I looked at the FindDevIL.cmake file, and if I understand it correctly 
it might be wrong for Windows.  On Linux, the main library is called 
libIL.so.  On Windows, however, the corresponding import library is 
called DevIL.lib.  The FindDevIL.cmake file seems to only consider IL 
and not DEVIL as the valid name for the library.  I added DEVIL to the 
NAMES entry for the IL_LIBRARY's FIND_LIBRARY command and CMake 
successfully configured the project.  I'm wondering if I should enter a 
bug against this module.
