NAME

       cmakevars - Reference of CMake variables.

VARIABLES THAT PROVIDE INFORMATION

       variables defined by cmake, that give information about the project, and cmake

       CMAKE_AR
              Name of archiving tool for static libraries.

              This specifies the name of the program that creates archive or static libraries.

       CMAKE_ARGC
              Number of command line arguments passed to CMake in script mode.

              When  run in -P script mode, CMake sets this variable to the number of command line arguments. See
              also CMAKE_ARGV0, 1, 2 ...

       CMAKE_ARGV0
              Command line argument passed to CMake in script mode.

              When run in -P script mode, CMake sets this variable to the first command line argument.  It  then
              also  sets  CMAKE_ARGV1,  CMAKE_ARGV2,  ...  and so on, up to the number of command line arguments
              given. See also CMAKE_ARGC.

       CMAKE_BINARY_DIR
              The path to the top level of the build tree.

              This is the full path to the top level of the current CMake build tree. For  an  in-source  build,
              this would be the same as CMAKE_SOURCE_DIR.

       CMAKE_BUILD_TOOL
              Tool used for the actual build process.

              This  variable  is  set  to the program that will be needed to build the output of CMake.   If the
              generator selected was Visual Studio 6, the CMAKE_BUILD_TOOL  will  be  set  to  msdev,  for  Unix
              Makefiles  it  will  be set to make or gmake, and for Visual Studio 7 it set to devenv.  For NMake
              Makefiles the value is nmake. This can be useful for adding special flags and  commands  based  on
              the final build environment.

       CMAKE_CACHEFILE_DIR
              The directory with the CMakeCache.txt file.

              This  is  the full path to the directory that has the CMakeCache.txt file in it.  This is the same
              as CMAKE_BINARY_DIR.

       CMAKE_CACHE_MAJOR_VERSION
              Major version of CMake used to create the CMakeCache.txt file

              This stores the major version of CMake used to write a CMake cache file. It is only different when
              a different version of CMake is run on a previously created cache file.

       CMAKE_CACHE_MINOR_VERSION
              Minor version of CMake used to create the CMakeCache.txt file

              This stores the minor version of CMake used to write a CMake cache file. It is only different when
              a different version of CMake is run on a previously created cache file.

       CMAKE_CACHE_PATCH_VERSION
              Patch version of CMake used to create the CMakeCache.txt file

              This stores the patch version of CMake used to write a CMake cache file. It is only different when
              a different version of CMake is run on a previously created cache file.

       CMAKE_CFG_INTDIR
              Build-time reference to per-configuration output subdirectory.

              For  native  build  systems  supporting  multiple configurations in the build tree (such as Visual
              Studio and Xcode), the value is a reference to a build-time variable specifying the  name  of  the
              per-configuration output subdirectory.  On Makefile generators this evaluates to "." because there
              is only one configuration in a build tree.  Example values:

                $(IntDir)        = Visual Studio 6
                $(OutDir)        = Visual Studio 7, 8, 9
                $(Configuration) = Visual Studio 10
                $(CONFIGURATION) = Xcode
                .                = Make-based tools

              Since these values are evaluated by the native build system, this variable is  suitable  only  for
              use in command lines that will be evaluated at build time.  Example of intended usage:

                add_executable(mytool mytool.c)
                add_custom_command(
                  OUTPUT out.txt
                  COMMAND ${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool
                          ${CMAKE_CURRENT_SOURCE_DIR}/in.txt out.txt
                  DEPENDS mytool in.txt
                  )
                add_custom_target(drive ALL DEPENDS out.txt)

              Note  that  CMAKE_CFG_INTDIR  is  no  longer  necessary  for  this  purpose  but has been left for
              compatibility with existing projects.  Instead add_custom_command() recognizes  executable  target
              names  in  its  COMMAND option, so "${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool" can be
              replaced by just "mytool".

              This variable is read-only.  Setting it  is  undefined  behavior.   In  multi-configuration  build
              systems the value of this variable is passed as the value of preprocessor symbol "CMAKE_INTDIR" to
              the compilation of all source files.

       CMAKE_COMMAND
              The full path to the cmake executable.

              This is the full path to the CMake executable cmake which is useful from custom commands that want
              to use the cmake -E option for portable system commands.  (e.g. /usr/local/bin/cmake

       CMAKE_CROSSCOMPILING
              Is CMake currently cross compiling.

              This  variable will be set to true by CMake if CMake is cross compiling. Specifically if the build
              platform is different from the target platform.

       CMAKE_CTEST_COMMAND
              Full path to ctest command installed with cmake.

              This is the full path to the CTest executable ctest which is useful from custom commands that want
              to use the cmake -E option for portable system commands.

       CMAKE_CURRENT_BINARY_DIR
              The path to the binary directory currently being processed.

              This  the  full  path  to  the  build  directory that is currently being processed by cmake.  Each
              directory added by add_subdirectory will create a binary directory in the build tree, and as it is
              being  processed  this  variable  will  be  set.   For in-source builds this is the current source
              directory being processed.

       CMAKE_CURRENT_LIST_DIR
              Full directory of the listfile currently being processed.

              As CMake processes the listfiles in your project this variable will always be set to the directory
              where  the  listfile which is currently being processed (CMAKE_CURRENT_LIST_FILE) is located.  The
              value has dynamic scope.  When CMake starts processing commands in a  source  file  it  sets  this
              variable  to  the  directory  where this file is located.  When CMake finishes processing commands
              from the file it restores the previous value.  Therefore the value of the variable inside a  macro
              or function is the directory of the file invoking the bottom-most entry on the call stack, not the
              directory of the file containing the macro or function definition.

              See also CMAKE_CURRENT_LIST_FILE.

       CMAKE_CURRENT_LIST_FILE
              Full path to the listfile currently being processed.

              As CMake processes the listfiles in your project this variable will  always  be  set  to  the  one
              currently being processed.  The value has dynamic scope.  When CMake starts processing commands in
              a source file it sets this variable to the location of the file.  When CMake  finishes  processing
              commands from the file it restores the previous value.  Therefore the value of the variable inside
              a macro or function is the file invoking the bottom-most entry on the call  stack,  not  the  file
              containing the macro or function definition.

