

              Expressions with an implicit 'this' target:

                $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.

       LINK_SEARCH_END_STATIC
              End a link line such that static system libraries are used.

              Some linkers support switches such as -Bstatic and -Bdynamic to  determine  whether
              to  use  static or shared libraries for -lXXX options.  CMake uses these options to
              set the link type for libraries whose full paths are not known or (in  some  cases)
              are in implicit link directories for the platform.  By default CMake adds an option
              at the end of the library list (if necessary) to set the linker search type back to
              its starting type.  This property switches the final linker search type to -Bstatic
              regardless of how it started.  See also LINK_SEARCH_START_STATIC.

       LINK_SEARCH_START_STATIC
              Assume the linker looks for static libraries by default.

              Some linkers support switches such as -Bstatic and -Bdynamic to  determine  whether
              to  use  static or shared libraries for -lXXX options.  CMake uses these options to
              set the link type for libraries whose full paths are not known or (in  some  cases)
              are  in  implicit  link directories for the platform.  By default the linker search
              type is assumed to be -Bdynamic  at  the  beginning  of  the  library  list.   This
              property  switches the assumption to -Bstatic.  It is intended for use when linking
              an  executable  statically  (e.g.  with  the  GNU  -static   option).    See   also
              LINK_SEARCH_END_STATIC.

       LOCATION
              Read-only location of a target on disk.

              For  an  imported  target,  this  read-only  property  returns  the  value  of  the
              LOCATION_<CONFIG> property for an unspecified configuration  <CONFIG>  provided  by
              the target.

              For  a  non-imported target, this property is provided for compatibility with CMake
              2.4 and below.  It was meant to get the location of an executable  target's  output
              file  for  use in add_custom_command.  The path may contain a build-system-specific
              portion that is replaced at build time with the configuration getting  built  (such
              as  "$(ConfigurationName)"  in  VS).  In  CMake  2.6  and  above add_custom_command
              automatically recognizes a target name in  its  COMMAND  and  DEPENDS  options  and
              computes  the  target  location.   In  CMake  2.8.4  and  above  add_custom_command
              recognizes generator expressions to refer  to  target  locations  anywhere  in  the
              command.  Therefore this property is not needed for creating custom commands.

              Do  not  set  properties  that  affect  the location of a target after reading this
              property.       These      include      properties      whose      names      match
              "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?",
              "(IMPLIB_)?(PREFIX|SUFFIX)", or "LINKER_LANGUAGE".  Failure to follow this rule  is
              not diagnosed and leaves the location of the target undefined.

       LOCATION_<CONFIG>
              Read-only property providing a target location on disk.

              A  read-only  property that indicates where a target's main file is located on disk
              for the configuration <CONFIG>.  The property  is  defined  only  for  library  and
              executable  targets.   An  imported  target  may  provide  a  set of configurations
              different from that of the importing  project.   By  default  CMake  looks  for  an
              exact-match  but  otherwise  uses  an  arbitrary  available configuration.  Use the
              MAP_IMPORTED_CONFIG_<CONFIG> property to map imported configurations explicitly.

              Do not set properties that affect the location  of  a  target  after  reading  this
              property.       These      include      properties      whose      names      match
              "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?",
              "(IMPLIB_)?(PREFIX|SUFFIX)",  or "LINKER_LANGUAGE".  Failure to follow this rule is
              not diagnosed and leaves the location of the target undefined.

       MACOSX_BUNDLE
              Build an executable as an application bundle on Mac OS X.

              When this property is set to true the executable when built on Mac  OS  X  will  be
              created  as  an  application  bundle.   This  makes it a GUI executable that can be
              launched from the Finder.  See the  MACOSX_BUNDLE_INFO_PLIST  target  property  for
              information about creation of the Info.plist file for the application bundle.  This
              property is initialized by the value of the variable CMAKE_MACOSX_BUNDLE if  it  is
              set when a target is created.

       MACOSX_BUNDLE_INFO_PLIST
              Specify a custom Info.plist template for a Mac OS X App Bundle.

              An  executable  target  with  MACOSX_BUNDLE enabled will be built as an application
              bundle on Mac OS X.  By default its Info.plist file is  created  by  configuring  a
              template  called  MacOSXBundleInfo.plist.in located in the CMAKE_MODULE_PATH.  This
              property specifies an alternative template file name which may be a full path.

