Paraview Master: new build standard use of `PARAVIEW_USE_MPI`

I don’t quite ketch the comment in latest master commit regarding the new “build” standard:

  • ParaView’s flags forcefully disable some modules. For example, ParaView
    can no longer be built with PARAVIEW_USE_MPI and still build some
    MPI-releated modules.

Could you please elaborate on this?

If PARAVIEW_USE_MPI is off, ParaView will not use MPI at all. If it is on, it will turn on important MPI-related modules. Are you seeing errors when building with MPI enabled (I’m working through buildbot errors, so there may be some latent issues). See for this work.