              See also CMAKE_PARENT_LIST_FILE.

       CMAKE_CURRENT_LIST_LINE
              The line number of the current file being processed.

              This is the line number of the file currently being processed by cmake.

       CMAKE_CURRENT_SOURCE_DIR
              The path to the source directory currently being processed.

              This the full path to the source directory that is currently being processed by cmake.

       CMAKE_DL_LIBS
              Name of library containing dlopen and dlcose.

              The name of the library that has dlopen and dlclose in it, usually -ldl on most UNIX machines.

       CMAKE_EDIT_COMMAND
              Full path to cmake-gui or ccmake.

              This  is  the full path to the CMake executable that can graphically edit the cache.  For example,
              cmake-gui, ccmake, or cmake -i.

       CMAKE_EXECUTABLE_SUFFIX
              The suffix for executables on this platform.

              The suffix to use for the end of an executable filename if any, .exe on Windows.

              CMAKE_EXECUTABLE_SUFFIX_<LANG> overrides this for language <LANG>.

       CMAKE_EXTRA_GENERATOR
              The extra generator used to build the project.

              When  using  the  Eclipse,  CodeBlocks  or  KDevelop   generators,   CMake   generates   Makefiles
              (CMAKE_GENERATOR)  and  additionally  project  files for the respective IDE. This IDE project file
              generator is stored in CMAKE_EXTRA_GENERATOR (e.g. "Eclipse CDT4").

       CMAKE_EXTRA_SHARED_LIBRARY_SUFFIXES
              Additional suffixes for shared libraries.

              Extensions for shared libraries other than that specified by CMAKE_SHARED_LIBRARY_SUFFIX, if  any.
              CMake  uses this to recognize external shared library files during analysis of libraries linked by
              a target.

       CMAKE_GENERATOR
              The generator used to build the project.

              The name of the generator that is being used to generate the build files.  (e.g. "Unix Makefiles",
              "Visual Studio 6", etc.)

       CMAKE_GENERATOR_TOOLSET
              Native build system toolset name specified by user.

              Some  CMake  generators  support a toolset name to be given to the native build system to choose a
              compiler.  If the user specifies a toolset name (e.g. via the cmake -T option) the value  will  be
              available in this variable.

       CMAKE_HOME_DIRECTORY
              Path to top of source tree.

              This is the path to the top level of the source tree.

       CMAKE_IMPORT_LIBRARY_PREFIX
              The prefix for import libraries that you link to.

              The prefix to use for the name of an import library if used on this platform.

              CMAKE_IMPORT_LIBRARY_PREFIX_<LANG> overrides this for language <LANG>.

       CMAKE_IMPORT_LIBRARY_SUFFIX
              The suffix for import libraries that you link to.

              The suffix to use for the end of an import library filename if used on this platform.

              CMAKE_IMPORT_LIBRARY_SUFFIX_<LANG> overrides this for language <LANG>.

       CMAKE_LINK_LIBRARY_SUFFIX
              The suffix for libraries that you link to.

              The suffix to use for the end of a library filename, .lib on Windows.

       CMAKE_MAJOR_VERSION
              The Major version of cmake (i.e. the 2 in 2.X.X)

              This specifies the major version of the CMake executable being run.

       CMAKE_MAKE_PROGRAM
              See CMAKE_BUILD_TOOL.

              This variable is around for backwards compatibility, see CMAKE_BUILD_TOOL.

       CMAKE_MINIMUM_REQUIRED_VERSION
              Version specified to cmake_minimum_required command

              Variable containing the VERSION component specified in the cmake_minimum_required command.

       CMAKE_MINOR_VERSION
              The Minor version of cmake (i.e. the 4 in X.4.X).

              This specifies the minor version of the CMake executable being run.

       CMAKE_PARENT_LIST_FILE
              Full path to the CMake file that included the current one.

              While  processing  a  CMake  file loaded by include() or find_package() this variable contains the
              full path to the file including it.  The top of the include stack is always the CMakeLists.txt for
              the current directory.  See also CMAKE_CURRENT_LIST_FILE.

       CMAKE_PATCH_VERSION
              The patch version of cmake (i.e. the 3 in X.X.3).

              This specifies the patch version of the CMake executable being run.

       CMAKE_PROJECT_NAME
              The name of the current project.

              This specifies name of the current project from the closest inherited PROJECT command.

       CMAKE_RANLIB
              Name of randomizing tool for static libraries.

              This specifies name of the program that randomizes libraries on UNIX, not used on Windows, but may
              be present.

       CMAKE_ROOT
              Install directory for running cmake.

              This is the install root for the running CMake and the Modules directory can be found  here.  This
              is commonly used in this format: ${CMAKE_ROOT}/Modules

       CMAKE_SCRIPT_MODE_FILE
              Full path to the -P script file currently being processed.

              When run in -P script mode, CMake sets this variable to the full path of the script file. When run
              to configure a CMakeLists.txt file, this variable is not set.

       CMAKE_SHARED_LIBRARY_PREFIX
              The prefix for shared libraries that you link to.

              The prefix to use for the name of a shared library, lib on UNIX.

              CMAKE_SHARED_LIBRARY_PREFIX_<LANG> overrides this for language <LANG>.

       CMAKE_SHARED_LIBRARY_SUFFIX
              The suffix for shared libraries that you link to.

              The suffix to use for the end of a shared library filename, .dll on Windows.

              CMAKE_SHARED_LIBRARY_SUFFIX_<LANG> overrides this for language <LANG>.

       CMAKE_SHARED_MODULE_PREFIX
              The prefix for loadable modules that you link to.

              The prefix to use for the name of a loadable module on this platform.

              CMAKE_SHARED_MODULE_PREFIX_<LANG> overrides this for language <LANG>.

       CMAKE_SHARED_MODULE_SUFFIX
              The suffix for shared libraries that you link to.

              The suffix to use for the end of a loadable module filename on this platform

              CMAKE_SHARED_MODULE_SUFFIX_<LANG> overrides this for language <LANG>.

       CMAKE_SIZEOF_VOID_P
              Size of a void pointer.

