[vtkusers] OpenGL linking issue on Mac 10.5

[Wes Turner]

Alexandre,
Try adding the entire string
"-Wl,-dylib_file,/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib"
to CMAKE_EXE_LINKER_FLAGS, CMAKE_SHARED_LINKER_FLAGS, and
CMAKE_MODULE_LINKER_FLAGS.

It works for me, last I checked.

- Wes
