Comment (by hinder):

 A related issue: the following optionlists in simfactory set
 HDF5_ENABLE_FORTRAN and HDF5_ENABLE_CXX to no:  debian-*, fionn, raspbian,
 ubuntu.  It seems that this makes the simfactory optionlists inconsistent,
 and reflects the personal needs of the users who created those
 optionlists.  If we decide that the HDF5 thorn by default provides the
 Fortran and C++ bindings, then I would like the simfactory configurations
 of the machines to reflect that.  This will have the side-effect of
 requiring HDF5 to be built by Cactus on those machines.  Ideally, a user
 would be able to override such variables in their defs.local.ini file, but
 I don't know how to do that in simfactory.  It would be good to have an
 option "cactusoptions = " which could be set to options to add to the
 optionlist.

 I am thinking of new users who try to use the toolkit with codes that
 require Fortran bindings, and get mysterious build failures on laptops or
 workstations running debian or ubuntu because the default optionlists in
 simfactory for those operating systems are different to all others. I
 think it would be better for Cactus to just build the required HDF5 in
 that case.