              The following target properties may be set to specify content to be configured into
              the file:

                MACOSX_BUNDLE_INFO_STRING
                MACOSX_BUNDLE_ICON_FILE
                MACOSX_BUNDLE_GUI_IDENTIFIER
                MACOSX_BUNDLE_LONG_VERSION_STRING
                MACOSX_BUNDLE_BUNDLE_NAME
                MACOSX_BUNDLE_SHORT_VERSION_STRING
                MACOSX_BUNDLE_BUNDLE_VERSION
                MACOSX_BUNDLE_COPYRIGHT

              CMake  variables  of  the same name may be set to affect all targets in a directory
              that do not have each specific property set.  If a custom Info.plist  is  specified
              by  this  property it may of course hard-code all the settings instead of using the
              target properties.

       MACOSX_FRAMEWORK_INFO_PLIST
              Specify a custom Info.plist template for a Mac OS X Framework.

              A library target with FRAMEWORK enabled will be built as a framework on Mac  OS  X.
              By  default  its  Info.plist  file  is  created  by  configuring  a template called
              MacOSXFrameworkInfo.plist.in  located  in  the  CMAKE_MODULE_PATH.   This  property
              specifies an alternative template file name which may be a full path.

              The following target properties may be set to specify content to be configured into
              the file:

                MACOSX_FRAMEWORK_ICON_FILE
                MACOSX_FRAMEWORK_IDENTIFIER
                MACOSX_FRAMEWORK_SHORT_VERSION_STRING
                MACOSX_FRAMEWORK_BUNDLE_VERSION

              CMake variables of the same name may be set to affect all targets  in  a  directory
              that  do  not have each specific property set.  If a custom Info.plist is specified
              by this property it may of course hard-code all the settings instead of  using  the
              target properties.

       MACOSX_RPATH
              Whether to use rpaths on Mac OS X.

              When this property is set to true, the directory portion of the"install_name" field
              of shared libraries will default to "@rpath".Runtime paths will also be embedded in
              binaries  using  this  target.This  property  is  initialized  by  the value of the
              variable CMAKE_MACOSX_RPATH if it is set when a target is created.

       MAP_IMPORTED_CONFIG_<CONFIG>
              Map from project configuration to IMPORTED target's configuration.

              Set this to the list of configurations of an imported target that may be  used  for
              the  current  project's  <CONFIG>  configuration.   Targets  imported  from another
              project may not provide the same  set  of  configuration  names  available  in  the
              current  project.   Setting  this property tells CMake what imported configurations
              are  suitable  for  use  when  building  the  <CONFIG>  configuration.   The  first
              configuration  in the list found to be provided by the imported target is selected.
              If this property is set and no matching  configurations  are  available,  then  the
              imported  target  is  considered  to  be  not  found.  This property is ignored for
              non-imported targets.

       NAME   Logical name for the target.

              Read-only logical name for the target as used by CMake.

       NO_SONAME
              Whether to set "soname" when linking a shared library or module.

              Enable this boolean property if a generated shared library  or  module  should  not
              have  "soname"  set. Default is to set "soname" on all shared libraries and modules
              as long as the platform supports it. Generally, use this  property  only  for  leaf
              private  libraries or plugins. If you use it on normal shared libraries which other
              targets link against, on some platforms a linker will insert a  full  path  to  the
              library  (as  specified  at  link  time)  into the dynamic section of the dependent
              binary. Therefore, once installed, dynamic loader may eventually fail to locate the
              library for the binary.

       OSX_ARCHITECTURES
              Target specific architectures for OS X.

              The  OSX_ARCHITECTURES  property sets the target binary architecture for targets on
              OS  X.   This  property   is   initialized   by   the   value   of   the   variable
              CMAKE_OSX_ARCHITECTURES   if   it   is   set   when   a  target  is  created.   Use
              OSX_ARCHITECTURES_<CONFIG> to set the binary architectures on  a  per-configuration
              basis.  <CONFIG> is an upper-case name (ex: "OSX_ARCHITECTURES_DEBUG").

       OSX_ARCHITECTURES_<CONFIG>
              Per-configuration OS X binary architectures for a target.

