[MOAB-dev] Disable fortran in moab-5.0.0

[Lorenzo Botti]

Thank you very much Vijay. It worked.
To me this setup is really helpful.

Just a note. The disable fortran option should be taken into account also
on the hdf5 build when configuring moab with download-hdf5. Otherwise that
will fail.

Hope that the new option will be included in future releases.
