enabling OpenMP in gcc needs -fopenmp as far as I know (It implies -pthreads, so it should automatically compile and link against that too: https://gcc.gnu.org/onlinedocs/gcc/C-Dialect-Options.html#C-Dialect-Options).

Plus the IFCpp define for the OpenMP directives, which is ENABLE_OPENMP.

That should do it, as far as I know.