              This property is the configuration-specific version of OSX_ARCHITECTURES.

       OUTPUT_NAME
              Output name for target files.

              This  sets  the  base  name  for  output files created for an executable or library
              target.  If not set, the logical target name is used by default.

       OUTPUT_NAME_<CONFIG>
              Per-configuration target file base name.

              This is the configuration-specific version of OUTPUT_NAME.

       PDB_NAME
              Output name for MS debug symbols .pdb file from linker.

              Set the base name for debug symbols  file  created  for  an  executable  or  shared
              library target.  If not set, the logical target name is used by default.

              This property is not implemented by the Visual Studio 6 generator.

       PDB_NAME_<CONFIG>
              Per-configuration name for MS debug symbols .pdb file.

              This is the configuration-specific version of PDB_NAME.

              This property is not implemented by the Visual Studio 6 generator.

       PDB_OUTPUT_DIRECTORY
              Output directory for MS debug symbols .pdb file from linker.

              This  property  specifies  the  directory  into  which the MS debug symbols will be
              placed by the linker.  This property is initialized by the value  of  the  variable
              CMAKE_PDB_OUTPUT_DIRECTORY if it is set when a target is created.

              This property is not implemented by the Visual Studio 6 generator.

       PDB_OUTPUT_DIRECTORY_<CONFIG>
              Per-configuration output directory for MS debug symbols .pdb files.

              This    is    a    per-configuration    version    of   PDB_OUTPUT_DIRECTORY,   but
              multi-configuration generators  (VS,  Xcode)  do  NOT  append  a  per-configuration
              subdirectory  to the specified directory. This property is initialized by the value
              of the variable CMAKE_PDB_OUTPUT_DIRECTORY_<CONFIG> if it is set when a  target  is
              created.

              This property is not implemented by the Visual Studio 6 generator.

       POSITION_INDEPENDENT_CODE
              Whether to create a position-independent target

              The  POSITION_INDEPENDENT_CODE  property  determines  whether  position independent
              executables or shared libraries will be created.  This property is true by  default
              for  SHARED  and  MODULE  library  targets  and  false otherwise.  This property is
              initialized by the value of the variable CMAKE_POSITION_INDEPENDENT_CODE if  it  is
              set when a target is created.

       POST_INSTALL_SCRIPT
              Deprecated install support.

              The  PRE_INSTALL_SCRIPT  and  POST_INSTALL_SCRIPT  properties  are  the  old way to
              specify CMake scripts to run before and after installing a target.  They  are  used
              only  when  the old INSTALL_TARGETS command is used to install the target.  Use the
              INSTALL command instead.

       PREFIX What comes before the library name.

              A target property that can be set to override the  prefix  (such  as  "lib")  on  a
              library name.

       PRE_INSTALL_SCRIPT
              Deprecated install support.

              The  PRE_INSTALL_SCRIPT  and  POST_INSTALL_SCRIPT  properties  are  the  old way to
              specify CMake scripts to run before and after installing a target.  They  are  used
              only  when  the old INSTALL_TARGETS command is used to install the target.  Use the
              INSTALL command instead.

       PRIVATE_HEADER
              Specify private header files in a FRAMEWORK shared library target.

              Shared library targets marked with the FRAMEWORK property generate frameworks on OS
              X  and  normal  shared libraries on other platforms.  This property may be set to a
              list of header files to be  placed  in  the  PrivateHeaders  directory  inside  the
              framework  folder.  On non-Apple platforms these headers may be installed using the
              PRIVATE_HEADER option to the install(TARGETS) command.

       PROJECT_LABEL
              Change the name of a target in an IDE.

              Can be used to change the name of the target in an IDE like Visual Studio.

       PUBLIC_HEADER
              Specify public header files in a FRAMEWORK shared library target.

              Shared library targets marked with the FRAMEWORK property generate frameworks on OS
              X  and  normal  shared libraries on other platforms.  This property may be set to a
              list of header files to be placed in the Headers  directory  inside  the  framework
              folder.    On  non-Apple  platforms  these  headers  may  be  installed  using  the
              PUBLIC_HEADER option to the install(TARGETS) command.

       RESOURCE
              Specify resource files in a FRAMEWORK shared library target.

