[Paraview] help w/ glXGetProcAddressARB not declared

I took another look at the CMake files and did find a slight problem.
It turns out that when you change the directory of the OpenGL include
files, the build was not checking again to see if the prototype exists
for include files in the new directory.  Is it possible this is what
happened to you, Stefan?  You can check by deleting
VTK_GLX_GET_PROC_ADDRESS_ARB_PROTOTYPE_EXISTS_TESTED from your
CMakeCache.txt.  If the test gives the correct answer this time, that
was probably the problem.