              This is set to the size of a pointer on the machine, and is determined by a try compile. If  a  64
              bit size is found, then the library search path is modified to look for 64 bit libraries first.

       CMAKE_SKIP_RPATH
              If true, do not add run time path information.

              If  this  is  set  to  TRUE, then the rpath information is not added to compiled executables.  The
              default is to add rpath information if the platform supports it.  This  allows  for  easy  running
              from  the  build  tree.   To  omit  RPATH  in  the  install  step,  but  not  the  build step, use
              CMAKE_SKIP_INSTALL_RPATH instead.

       CMAKE_SOURCE_DIR
              The path to the top level of the source tree.

              This is the full path to the top level of the current CMake source tree. For an  in-source  build,
              this would be the same as CMAKE_BINARY_DIR.

       CMAKE_STANDARD_LIBRARIES
              Libraries linked into every executable and shared library.

              This is the list of libraries that are linked into all executables and libraries.

       CMAKE_STATIC_LIBRARY_PREFIX
              The prefix for static libraries that you link to.

              The prefix to use for the name of a static library, lib on UNIX.

              CMAKE_STATIC_LIBRARY_PREFIX_<LANG> overrides this for language <LANG>.

       CMAKE_STATIC_LIBRARY_SUFFIX
              The suffix for static libraries that you link to.

              The suffix to use for the end of a static library filename, .lib on Windows.

              CMAKE_STATIC_LIBRARY_SUFFIX_<LANG> overrides this for language <LANG>.

       CMAKE_TWEAK_VERSION
              The tweak version of cmake (i.e. the 1 in X.X.X.1).

              This specifies the tweak version of the CMake executable being run.  Releases use tweak < 20000000
              and development versions use the date format CCYYMMDD for the tweak level.

       CMAKE_VERBOSE_MAKEFILE
              Create verbose makefiles if on.

              This variable defaults to false. You can set this variable to true to make CMake  produce  verbose
              makefiles that show each command line as it is used.

       CMAKE_VERSION
              The full version of cmake in major.minor.patch[.tweak[-id]] format.

              This  specifies  the  full version of the CMake executable being run.  This variable is defined by
              versions   2.6.3   and   higher.    See   variables   CMAKE_MAJOR_VERSION,    CMAKE_MINOR_VERSION,
              CMAKE_PATCH_VERSION,  and  CMAKE_TWEAK_VERSION  for  individual  version  components.   The  [-id]
              component appears in non-release versions and may be arbitrary text.

       CMAKE_VS_PLATFORM_TOOLSET
              Visual Studio Platform Toolset name.

              VS 10 and above use MSBuild under the hood and support multiple compiler  toolchains.   CMake  may
              specify a toolset explicitly, such as "v110" for VS 11 or "Windows7.1SDK" for 64-bit support in VS
              10 Express.  CMake provides the name of the chosen toolset in this variable.

       CMAKE_XCODE_PLATFORM_TOOLSET
              Xcode compiler selection.

              Xcode supports selection of a compiler from one of the installed  toolsets.   CMake  provides  the
              name  of the chosen toolset in this variable, if any is explicitly selected (e.g. via the cmake -T
              option).

       PROJECT_BINARY_DIR
              Full path to build directory for project.

              This is the binary directory of the most recent PROJECT command.

       PROJECT_NAME
              Name of the project given to the project command.

              This is the name given to the most recent PROJECT command.

       PROJECT_SOURCE_DIR
              Top level source directory for the current project.

              This is the source directory of the most recent PROJECT command.

       [Project name]_BINARY_DIR
              Top level binary directory for the named project.

              A variable is created with the name used in the PROJECT command, and is the binary  directory  for
              the project.   This can be useful when SUBDIR is used to connect several projects.

       [Project name]_SOURCE_DIR
              Top level source directory for the named project.

              A  variable  is created with the name used in the PROJECT command, and is the source directory for
              the project.   This can be useful when add_subdirectory is used to connect several projects.

VARIABLES THAT CHANGE BEHAVIOR

BUILD_SHARED_LIBS
Global flag to cause add_library to create shared libraries if on.

If present and true, this will cause all libraries to be built shared unless the library was
explicitly added as a static library. This variable is often added to projects as an OPTION so
that each user of a project can decide if they want to build the project using shared or static
libraries.

CMAKE_ABSOLUTE_DESTINATION_FILES
List of files which have been installed using an ABSOLUTE DESTINATION path.

This variable is defined by CMake-generated cmake_install.cmake scripts. It can be used
(read-only) by programs or scripts that source those install scripts. This is used by some CPack
generators (e.g. RPM).

CMAKE_AUTOMOC_RELAXED_MODE
Switch between strict and relaxed automoc mode.

By default, automoc behaves exactly as described in the documentation of the AUTOMOC target
property. When set to TRUE, it accepts more input and tries to find the correct input file for
moc even if it differs from the documented behaviour. In this mode it e.g. also checks whether a
header file is intended to be processed by moc when a "foo.moc" file has been included.

Relaxed mode has to be enabled for KDE4 compatibility.

CMAKE_BACKWARDS_COMPATIBILITY
Version of cmake required to build project

From the point of view of backwards compatibility, this specifies what version of CMake should be
supported. By default this value is the version number of CMake that you are running. You can set
this to an older version of CMake to support deprecated commands of CMake in projects that were
written to use older versions of CMake. This can be set by the user or set at the beginning of a
CMakeLists file.

CMAKE_BUILD_TYPE
Specifies the build type on single-configuration generators.

This statically specifies what build type (configuration) will be built in this build tree.
Possible values are empty, Debug, Release, RelWithDebInfo and MinSizeRel. This variable is only
meaningful to single-configuration generators (such as make and Ninja) i.e. those which choose a
single configuration when CMake runs to generate a build tree as opposed to multi-configuration
generators which offer selection of the build configuration within the generated build
environment. There are many per-config properties and variables (usually following clean
SOME_VAR_<CONFIG> order conventions), such as CMAKE_C_FLAGS_<CONFIG>, specified as uppercase:
CMAKE_C_FLAGS_[DEBUG|RELEASE|RELWITHDEBINFO|MINSIZEREL]. For example, in a build tree configured
to build type Debug, CMake will see to having CMAKE_C_FLAGS_DEBUG settings get added to the
CMAKE_C_FLAGS settings. See also CMAKE_CONFIGURATION_TYPES.