              Shared library targets marked with the FRAMEWORK property generate frameworks on OS
              X  and  normal  shared libraries on other platforms.  This property may be set to a
              list of files to be placed in the Resources directory inside the framework  folder.
              On  non-Apple  platforms  these files may be installed using the RESOURCE option to
              the install(TARGETS) command.

       RULE_LAUNCH_COMPILE
              Specify a launcher for compile rules.

              See the global property of the same name for details.  This  overrides  the  global
              and directory property for a target.

       RULE_LAUNCH_CUSTOM
              Specify a launcher for custom rules.

              See  the  global  property of the same name for details.  This overrides the global
              and directory property for a target.

       RULE_LAUNCH_LINK
              Specify a launcher for link rules.

              See the global property of the same name for details.  This  overrides  the  global
              and directory property for a target.

       RUNTIME_OUTPUT_DIRECTORY
              Output directory in which to build RUNTIME target files.

              This  property  specifies  the  directory into which runtime target files should be
              built.  Multi-configuration  generators  (VS,  Xcode)  append  a  per-configuration
              subdirectory  to  the  specified  directory.  There are three kinds of target files
              that may be built: archive, library, and runtime.  Executables are  always  treated
              as  runtime targets. Static libraries are always treated as archive targets. Module
              libraries are always treated as  library  targets.  For  non-DLL  platforms  shared
              libraries  are  treated  as  library  targets.  For DLL platforms the DLL part of a
              shared library is treated as a runtime target and the corresponding import  library
              is treated as an archive target. All Windows-based systems including Cygwin are DLL
              platforms.   This  property  is  initialized  by  the   value   of   the   variable
              CMAKE_RUNTIME_OUTPUT_DIRECTORY if it is set when a target is created.

       RUNTIME_OUTPUT_DIRECTORY_<CONFIG>
              Per-configuration output directory for RUNTIME target files.

              This    is   a   per-configuration   version   of   RUNTIME_OUTPUT_DIRECTORY,   but
              multi-configuration generators  (VS,  Xcode)  do  NOT  append  a  per-configuration
              subdirectory to the specified directory.  This property is initialized by the value
              of the variable CMAKE_RUNTIME_OUTPUT_DIRECTORY_<CONFIG> if it is set when a  target
              is created.

       RUNTIME_OUTPUT_NAME
              Output name for RUNTIME target files.

              This  property  specifies  the  base  name  for runtime target files.  It overrides
              OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties.  There are three kinds  of  target
              files  that  may  be  built: archive, library, and runtime.  Executables are always
              treated as runtime targets. Static libraries are always treated as archive targets.
              Module  libraries  are  always  treated  as  library targets. For non-DLL platforms
              shared libraries are treated as library targets. For DLL platforms the DLL part  of
              a  shared  library  is  treated  as  a  runtime target and the corresponding import
              library is treated as an archive target. All Windows-based systems including Cygwin
              are DLL platforms.

       RUNTIME_OUTPUT_NAME_<CONFIG>
              Per-configuration output name for RUNTIME target files.

              This is the configuration-specific version of RUNTIME_OUTPUT_NAME.

       SKIP_BUILD_RPATH
              Should rpaths be used for the build tree.

              SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic generation of an
              rpath allowing the target to run from the build tree.  This property is initialized
              by  the  value of the variable CMAKE_SKIP_BUILD_RPATH if it is set when a target is
              created.

       SOURCES
              Source names specified for a target.

              Read-only list of sources specified for a target.  The names returned are  suitable
              for passing to the set_source_files_properties command.

       SOVERSION
              What version number is this target.

              For shared libraries VERSION and SOVERSION can be used to specify the build version
              and API version respectively. When building or installing appropriate symlinks  are
              created if the platform supports symlinks and the linker supports so-names. If only
              one of both is specified the missing is assumed to have the  same  version  number.
              SOVERSION  is  ignored  if  NO_SONAME  property  is  set.  For shared libraries and
              executables on Windows the VERSION attribute is parsed to extract  a  "major.minor"
              version number. These numbers are used as the image version of the binary.

       STATIC_LIBRARY_FLAGS
              Extra flags to use when linking static libraries.

              Extra flags to use when linking a static library.

