In order to compile in OpenMP mode you only need to set PARALLEL_MODE := OMP in config.mk.

For MPI you need to set this variable to MPI (as you did) but also change the compiler to the desired MPI wrapper, e.g. mpic++.

For usage on Windows we recommend the WSL instead of (frequently problematic) Cygwin.