CMAKE_COLOR_MAKEFILE
Enables color output when using the Makefile generator.

When enabled, the generated Makefiles will produce colored output. Default is ON.

CMAKE_CONFIGURATION_TYPES
Specifies the available build types on multi-config generators.

This specifies what build types (configurations) will be available such as Debug, Release,
RelWithDebInfo etc. This has reasonable defaults on most platforms, but can be extended to
provide other build types. See also CMAKE_BUILD_TYPE for details of managing configuration data,
and CMAKE_CFG_INTDIR.

CMAKE_DEBUG_TARGET_PROPERTIES
Enables tracing output for target properties.

This variable can be populated with a list of properties to generate debug output for when
evaluating target properties. Currently it can only be used when evaluating the
INCLUDE_DIRECTORIES, COMPILE_DEFINITIONS and COMPILE_OPTIONS target properties. In that case, it
outputs a backtrace for each entry in the target property. Default is unset.

CMAKE_DISABLE_FIND_PACKAGE_<PackageName>
Variable for disabling find_package() calls.

Every non-REQUIRED find_package() call in a project can be disabled by setting the variable
CMAKE_DISABLE_FIND_PACKAGE_<PackageName> to TRUE. This can be used to build a project without an
optional package, although that package is installed.

This switch should be used during the initial CMake run. Otherwise if the package has already been
found in a previous CMake run, the variables which have been stored in the cache will still be
there. In that case it is recommended to remove the cache variables for this package from the
cache using the cache editor or cmake -U

CMAKE_ERROR_DEPRECATED
Whether to issue deprecation errors for macros and functions.

If TRUE, this can be used by macros and functions to issue fatal errors when deprecated macros or
functions are used. This variable is FALSE by default.

CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
Ask cmake_install.cmake script to error out as soon as a file with absolute INSTALL DESTINATION is
encountered.

The fatal error is emitted before the installation of the offending file takes place. This
variable is used by CMake-generated cmake_install.cmake scripts. If one sets this variable to ON
while running the script, it may get fatal error messages from the script.

CMAKE_FIND_LIBRARY_PREFIXES
Prefixes to prepend when looking for libraries.

This specifies what prefixes to add to library names when the find_library command looks for
libraries. On UNIX systems this is typically lib, meaning that when trying to find the foo library
it will look for libfoo.

CMAKE_FIND_LIBRARY_SUFFIXES
Suffixes to append when looking for libraries.

This specifies what suffixes to add to library names when the find_library command looks for
libraries. On Windows systems this is typically .lib and .dll, meaning that when trying to find
the foo library it will look for foo.dll etc.

CMAKE_FIND_PACKAGE_WARN_NO_MODULE
Tell find_package to warn if called without an explicit mode.

If find_package is called without an explicit mode option (MODULE, CONFIG or NO_MODULE) and no
Find<pkg>.cmake module is in CMAKE_MODULE_PATH then CMake implicitly assumes that the caller
intends to search for a package configuration file. If no package configuration file is found
then the wording of the failure message must account for both the case that the package is really
missing and the case that the project has a bug and failed to provide the intended Find module.
If instead the caller specifies an explicit mode option then the failure message can be more
specific.

Set CMAKE_FIND_PACKAGE_WARN_NO_MODULE to TRUE to tell find_package to warn when it implicitly
assumes Config mode. This helps developers enforce use of an explicit mode in all calls to
find_package within a project.

CMAKE_IGNORE_PATH
Path to be ignored by FIND_XXX() commands.

Specifies directories to be ignored by searches in FIND_XXX() commands. This is useful in
cross-compiled environments where some system directories contain incompatible but possibly
linkable libraries. For example, on cross-compiled cluster environments, this allows a user to
ignore directories containing libraries meant for the front-end machine that modules like FindX11
(and others) would normally search. By default this is empty; it is intended to be set by the
project. Note that CMAKE_IGNORE_PATH takes a list of directory names, NOT a list of prefixes. If
you want to ignore paths under prefixes (bin, include, lib, etc.), you'll need to specify them
explicitly. See also CMAKE_PREFIX_PATH, CMAKE_LIBRARY_PATH, CMAKE_INCLUDE_PATH,
CMAKE_PROGRAM_PATH.

CMAKE_INCLUDE_PATH
Path used for searching by FIND_FILE() and FIND_PATH().

Specifies a path which will be used both by FIND_FILE() and FIND_PATH(). Both commands will check
each of the contained directories for the existence of the file which is currently searched. By
default it is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_INCLUDE_PATH,
CMAKE_PREFIX_PATH.

CMAKE_INSTALL_DEFAULT_COMPONENT_NAME
Default component used in install() commands.

If an install() command is used without the COMPONENT argument, these files will be grouped into a
default component. The name of this default install component will be taken from this variable.
It defaults to "Unspecified".

CMAKE_INSTALL_PREFIX
Install directory used by install.

If "make install" is invoked or INSTALL is built, this directory is prepended onto all install
directories. This variable defaults to /usr/local on UNIX and c:/Program Files on Windows.

On UNIX one can use the DESTDIR mechanism in order to relocate the whole installation. DESTDIR
means DESTination DIRectory. It is commonly used by makefile users in order to install software at
non-default location. It is usually invoked like this:

make DESTDIR=/home/john install

which will install the concerned software using the installation prefix, e.g. "/usr/local"
prepended with the DESTDIR value which finally gives "/home/john/usr/local".

WARNING: DESTDIR may not be used on Windows because installation prefix usually contains a drive
letter like in "C:/Program Files" which cannot be prepended with some other prefix.

The installation prefix is also added to CMAKE_SYSTEM_PREFIX_PATH so that find_package,
find_program, find_library, find_path, and find_file will search the prefix for other software.

CMAKE_LIBRARY_PATH
Path used for searching by FIND_LIBRARY().

Specifies a path which will be used by FIND_LIBRARY(). FIND_LIBRARY() will check each of the
contained directories for the existence of the library which is currently searched. By default it
is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_LIBRARY_PATH,
CMAKE_PREFIX_PATH.

