[Paraview] Superbuild: Passing VTK parameter?

[Utkarsh Ayachit]

Rick,

The ParaViewSuperbuild currently builds a newer version of Mesa which
doesn't allow building with onscreen and offscreen together
(http://paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D), so you're
stuck with two separate builds. Using older-mesa may not work either
since, if I am not mistaken, VTK has some logic after modularization
that'd make using X and OSMesa in the same build difficult, if not
impossible.

I'm relatively new to building ParaView, but in the past, I'm told that we did not use the OSmesa build, we used to build Mesa with VTK_USE_OFFSCREEN=on which apparently achieved the same thing.     I have done the OSmesa build and it does exactly what I want, but it's also forcing me to do two builds - an OSMesa build for the compute node that doesn't have an Xwindow server, and a Mesa build for remote X display from the login node.   I was really looking to see if I could get by with just one build as we've apparently done in the past.
