[vtkusers] Building VTK 6.3.0 with X11 on Mac El Capitan

[David Gobbi]

Hi James,

Assuming that you have installed xquartz and that you have all the X11
headers and libraries in /opt/X11, you have to tell cmake to use the OpenGL
that comes with X11:

OPENGL_INCLUDE_DIR:PATH=/opt/X11/include
OPENGL_gl_LIBRARY:FILEPATH=/opt/X11/lib/libGL.dylib
OPENGL_glu_LIBRARY:FILEPATH=/opt/X11/lib/libGLU.dylib

Otherwise VTK will link to the framework OpenGL, which doesn't include glx.

Even with the above, there are no guarantees that VTK will work with X11 on
OS X.  But it should at least get you past the link errors.

 - David