       STATIC_LIBRARY_FLAGS_<CONFIG>
              Per-configuration flags for creating a static library.

              This is the configuration-specific version of STATIC_LIBRARY_FLAGS.

       SUFFIX What comes after the target name.

              A  target property that can be set to override the suffix (such as ".so" or ".exe")
              on the name of a library, module or executable.

       TYPE   The type of the target.

              This read-only property can be used to test the type of the given target.  It  will
              be  one of STATIC_LIBRARY, MODULE_LIBRARY, SHARED_LIBRARY, EXECUTABLE or one of the
              internal target types.

       VERSION
              What version number is this target.

              For shared libraries VERSION and SOVERSION can be used to specify the build version
              and  API version respectively. When building or installing appropriate symlinks are
              created if the platform supports symlinks and the linker supports so-names. If only
              one  of  both  is specified the missing is assumed to have the same version number.
              For executables VERSION can be used to specify the build version. When building  or
              installing  appropriate symlinks are created if the platform supports symlinks. For
              shared libraries and executables on Windows the  VERSION  attribute  is  parsed  to
              extract a "major.minor" version number. These numbers are used as the image version
              of the binary.

       VISIBILITY_INLINES_HIDDEN
              Whether to add a compile flag to hide symbols of inline functions

              The VISIBILITY_INLINES_HIDDEN property determines whether a flag for hiding symbols
              for inline functions. the value passed used in a visibility related compile option,
              such as -fvisibility=.   This  property  only  has  an  affect  for  libraries  and
              executables  with  exports.   This  property  is  initialized  by  the value of the
              variable CMAKE_VISIBILITY_INLINES_HIDDEN if it is set when a target is created.

       VS_DOTNET_REFERENCES
              Visual Studio managed project .NET references

              Adds one or more semicolon-delimited .NET references to a generated  Visual  Studio
              project. For example, "System;System.Windows.Forms".

       VS_DOTNET_TARGET_FRAMEWORK_VERSION
              Specify the .NET target framework version.

              Used to specify the .NET target framework version for C++/CLI. For example, "v4.5".

       VS_GLOBAL_<variable>
              Visual Studio project-specific global variable.

              Tell the Visual Studio generator to set the global variable '<variable>' to a given
              value in the generated Visual Studio  project.  Ignored  on  other  generators.  Qt
              integration works better if VS_GLOBAL_QtVersion is set to the version FindQt4.cmake
              found. For example, "4.7.3"

       VS_GLOBAL_KEYWORD
              Visual Studio project keyword.

              Sets the "keyword" attribute for a generated Visual  Studio  project.  Defaults  to
              "Win32Proj".  You may wish to override this value with "ManagedCProj", for example,
              in a Visual Studio managed C++ unit test project.

       VS_GLOBAL_PROJECT_TYPES
              Visual Studio project type(s).

              Can be set to one or more UUIDs recognized by Visual Studio to indicate the type of
              project. This value is copied verbatim into the generated project file. Example for
              a managed C++ unit testing project:

               {3AC096D0-A1C2-E12C-1390-A8335801FDAB};{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}

              UUIDs are semicolon-delimited.

       VS_GLOBAL_ROOTNAMESPACE
              Visual Studio project root namespace.

              Sets the "RootNamespace" attribute for a  generated  Visual  Studio  project.   The
              attribute will be generated only if this is set.

       VS_KEYWORD
              Visual Studio project keyword.

              Can  be  set  to change the visual studio keyword, for example Qt integration works
              better if this is set to Qt4VSv1.0.

       VS_SCC_AUXPATH
              Visual Studio Source Code Control Aux Path.

              Can be set to change the visual studio source code control auxpath property.

       VS_SCC_LOCALPATH
              Visual Studio Source Code Control Local Path.

              Can be set to change the visual studio source code control local path property.

       VS_SCC_PROJECTNAME
              Visual Studio Source Code Control Project.

              Can be set to change the visual studio source code control project name property.

       VS_SCC_PROVIDER
              Visual Studio Source Code Control Provider.

              Can be set to change the visual studio source code control provider property.

       VS_WINRT_EXTENSIONS
              Visual Studio project C++/CX language extensions for Windows Runtime

              Can be set to enable C++/CX language extensions.