CMAKE_MFC_FLAG
Tell cmake to use MFC for an executable or dll.

This can be set in a CMakeLists.txt file and will enable MFC in the application. It should be set
to 1 for the static MFC library, and 2 for the shared MFC library. This is used in Visual Studio
6 and 7 project files. The CMakeSetup dialog used MFC and the CMakeLists.txt looks like this:

add_definitions(-D_AFXDLL)
set(CMAKE_MFC_FLAG 2)
add_executable(CMakeSetup WIN32 ${SRCS})

CMAKE_MODULE_PATH
List of directories to search for CMake modules.

Commands like include() and find_package() search for files in directories listed by this variable
before checking the default modules that come with CMake.

CMAKE_NOT_USING_CONFIG_FLAGS
Skip _BUILD_TYPE flags if true.

This is an internal flag used by the generators in CMake to tell CMake to skip the _BUILD_TYPE
flags.

CMAKE_POLICY_DEFAULT_CMP<NNNN>
Default for CMake Policy CMP<NNNN> when it is otherwise left unset.

Commands cmake_minimum_required(VERSION) and cmake_policy(VERSION) by default leave policies
introduced after the given version unset. Set CMAKE_POLICY_DEFAULT_CMP<NNNN> to OLD or NEW to
specify the default for policy CMP<NNNN>, where <NNNN> is the policy number.

This variable should not be set by a project in CMake code; use cmake_policy(SET) instead. Users
running CMake may set this variable in the cache (e.g. -DCMAKE_POLICY_DEFAULT_CMP<NNNN>=<OLD|NEW>)
to set a policy not otherwise set by the project. Set to OLD to quiet a policy warning while
using old behavior or to NEW to try building the project with new behavior.

CMAKE_PREFIX_PATH
Path used for searching by FIND_XXX(), with appropriate suffixes added.

Specifies a path which will be used by the FIND_XXX() commands. It contains the "base"
directories, the FIND_XXX() commands append appropriate subdirectories to the base directories. So
FIND_PROGRAM() adds /bin to each of the directories in the path, FIND_LIBRARY() appends /lib to
each of the directories, and FIND_PATH() and FIND_FILE() append /include . By default it is empty,
it is intended to be set by the project. See also CMAKE_SYSTEM_PREFIX_PATH, CMAKE_INCLUDE_PATH,
CMAKE_LIBRARY_PATH, CMAKE_PROGRAM_PATH.

CMAKE_PROGRAM_PATH
Path used for searching by FIND_PROGRAM().

Specifies a path which will be used by FIND_PROGRAM(). FIND_PROGRAM() will check each of the
contained directories for the existence of the program which is currently searched. By default it
is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_PROGRAM_PATH,
CMAKE_PREFIX_PATH.

CMAKE_SKIP_INSTALL_ALL_DEPENDENCY
Don't make the install target depend on the all target.

By default, the "install" target depends on the "all" target. This has the effect, that when
"make install" is invoked or INSTALL is built, first the "all" target is built, then the
installation starts. If CMAKE_SKIP_INSTALL_ALL_DEPENDENCY is set to TRUE, this dependency is not
created, so the installation process will start immediately, independent from whether the project
has been completely built or not.

CMAKE_SYSTEM_IGNORE_PATH
Path to be ignored by FIND_XXX() commands.

Specifies directories to be ignored by searches in FIND_XXX() commands. This is useful in
cross-compiled environments where some system directories contain incompatible but possibly
linkable libraries. For example, on cross-compiled cluster environments, this allows a user to
ignore directories containing libraries meant for the front-end machine that modules like FindX11
(and others) would normally search. By default this contains a list of directories containing
incompatible binaries for the host system. See also CMAKE_SYSTEM_PREFIX_PATH,
CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_SYSTEM_INCLUDE_PATH, and CMAKE_SYSTEM_PROGRAM_PATH.

CMAKE_SYSTEM_INCLUDE_PATH
Path used for searching by FIND_FILE() and FIND_PATH().

Specifies a path which will be used both by FIND_FILE() and FIND_PATH(). Both commands will check
each of the contained directories for the existence of the file which is currently searched. By
default it contains the standard directories for the current system. It is NOT intended to be
modified by the project, use CMAKE_INCLUDE_PATH for this. See also CMAKE_SYSTEM_PREFIX_PATH.

CMAKE_SYSTEM_LIBRARY_PATH
Path used for searching by FIND_LIBRARY().

Specifies a path which will be used by FIND_LIBRARY(). FIND_LIBRARY() will check each of the
contained directories for the existence of the library which is currently searched. By default it
contains the standard directories for the current system. It is NOT intended to be modified by the
project, use CMAKE_LIBRARY_PATH for this. See also CMAKE_SYSTEM_PREFIX_PATH.

CMAKE_SYSTEM_PREFIX_PATH
Path used for searching by FIND_XXX(), with appropriate suffixes added.

Specifies a path which will be used by the FIND_XXX() commands. It contains the "base"
directories, the FIND_XXX() commands append appropriate subdirectories to the base directories. So
FIND_PROGRAM() adds /bin to each of the directories in the path, FIND_LIBRARY() appends /lib to
each of the directories, and FIND_PATH() and FIND_FILE() append /include . By default this
contains the standard directories for the current system and the CMAKE_INSTALL_PREFIX. It is NOT
intended to be modified by the project, use CMAKE_PREFIX_PATH for this. See also
CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_SYSTEM_PROGRAM_PATH, and
CMAKE_SYSTEM_IGNORE_PATH.

CMAKE_SYSTEM_PROGRAM_PATH
Path used for searching by FIND_PROGRAM().

Specifies a path which will be used by FIND_PROGRAM(). FIND_PROGRAM() will check each of the
contained directories for the existence of the program which is currently searched. By default it
contains the standard directories for the current system. It is NOT intended to be modified by the
project, use CMAKE_PROGRAM_PATH for this. See also CMAKE_SYSTEM_PREFIX_PATH.

CMAKE_USER_MAKE_RULES_OVERRIDE
Specify a CMake file that overrides platform information.

