[Insight-users] SNAP: Mac OS X and : GL/glu.h ==> OpenGL/glu.h problem.

[Mike Jackson]

VTK uses the following in their toolkit:

VTK/Rendering/vtkOPenGL.h

#ifndef __vtkOpenGL_h
#define __vtkOpenGL_h

#include "vtkConfigure.h"

#if defined(__APPLE__) && (defined(VTK_USE_CARBON) || defined 
(VTK_USE_COCOA))
# include <OpenGL/gl.h> // Include OpenGL API.
#else
# include "vtkWindows.h" // Needed to include OpenGL header on Windows.
# include <GL/gl.h> // Include OpenGL API.
#endif

#endif

and the opengl seems to work fine in there. Maybe SNAP should do  
something similar.