       VS_WINRT_REFERENCES
              Visual Studio project Windows Runtime Metadata references

              Adds one or more semicolon-delimited WinRT references to a generated Visual  Studio
              project. For example, "Windows;Windows.UI.Core".

       WIN32_EXECUTABLE
              Build an executable with a WinMain entry point on windows.

              When  this  property  is  set to true the executable when linked on Windows will be
              created with a WinMain() entry point instead of just main().  This makes it  a  GUI
              executable  instead  of  a  console  application.   See the CMAKE_MFC_FLAG variable
              documentation to configure use of MFC for WinMain executables.   This  property  is
              initialized by the value of the variable CMAKE_WIN32_EXECUTABLE if it is set when a
              target is created.

       XCODE_ATTRIBUTE_<an-attribute>
              Set Xcode target attributes directly.

              Tell the Xcode generator to set '<an-attribute>' to a given value in the  generated
              Xcode project.  Ignored on other generators.

PROPERTIES ON TESTS

       ATTACHED_FILES
              Attach a list of files to a dashboard submission.

              Set  this  property  to  a  list of files that will be encoded and submitted to the
              dashboard as an addition to the test result.

       ATTACHED_FILES_ON_FAIL
              Attach a list of files to a dashboard submission if the test fails.

              Same as ATTACHED_FILES, but these files will only be included if the test does  not
              pass.

       COST   Set  this  to a floating point value. Tests in a test set will be run in descending
              order of cost.

              This property describes the cost of a test. You  can  explicitly  set  this  value;
              tests with higher COST values will run first.

       DEPENDS
              Specifies that this test should only be run after the specified list of tests.

              Set this to a list of tests that must finish before this test is run.

       ENVIRONMENT
              Specify environment variables that should be defined for running a test.

              If  set to a list of environment variables and values of the form MYVAR=value those
              environment variables will be defined while running the test.  The  environment  is
              restored to its previous state after the test is done.

       FAIL_REGULAR_EXPRESSION
              If the output matches this regular expression the test will fail.

              If  set,  if the output matches one of specified regular expressions, the test will
              fail.For example: FAIL_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"

       LABELS Specify a list of text labels associated with a test.

              The list is reported in dashboard submissions.

       MEASUREMENT
              Specify a CDASH measurement and value to be reported for a test.

              If set to a name then that name will be reported to CDASH as  a  named  measurement
              with  a  value  of  1.  You  may  also  specify  a  value by setting MEASUREMENT to
              "measurement=value".

       PASS_REGULAR_EXPRESSION
              The output must match this regular expression for the test to pass.

              If set, the test output will be checked against the specified  regular  expressions
              and  at  least one of the regular expressions has to match, otherwise the test will
              fail.

       PROCESSORS
              How many process slots this test requires

              Denotes the number of processors that this test will  require.  This  is  typically
              used  for  MPI  tests,  and  should  be  used  in  conjunction  with the ctest_test
              PARALLEL_LEVEL option.

       REQUIRED_FILES
              List of files required to run the test.

              If set to a list of files, the test will not be run unless all of the files exist.

       RESOURCE_LOCK
              Specify a list of resources that are locked by this test.

              If multiple tests specify the same resource lock, they are guaranteed  not  to  run
              concurrently.

       RUN_SERIAL
              Do not run this test in parallel with any other test.

              Use this option in conjunction with the ctest_test PARALLEL_LEVEL option to specify
              that this test should not be run in parallel with any other tests.

       TIMEOUT
              How many seconds to allow for this test.

              This property if set will limit a test to not take more than the  specified  number
              of  seconds  to  run.  If it exceeds that the test process will be killed and ctest
              will   move   to   the   next   test.   This   setting   takes   precedence    over
              CTEST_TESTING_TIMEOUT.

       WILL_FAIL
              If set to true, this will invert the pass/fail flag of the test.

              This property can be used for tests that are expected to fail and return a non zero
              return code.

       WORKING_DIRECTORY
              The directory from which the test executable will be called.

              If this is not set it is called from the directory the test executable  is  located
              in.

PROPERTIES ON SOURCE FILES

       ABSTRACT
              Is this source file an abstract class.

