Trying to compile embree on a server, I was notified that I didn't have GLUT installed:
CMake Error at /home2/alecjaco/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:97 (MESSAGE):
Could NOT find GLUT (missing: GLUT_glut_LIBRARY GLUT_INCLUDE_DIR)
I shouldn't need this because I don't care about visualizing the results. To get around this requirement I simply comment out the following line in the top level CMakeLists.txt:
ADD_SUBDIRECTORY(examples)
becomes
#ADD_SUBDIRECTORY(examples)
