| FFLAGS | |
| ------ | |
| Default compilation flags to be used when compiling ``Fortran`` files. Will only | |
| be used by CMake on the first configuration to determine ``Fortran`` default | |
| compilation flags, after which the value for ``FFLAGS`` is stored in the cache | |
| as :variable:`CMAKE_Fortran_FLAGS <CMAKE_<LANG>_FLAGS>`. For any configuration | |
| run (including the first), the environment variable will be ignored if | |
| the :variable:`CMAKE_Fortran_FLAGS <CMAKE_<LANG>_FLAGS>` variable is defined. |