              A  property  on  a source file that indicates if the source file represents a class
              that is abstract. This only makes sense for languages that  have  a  notion  of  an
              abstract  class  and  it  is  only  used by some tools that wrap classes into other
              languages.

       COMPILE_DEFINITIONS
              Preprocessor definitions for compiling a source file.

              The COMPILE_DEFINITIONS property may  be  set  to  a  semicolon-separated  list  of
              preprocessor  definitions  using  the  syntax  VAR  or  VAR=value.   Function-style
              definitions are not supported.  CMake will automatically escape the value correctly
              for the native build system (note that CMake language syntax may require escapes to
              specify some values).  This property may be set on a per-configuration basis  using
              the  name  COMPILE_DEFINITIONS_<CONFIG>  where  <CONFIG> is an upper-case name (ex.
              "COMPILE_DEFINITIONS_DEBUG").

              CMake will automatically drop some definitions that are not supported by the native
              build  tool.  The VS6 IDE does not support definition values with spaces (but NMake
              does).  Xcode does not support per-configuration definitions on source files.

              Disclaimer: Most native build tools have poor support for escaping certain  values.
              CMake  has  work-arounds for many cases but some values may just not be possible to
              pass correctly.  If a value does not seem to be escaped correctly, do  not  attempt
              to  work-around  the  problem  by  adding  escape  sequences  to  the  value.  Your
              work-around may break in a  future  version  of  CMake  that  has  improved  escape
              support.   Instead consider defining the macro in a (configured) header file.  Then
              report the limitation.  Known limitations include:

                #          - broken almost everywhere
                ;          - broken in VS IDE 7.0 and Borland Makefiles
                ,          - broken in VS IDE
                %          - broken in some cases in NMake
                & |        - broken in some cases on MinGW
                ^ < > \"   - broken in most Make tools on Windows

              CMake does not reject these values outright because they do  work  in  some  cases.
              Use with caution.

       COMPILE_DEFINITIONS_<CONFIG>
              Per-configuration preprocessor definitions on a source file.

              This is the configuration-specific version of COMPILE_DEFINITIONS.  Note that Xcode
              does not support per-configuration source file  flags  so  this  property  will  be
              ignored by the Xcode generator.

       COMPILE_FLAGS
              Additional flags to be added when compiling this source file.

              These  flags  will  be  added  to  the  list of compile flags when this source file
              builds.  Use COMPILE_DEFINITIONS to pass additional preprocessor definitions.

       EXTERNAL_OBJECT
              If set to true then this is an object file.

              If this property is set to true then the source file is really an object  file  and
              should not be compiled.  It will still be linked into the target though.

       Fortran_FORMAT
              Set to FIXED or FREE to indicate the Fortran source layout.

              This  property tells CMake whether a given Fortran source file uses fixed-format or
              free-format.  CMake will pass  the  corresponding  format  flag  to  the  compiler.
              Consider  using  the  target-wide  Fortran_FORMAT property if all source files in a
              target share the same format.

       GENERATED
              Is this source file generated as part of the build process.

              If a source file is generated by the build process CMake will handle it differently
              in  terms  of  dependency checking etc. Otherwise having a non-existent source file
              could create problems.

       HEADER_FILE_ONLY
              Is this source file only a header file.

              A property on a source file that indicates if the source file is a header file with
              no associated implementation. This is set automatically based on the file extension
              and is used by CMake to determine  if  certain  dependency  information  should  be
              computed.

       KEEP_EXTENSION
              Make the output file have the same extension as the source file.

              If this property is set then the file extension of the output file will be the same
              as that of the source file. Normally the output file extension is computed based on
              the language of the source file, for example .cxx will go to a .o extension.

       LABELS Specify a list of text labels associated with a source file.

              This  property  has  meaning  only when the source file is listed in a target whose
              LABELS property is also set.  No other semantics are currently specified.

       LANGUAGE
              What programming language is the file.

              A property that can be set to indicate what programming language  the  source  file
              is.  If  it  is  not  set  the  language is determined based on the file extension.
              Typical values are CXX C etc. Setting this property for a file means this file will
              be compiled. Do not set this for headers or files that should not be compiled.

       LOCATION
              The full path to a source file.

              A  read  only  property  on a SOURCE FILE that contains the full path to the source
              file.

