When building ParaView binaries on system with Fortran compiler present
and ADIOS enabled, ParaView failed to find ADIOS correctly. The issue
was that though superbuild had disabled Fortran (hence MPI was built
without Fortran) ADIOS tried to find MPI's Fortran components and hence
failed.

In general, since we have an option in superbuild to enable/disable
fortran support, it seems reasonable to have the option affect how
ParaView enables/disables its Fortran components.
