| compiler_flags | |
| ----------------- | |
| * The :variable:`CMAKE_<LANG>_COMPILER` variable may now be used to | |
| store "mandatory" compiler flags like the :envvar:`CC` and other environment variables. | |
| * The :variable:`CMAKE_<LANG>_FLAGS_INIT` variable will now be considered during | |
| the compiler indentification check if other sources like :variable:`CMAKE_<LANG>_FLAGS` | |
| or :envvar:`CFLAGS` are not set. |
