OpenSceneGraph/CMakeModules/FindGLCORE.cmake
Robert Osfield ecd26f9f5b From Paul Martz, "There is no standard place for gl/glcorearb.h on Windows. Previously, the only way to get OSG to build for core profile was to append an additional include directory ("/I") onto the CFLAGS variables This submission adds a FindGLCORE.cmake script so that the path to gl/glcorearb.h can be specified with a variable, GLCORE_ROOT, either in CMake or the environment.
Currently this submission is Windows-only. I don't think OSX or Linux require any help in locating gl/glcorearb.h. But if they do, this submission can be easily modified.

Files:
 - "CMakeLists.txt" is the top-level file.
 - FindGLCORE.cmake" and "OsgMacroUtils.cmake" go in CMakeModules.
