[Paraview] Paraview-Wiki: OSMesa

[Burlen Loring]

Hi Gerrit,

The code on the Wiki has been tested with PV 4.0.0, but it sounds like 
it no longer works. The issue is that if you do not put *something in 
the GL library then CMake will fill it in with the system libGL. That is 
the wrong thing to do when using OSMesa and can lead to run time issues 
if you don't set LD_LIBRARY_PATH. In recent builds I've been putting 
libOSMesa in place of the empty string and that has worked. We can 
update the Wiki, however the real solution will be to remove linking of 
libGL and X11 libraries when using OSMesa.
