This revision of the OpenGL Samples Pack 3.3 should fix Linux build. It also introduces few changes so that I can work in parallel on OpenGL 2.1 samples, OpenGL 3.3 samples and OpenGL 4.0 samples: Samples in a pack can run with different OpenGL version and, for example, changes of OpenGL 2.1 samples can be apply on OpenGL 3.3 samples with a simple merge.
Thanks Git!