CMake loads the specified file while enabling support for each language from either the project()
or enable_language() commands. It is loaded after CMake's builtin compiler and platform
information modules have been loaded but before the information is used. The file may set
platform information variables to override CMake's defaults.

This feature is intended for use only in overriding information variables that must be set before
CMake builds its first test project to check that the compiler for a language works. It should
not be used to load a file in cases that a normal include() will work. Use it only as a last
resort for behavior that cannot be achieved any other way. For example, one may set
CMAKE_C_FLAGS_INIT to change the default value used to initialize CMAKE_C_FLAGS before it is
cached. The override file should NOT be used to set anything that could be set after languages
are enabled, such as variables like CMAKE_RUNTIME_OUTPUT_DIRECTORY that affect the placement of
binaries. Information set in the file will be used for try_compile and try_run builds too.

CMAKE_WARN_DEPRECATED
Whether to issue deprecation warnings for macros and functions.

If TRUE, this can be used by macros and functions to issue deprecation warnings. This variable is
FALSE by default.

CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
Ask cmake_install.cmake script to warn each time a file with absolute INSTALL DESTINATION is
encountered.

This variable is used by CMake-generated cmake_install.cmake scripts. If one sets this variable to
ON while running the script, it may get warning messages from the script.

The same as CMAKE_SYSTEM_NAME but for the host system instead of the target system when cross
compiling.

CMAKE_HOST_SYSTEM_PROCESSOR
The name of the CPU CMake is running on.

The same as CMAKE_SYSTEM_PROCESSOR but for the host system instead of the target system when cross

Target architecture library directory name, if detected.

This is the value of CMAKE_<lang>_LIBRARY_ARCHITECTURE as detected for one of the enabled
languages.

CMAKE_LIBRARY_ARCHITECTURE_REGEX
Regex matching possible target architecture library directory names.

This is used to detect CMAKE_<lang>_LIBRARY_ARCHITECTURE from the implicit linker search path by
matching the <arch> name.

CMAKE_OBJECT_PATH_MAX
Maximum object file full-path length allowed by native build tools.

CMake computes for every source file an object file name that is unique to the source file and
deterministic with respect to the full path to the source file. This allows multiple source files
in a target to share the same name if they lie in different directories without rebuilding when
one is added or removed. However, it can produce long full paths in a few cases, so CMake
shortens the path using a hashing scheme when the full path to an object file exceeds a limit.
CMake has a built-in limit for each platform that is sufficient for common tools, but some native
tools may have a lower limit. This variable may be set to specify the limit explicitly. The
value must be an integer no less than 128.

CMAKE_SYSTEM
Name of system cmake is compiling for.

This variable is the composite of CMAKE_SYSTEM_NAME and CMAKE_SYSTEM_VERSION, like this
${CMAKE_SYSTEM_NAME}-${CMAKE_SYSTEM_VERSION}. If CMAKE_SYSTEM_VERSION is not set, then
CMAKE_SYSTEM is the same as CMAKE_SYSTEM_NAME.

CMAKE_SYSTEM_NAME
Name of the OS CMake is building for.

This is the name of the operating system on which CMake is targeting. On systems that have the
uname command, this variable is set to the output of uname -s. Linux, Windows, and Darwin for
Mac OS X are the values found on the big three operating systems.

CMAKE_SYSTEM_PROCESSOR
The name of the CPU CMake is building for.

On systems that support uname, this variable is set to the output of uname -p, on windows it is
set to the value of the environment variable PROCESSOR_ARCHITECTURE

CMAKE_SYSTEM_VERSION

Default filename postfix for libraries under configuration <CONFIG>.

When a non-executable target is created its <CONFIG>_POSTFIX target property is initialized with
the value of this variable if it is set.

CMAKE_<LANG>_VISIBILITY_PRESET
Default value for <LANG>_VISIBILITY_PRESET of targets.

This variable is used to initialize the <LANG>_VISIBILITY_PRESET property on all the targets. See
that target property for additional information.

This variable is used to initialize the Fortran_MODULE_DIRECTORY property on all the targets. See
that target property for additional information.

CMAKE_GNUtoMS
Convert GNU import libraries (.dll.a) to MS format (.lib).

This variable is used to initialize the GNUtoMS property on targets when they are created. See
that target property for additional information.

CMAKE_INCLUDE_CURRENT_DIR
Automatically add the current source- and build directories to the include path.

If this variable is enabled, CMake automatically adds in each directory
${CMAKE_CURRENT_SOURCE_DIR} and ${CMAKE_CURRENT_BINARY_DIR} to the include path for this
directory. These additional include directories do not propagate down to subdirectories. This is
useful mainly for out-of-source builds, where files generated into the build tree are included by
files located in the source tree.

By default CMAKE_INCLUDE_CURRENT_DIR is OFF.

CMAKE_INCLUDE_CURRENT_DIR_IN_INTERFACE
Automatically add the current source- and build directories to the INTERFACE_INCLUDE_DIRECTORIES.

If this variable is enabled, CMake automatically adds for each shared library target, static
library target, module target and executable target, ${CMAKE_CURRENT_SOURCE_DIR} and
${CMAKE_CURRENT_BINARY_DIR} to the INTERFACE_INCLUDE_DIRECTORIES.By default
CMAKE_INCLUDE_CURRENT_DIR_IN_INTERFACE is OFF.

CMAKE_INSTALL_NAME_DIR
Mac OS X directory name for installed targets.

CMAKE_INSTALL_NAME_DIR is used to initialize the INSTALL_NAME_DIR property on all targets. See
that target property for more information.

CMAKE_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 is used to initialize the target property INSTALL_RPATH for all targets.

CMAKE_INSTALL_RPATH_USE_LINK_PATH
Add paths to linker search and installed rpath.

CMAKE_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 is used to initialize the
target property INSTALL_RPATH_USE_LINK_PATH for all targets.

CMAKE_LIBRARY_OUTPUT_DIRECTORY
Where to put all the LIBRARY targets when built.

This variable is used to initialize the LIBRARY_OUTPUT_DIRECTORY property on all the targets. See
that target property for additional information.

CMAKE_LIBRARY_PATH_FLAG
The flag to be used to add a library search path to a compiler.

