#NOTE:  In Windows I haven't had much luck getting the FindGLUT script to work correctly. 
#The easiest solution has been  to install GLUT alongside OpenGL, which is already in the system path.
#This means glut.h and glut32.lib go in the 'include' and 'lib' folders within  Microsoft Visual Studio 8\VC\PlatformSDK\ 
#Also, glut32.dll goes in C:\Windows\System. Using C:\Windows\System32 doesn't seem to work

#Tell CMake the paths for OpenGL and for PolyVox (which is just relative to our current location)
INCLUDE_DIRECTORIES(${OPENGL_INCLUDE_DIR} "../../library/PolyVoxCore/include")
