FFLAGS

This is a CMake Environment Variable. Its initial value is taken from the calling process environment.

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 CMAKE_Fortran_FLAGS. For any configuration run (including the first), the environment variable will be ignored if the CMAKE_Fortran_FLAGS variable is defined.
