A couple things to suggest - look at the CMakeCache.txt file to make
certain it's point to the correct OpenGL libraries.

Are you using Sun's OpenGL libraries or Mesa? Have you verified that
they are working ok (i.e., tested another OpenGL program other than
VTK)?

You might also look at the output of:

xdpyinfo

and

glxinfo (although this may not be available on Solaris).

Sounds to me like you need to check with your system administrator
about what visuals your system supports.

Good luck.
