[Paraview] Building ParaView v5.1.2 on Linux from source with support for GPU and SWR.

Hi Frank,

 These should not need to be part of the resulting install and can be left
out of the final packaging.  The build/install tree is a staging area that
only gets selectively pruned from for the final packaging.

3.     Building Mesa v12.0.3 works like a charm. However, the libOSMesa

This should have been fixed a while ago.  I'll try to reproduce it and make
sure the packaging is correct.

That certainly should not be the case.  Do you get the same SWR debugging
messages on both showing:

SWR create screen!
This processor supports AVX2.

If those messages are missing then you're not rendering with OpenSWR
(cernotly not the desired result).  Are youy running pverver as an MPI
job?  If so, how many processes per node vs CPU cores per node?
