[vtkusers] Linux: Nvidia + Mesa for offscreen

Hello,

I would like to use my Nvidia OpenGL drivers
for onscreen rendering and use Mesa for
offscreen rendering under linux. I am
not sure how to communicate this to
the ccmake program when configuring
vtk. Any advice? Do I need the
VTK_MANGLE_MESA option? (this is
troublesome as my debian system tries
to remove my nvidia drivers every time
I try to install a package that has
gl_mangle.h). I have tried to build
with the VTK_OPENGL_HAS_OSMESA option,
and it builds successfully, but when I
try to run I get symbol errors (I assume
it is looking in the Nvidia libGL
for Mesa stuff). Has anyone managed to
do this successfully?


Thanks,
