| ``CMAKE_REQUIRED_FLAGS`` | |
| String of additional flags to pass to the compiler. The string must be | |
| space-delimited--a :ref:`;-list <CMake Language Lists>` will not work. | |
| The contents of :variable:`CMAKE_<LANG>_FLAGS <CMAKE_<LANG>_FLAGS>` and | |
| its associated configuration-specific variable are automatically added | |
| to the compiler command before the contents of ``CMAKE_REQUIRED_FLAGS``. |