       MACOSX_PACKAGE_LOCATION
              Place a source file inside a Mac OS X bundle, CFBundle, or framework.

              Executable targets with the MACOSX_BUNDLE property  set  are  built  as  Mac  OS  X
              application  bundles on Apple platforms.  Shared library targets with the FRAMEWORK
              property set are built as Mac OS X frameworks on Apple platforms.   Module  library
              targets  with  the  BUNDLE  property  set are built as Mac OS X CFBundle bundles on
              Apple platforms.  Source files listed in the target with this property set will  be
              copied  to  a  directory inside the bundle or framework content folder specified by
              the property value.  For bundles the content folder is "<name>.app/Contents".   For
              frameworks   the  content  folder  is  "<name>.framework/Versions/<version>".   For
              cfbundles the content folder is "<name>.bundle/Contents" (unless the  extension  is
              changed).   See  the  PUBLIC_HEADER, PRIVATE_HEADER, and RESOURCE target properties
              for specifying files meant for Headers, PrivateHeaders, or Resources directories.

       OBJECT_DEPENDS
              Additional files on which a compiled object file depends.

              Specifies a semicolon-separated list of full-paths to files  on  which  any  object
              files  compiled from this source file depend.  An object file will be recompiled if
              any of the named files is newer than it.

              This property need not be used to specify the dependency of  a  source  file  on  a
              generated  header  file  that  it  includes.   Although the property was originally
              introduced for this purpose, it is no longer necessary.  If  the  generated  header
              file  is  created  by  a  custom command in the same target as the source file, the
              automatic dependency scanning  process  will  recognize  the  dependency.   If  the
              generated  header  file  is  created  by another target, an inter-target dependency
              should be created with the add_dependencies command (if one does not already  exist
              due to linking relationships).

       OBJECT_OUTPUTS
              Additional outputs for a Makefile rule.

              Additional  outputs  created  by  compilation  of this source file. If any of these
              outputs is missing the object  will  be  recompiled.  This  is  supported  only  on
              Makefile generators and will be ignored on other generators.

       SYMBOLIC
              Is this just a name for a rule.

              If  SYMBOLIC  (boolean)  is  set to true the build system will be informed that the
              source file is not actually created on disk but instead used as a symbolic name for
              a build rule.

       WRAP_EXCLUDE
              Exclude this source file from any code wrapping techniques.

              Some  packages can wrap source files into alternate languages to provide additional
              functionality. For example, C++ code can be wrapped into Java or Python  etc  using
              SWIG  etc.  If  WRAP_EXCLUDE is set to true (1 etc) that indicates that this source
              file should not be wrapped.

PROPERTIES ON CACHE ENTRIES

       ADVANCED
              True if entry should be hidden by default in GUIs.

              This is a boolean value indicating whether the entry is considered interesting only
              for advanced configuration.  The mark_as_advanced() command modifies this property.

       HELPSTRING
              Help associated with entry in GUIs.

              This string summarizes the purpose of an entry to help users set it through a CMake
              GUI.

       MODIFIED
              Internal management property.  Do not set or get.

              This is an internal cache entry property managed by CMake to track interactive user
              modification of entries.  Ignore it.

       STRINGS
              Enumerate possible STRING entry values for GUI selection.

              For  cache  entries  with type STRING, this enumerates a set of values.  CMake GUIs
              may use this to provide a selection widget instead of a generic string entry field.
              This is for convenience only.  CMake does not enforce that the value matches one of
              those listed.

       TYPE   Widget type for entry in GUIs.

              Cache entry values are always strings, but CMake GUIs present widgets to help users
              set  values.   The  GUIs  use this property as a hint to determine the widget type.
              Valid TYPE values are:

                BOOL          = Boolean ON/OFF value.
                PATH          = Path to a directory.
                FILEPATH      = Path to a file.
                STRING        = Generic string value.
                INTERNAL      = Do not present in GUI at all.
                STATIC        = Value managed by CMake, do not change.
                UNINITIALIZED = Type not yet specified.

              Generally the TYPE of a cache entry should be set by the command which  creates  it
              (set, option, find_library, etc.).

       VALUE  Value of a cache entry.

              This  property  maps  to  the actual value of a cache entry.  Setting this property
              always sets the value without checking, so use with care.