The flag will be used to specify a library directory to the compiler. On most compilers this is
"-L".

CMAKE_LINK_DEF_FILE_FLAG
Linker flag to be used to specify a .def file for dll creation.

The flag will be used to add a .def file when creating a dll on Windows; this is only defined on
Windows.

CMAKE_LINK_DEPENDS_NO_SHARED
Whether to skip link dependencies on shared library files.

This variable initializes the LINK_DEPENDS_NO_SHARED property on targets when they are created.
See that target property for additional information.

CMAKE_LINK_INTERFACE_LIBRARIES
Default value for LINK_INTERFACE_LIBRARIES of targets.

This variable is used to initialize the LINK_INTERFACE_LIBRARIES property on all the targets. See
that target property for additional information.

CMAKE_LINK_LIBRARY_FILE_FLAG
Flag to be used to link a library specified by a path to its file.

The flag will be used before a library file path is given to the linker. This is needed only on
very few platforms.

CMAKE_LINK_LIBRARY_FLAG
Flag to be used to link a library into an executable.

The flag will be used to specify a library to link to an executable. On most compilers this is
"-l".

CMAKE_MACOSX_BUNDLE
Default value for MACOSX_BUNDLE of targets.

This variable is used to initialize the MACOSX_BUNDLE property on all the targets. See that
target property for additional information.

CMAKE_MODULE_LINKER_FLAGS
Linker flags to be used to create modules.

These flags will be used by the linker when creating a module.

CMAKE_MODULE_LINKER_FLAGS_<CONFIG>
Flags to be used when linking a module.

Same as CMAKE_C_FLAGS_* but used by the linker when creating modules.

CMAKE_NO_BUILTIN_CHRPATH
Do not use the builtin ELF editor to fix RPATHs on installation.

When an ELF binary needs to have a different RPATH after installation than it does in the build
tree, CMake uses a builtin editor to change the RPATH in the installed copy. If this variable is
set to true then CMake will relink the binary before installation instead of using its builtin
editor.

CMAKE_PDB_OUTPUT_DIRECTORY
Where to put all the MS debug symbol files from linker.

This variable is used to initialize the PDB_OUTPUT_DIRECTORY property on all the targets. See
that target property for additional information.

CMAKE_POSITION_INDEPENDENT_CODE
Default value for POSITION_INDEPENDENT_CODE of targets.

This variable is used to initialize the POSITION_INDEPENDENT_CODE property on all the targets.
See that target property for additional information.

CMAKE_RUNTIME_OUTPUT_DIRECTORY
Where to put all the RUNTIME targets when built.

This variable is used to initialize the RUNTIME_OUTPUT_DIRECTORY property on all the targets. See
that target property for additional information.

CMAKE_SHARED_LINKER_FLAGS
Linker flags to be used to create shared libraries.

These flags will be used by the linker when creating a shared library.

CMAKE_SHARED_LINKER_FLAGS_<CONFIG>
Flags to be used when linking a shared library.

Same as CMAKE_C_FLAGS_* but used by the linker when creating shared libraries.

CMAKE_SKIP_BUILD_RPATH
Do not include RPATHs in the build tree.

CMAKE_SKIP_INSTALL_RPATH
Do not include RPATHs in the install tree.

Normally CMake uses the build tree for the RPATH when building executables etc on systems that use
RPATH. When the software is installed the executables etc are relinked by CMake to have the
install RPATH. If this variable is set to true then the software is always installed without
RPATH, even if RPATH is enabled when building. This can be useful for example to allow running
tests from the build directory with RPATH enabled before the installation step. To omit RPATH in
both the build and install steps, use CMAKE_SKIP_RPATH instead.

CMAKE_STATIC_LINKER_FLAGS
Linker flags to be used to create static libraries.

These flags will be used by the linker when creating a static library.

CMAKE_STATIC_LINKER_FLAGS_<CONFIG>
Flags to be used when linking a static library.

Same as CMAKE_C_FLAGS_* but used by the linker when creating static libraries.

CMAKE_TRY_COMPILE_CONFIGURATION
Build configuration used for try_compile and try_run projects.

Projects built by try_compile and try_run are built synchronously during the CMake configuration
step. Therefore a specific build configuration must be chosen even if the generated build system
supports multiple configurations.

CMAKE_USE_RELATIVE_PATHS
Use relative paths (May not work!).

If this is set to TRUE, then CMake will use relative paths between the source and binary tree.
This option does not work for more complicated projects, and relative paths are used when
possible. In general, it is not possible to move CMake generated makefiles to a different
location regardless of the value of this variable.

CMAKE_VISIBILITY_INLINES_HIDDEN
Default value for VISIBILITY_INLINES_HIDDEN of targets.

This variable is used to initialize the VISIBILITY_INLINES_HIDDEN property on all the targets.
See that target property for additional information.

CMAKE_WIN32_EXECUTABLE
Default value for WIN32_EXECUTABLE of targets.

This variable is used to initialize the WIN32_EXECUTABLE property on all the targets. See that
target property for additional information.

EXECUTABLE_OUTPUT_PATH
Old executable location variable.

The target property RUNTIME_OUTPUT_DIRECTORY supercedes this variable for a target if it is set.
Executable targets are otherwise placed in this directory.

LIBRARY_OUTPUT_PATH
Old library location variable.

The target properties ARCHIVE_OUTPUT_DIRECTORY, LIBRARY_OUTPUT_DIRECTORY, and
RUNTIME_OUTPUT_DIRECTORY supercede this variable for a target if they are set. Library targets
are otherwise placed in this directory.

VARIABLES FOR LANGUAGES

       CMAKE_<LANG>_ARCHIVE_APPEND
              Rule variable to append to a static archive.

              This is a rule variable that tells CMake how to append to a static archive.  It is used  in  place
              of  CMAKE_<LANG>_CREATE_STATIC_LIBRARY  on some platforms in order to support large object counts.
              See also CMAKE_<LANG>_ARCHIVE_CREATE and CMAKE_<LANG>_ARCHIVE_FINISH.

       CMAKE_<LANG>_ARCHIVE_CREATE
              Rule variable to create a new static archive.

