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 :command:`include` will work. Use +it only as a last resort for behavior that cannot be achieved any +other way. For example, one may set the +:variable:`CMAKE_C_FLAGS_INIT <CMAKE_<LANG>_FLAGS_INIT>` variable +to change the default value used to initialize the +:variable:`CMAKE_C_FLAGS <CMAKE_<LANG>_FLAGS>` variable +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 +:variable:`CMAKE_RUNTIME_OUTPUT_DIRECTORY` that affect the placement of +binaries. Information set in the file will be used for :command:`try_compile` +and :command:`try_run` builds too. |
