The mpi libraries are not installed in the normal library search path
in Fedora, hence the provides/requires tags use a suffix. This suffix also
allows multiple mpi implementations to provide libmpi.

See https://docs.fedoraproject.org/en-US/packaging-guidelines/MPI/.

If you post your .spec file somewhere, I can take a look.
