I managed to resurrect a CMake bug regarding FindGLUT and environment variables. The modules FindOpenGL and FindGLUT do not have maintainers, so the code to discover these libraries ala CMake is languishing. I plan to update these modules, so that they work well in the present day, and I also want to field test a FindGLEW module. But in the future, I'm not ready to be a maintainer for them. My energy and foci are transitional; I can fix this now, I can't promise to fix things later. Are any of you CMake-oriented people interested in being maintainers? Without a maintainer, the quality of these basic CMake querying capabilities is going to suffer.
