man cmakevars (1): 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 name of the program that creates archive or static libraries.

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_MAKE_PROGRAM 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 is 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 is 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 is 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_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.

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_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 for make based generators.

This specifies what build type will be built in this tree. Possible values are empty, Debug, Release, RelWithDebInfo and MinSizeRel. This variable is only supported for make based generators. If this variable is supported, then CMake will also provide initial values for the variables with the name CMAKE_C_FLAGS_[Debug|Release|RelWithDebInfo|MinSizeRel]. For example, if CMAKE_BUILD_TYPE is Debug, then CMAKE_C_FLAGS_DEBUG will be added to the CMAKE_C_FLAGS.

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.

This specifies what build types 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.

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_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_PREFIX

Install directory used by install.

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

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 static 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_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_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. 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.

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 file that can change the build rule variables.

If this variable is set, it should to point to a CMakeLists.txt file that will be read in by CMake after all the system settings have been set, but before they have been used. This would allow you to override any variables that need to be changed for some special project.

VARIABLES THAT DESCRIBE THE SYSTEM

APPLE

True if running on Mac OSX.

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

CMAKE_HOST_SYSTEM_NAME

Name of the OS CMake is running on.

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

CMAKE_HOST_WIN32

True on windows systems, including win64.

Set to true when the host system is Windows and on cygwin.

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 OSX 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

OS version CMake is building for.

A numeric version string for the system, on systems that support uname, this variable is set to the output of uname -r. On other systems this is set to major-minor version numbers.

CYGWIN

True for cygwin.

Set to true when using CYGWIN.

MSVC

True when using Microsoft Visual C

Set to true when the compiler is some version of Microsoft Visual C.

MSVC80

True when using Microsoft Visual C 8.0

VARIABLES THAT CONTROL THE BUILD

CMAKE_<CONFIG>_POSTFIX

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_ARCHIVE_OUTPUT_DIRECTORY

Where to put all the ARCHIVE targets when built.

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

CMAKE_BUILD_WITH_INSTALL_RPATH

Use the install path for the RPATH

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 built with the install path for the RPATH and does not need to be relinked when installed.

CMAKE_DEBUG_POSTFIX

See variable CMAKE_<CONFIG>_POSTFIX.

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

CMAKE_EXE_LINKER_FLAGS

Linker flags used to create executables.

Flags used by the linker when creating an executable.

CMAKE_EXE_LINKER_FLAGS_[CMAKE_BUILD_TYPE]

Flag used when linking an executable.

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

CMAKE_Fortran_MODULE_DIRECTORY

Fortran module output directory.

This variable is used to initialize the Fortran_MODULE_DIRECTORY property on all the targets. 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_INSTALL_NAME_DIR

Mac OSX 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 used to add a library search path to a compiler.

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

CMAKE_LINK_DEF_FILE_FLAG

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

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

CMAKE_LINK_LIBRARY_FILE_FLAG

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

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

CMAKE_LINK_LIBRARY_FLAG

Flag used to link a library into an executable.

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

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_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_SKIP_BUILD_RPATH

Do not include RPATHs in the build tree.

CMAKE_USE_RELATIVE_PATHS

Use relative paths (May not work!).

If this is set to TRUE, then the 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.

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

The full path to the compiler for LANG.

This is the command that will be used as the <LANG> compiler. Once set, you can not change this variable.

CMAKE_<LANG>_COMPILER_ABI

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

CMAKE_<LANG>_CREATE_SHARED_LIBRARY

Rule variable to create a shared library.

This is a rule variable that tells CMake how to create a shared library for the language <LANG>.

CMAKE_<LANG>_CREATE_SHARED_MODULE

Rule variable to create a shared module.

This is a rule variable that tells CMake how to create a shared library for the language <LANG>.

CMAKE_<LANG>_CREATE_STATIC_LIBRARY

Rule variable to create a static library.

This is a rule variable that tells CMake how to create a static library for the language <LANG>.

CMAKE_<LANG>_FLAGS_DEBUG

Flags for Debug build type or configuration.

<LANG> flags used when CMAKE_BUILD_TYPE is Debug.

CMAKE_<LANG>_FLAGS_MINSIZEREL

Flags for MinSizeRel build type or configuration.

<LANG> flags used when CMAKE_BUILD_TYPE is MinSizeRel.Short for minimum size release.

Flags for RelWithDebInfo type or configuration.

<LANG> flags used when CMAKE_BUILD_TYPE is RelWithDebInfo. Short for Release With Debug 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.

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>_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 and executable.

Rule variable to link and executable for the given language.

CMAKE_<LANG>_OUTPUT_EXTENSION

Extension for the output of a compile for a single file.

Extensions of source files for the given language.

This is the list of extensions for a given languages 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.

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 file that can change the build rule variables.
