While it would be nice to really fix FortranCInterface_VERIFY(), the
cmake macros here are one of the worst things I've seen in a long time
and decided this is just not worth my time.

If you go search for 'Verifying Fortran/C Interface' on exopi, you'll find
that lapack is the only package running this crap. It has no side effects
as far as I can tell, so let's skip it until someone who likes to roll in
cmake finds the time and motivation to track this down.
