GLTools from OpenGL SuperBible 5th

Hi everyone,
I wonder if someone has managed to get the GLTools from the OpenGL SuperBible 5 working along with OF.
There are quite a bunch of useful functions (like ShaderManager) that I would like to use inside my OF projects but there seem to be some conflits… specifically:

  
  
gl.h included before glew.h  
glext.h included before glew.h  
  

Here you can find the source code for SB5 and in particular the GLTools library:

Thanks