              This is a rule variable that tells CMake how to create a static archive.  It is used in  place  of
              CMAKE_<LANG>_CREATE_STATIC_LIBRARY on some platforms in order to support large object counts.  See
              also CMAKE_<LANG>_ARCHIVE_APPEND and CMAKE_<LANG>_ARCHIVE_FINISH.

       CMAKE_<LANG>_ARCHIVE_FINISH
              Rule variable to finish an existing static archive.

              This is a rule variable that tells CMake how to finish a static archive.  It is used in  place  of
              CMAKE_<LANG>_CREATE_STATIC_LIBRARY on some platforms in order to support large object counts.  See
              also CMAKE_<LANG>_ARCHIVE_CREATE and CMAKE_<LANG>_ARCHIVE_APPEND.

       CMAKE_<LANG>_COMPILER

              defined for all compilers or languages.

       CMAKE_<LANG>_COMPILE_OBJECT
              Rule variable to compile a single object file.

              This is a rule variable that tells CMake how to compile a single  object  file  for  the  language

              Information.

       CMAKE_<LANG>_IGNORE_EXTENSIONS
              File extensions that should be ignored by the build.

              This is a list of file extensions that may be part of a project for a given language but  are  not
              compiled.

       CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES
              Directories implicitly searched by the compiler for header files.

              CMake does not explicitly specify these directories on compiler command lines for language <LANG>.
              This prevents system include directories from being treated as user include  directories  on  some
              compilers.

       CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES
              Implicit linker search path detected for language <LANG>.

              Compilers  typically  pass  directories  containing language runtime libraries and default library
              search paths when they invoke a linker.  These paths are implicit linker  search  directories  for
              the  compiler's  language.   CMake  automatically  detects these directories for each language and
              reports the results in this variable.

              When a library in one of these directories is given by full path to target_link_libraries()  CMake
              will  generate  the  -l<name>  form  on  link  lines  to  ensure  the linker searches its implicit
              directories for the library.   Note  that  some  toolchains  read  implicit  directories  from  an
              environment  variable  such as LIBRARY_PATH so keep its value consistent when operating in a given
              build tree.

       CMAKE_<LANG>_IMPLICIT_LINK_FRAMEWORK_DIRECTORIES
              Implicit linker framework search path detected for language <LANG>.

              These paths are implicit linker framework search directories for the compiler's  language.   CMake
              automatically  detects  these  directories  for  each  language  and  reports  the results in this
              variable.

       CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
              Implicit link libraries and flags detected for language <LANG>.

              Compilers typically pass language runtime library names and other flags when they invoke a linker.
              These  flags  are  implicit link options for the compiler's language.  CMake automatically detects
              these libraries and flags for each language and reports the results in this variable.

       CMAKE_<LANG>_LIBRARY_ARCHITECTURE
              Target architecture library directory name detected for <lang>.

              If the <lang> compiler passes  to  the  linker  an  architecture-specific  system  library  search
              directory  such  as  <prefix>/lib/<arch>  this variable contains the <arch> name if/as detected by
              CMake.

       CMAKE_<LANG>_LINKER_PREFERENCE
              Preference value for linker language selection.

              The "linker language" for executable, shared library, and module targets  is  the  language  whose
              compiler  will  invoke  the  linker.   The  LINKER_LANGUAGE  target  property  sets  the  language
              explicitly.  Otherwise, the linker language is that whose linker preference value is highest among
              languages      compiled      and     linked     into     the     target.      See     also     the
              CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES variable.

       CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES
              True if CMAKE_<LANG>_LINKER_PREFERENCE propagates across targets.

              This is used when CMake selects a linker language for a target.  Languages compiled directly  into
              the  target are always considered.  A language compiled into static libraries linked by the target
              is considered if this variable is true.

       CMAKE_<LANG>_LINK_EXECUTABLE
              Rule variable to link an executable.

              Rule variable to link an executable for the given language.

       CMAKE_<LANG>_OUTPUT_EXTENSION
              Extension for the output of a compile for a single file.

              This is the extension for an object file for the given <LANG>. For example .obj for C on Windows.

       CMAKE_<LANG>_PLATFORM_ID
              An internal variable subject to change.

              This is used in determining the platform and is subject to change.

       CMAKE_<LANG>_SIZEOF_DATA_PTR
              Size of pointer-to-data types for language <LANG>.

              This holds the size (in bytes) of pointer-to-data types in the target platform ABI.  It is defined
              for languages C and CXX (C++).

       CMAKE_<LANG>_SOURCE_FILE_EXTENSIONS
              Extensions of source files for the given language.

              This is the list of extensions for a given language's source files.

       CMAKE_COMPILER_IS_GNU<LANG>
              True if the compiler is GNU.

              If the selected <LANG> compiler is the GNU compiler then this is TRUE, if not it is FALSE.  Unlike
              the other per-language variables, this uses the GNU syntax for identifying  languages  instead  of
              the CMake syntax. Recognized values of the <LANG> suffix are:

                CC = C compiler
                CXX = C++ compiler
                G77 = Fortran compiler

       CMAKE_Fortran_MODDIR_DEFAULT
              Fortran default module output directory.

              Most  Fortran compilers write .mod files to the current working directory.  For those that do not,
              this is set to "." and used when the Fortran_MODULE_DIRECTORY target property is not set.

       CMAKE_Fortran_MODDIR_FLAG
              Fortran flag for module output directory.

              This stores the flag needed to pass the value of the Fortran_MODULE_DIRECTORY target  property  to
              the compiler.

       CMAKE_Fortran_MODOUT_FLAG
              Fortran flag to enable module output.

              Most  Fortran  compilers write .mod files out by default.  For others, this stores the flag needed
              to enable module output.

       CMAKE_INTERNAL_PLATFORM_ABI
              An internal variable subject to change.

              This is used in determining the compiler ABI and is subject to change.

       CMAKE_USER_MAKE_RULES_OVERRIDE_<LANG>
              Specify a CMake file that overrides platform information for <LANG>.

              This is a language-specific version of CMAKE_USER_MAKE_RULES_OVERRIDE loaded  only  when  enabling
              language <LANG>.
