+WATCH OUT! On Linux it is quite frequent to have both Mesa and proprietary
+           openGL libraries installed. This may lead to big problems at
+           runtime if the linker picks the wrong library. It is often the
+           the case between the static (libGL.a) Mesa library and the dynamic
+           (libGL.so) NVidia library. It is very important to assert that
+           the link is done with the library matching the openGL driver
+           loaded in the X server.
