If you give CMake a full path to the GL and GLU libraries that are not 
the system libraries, then it will use those.  Looks like the STANDALONE 
logic is not quite right for GL.   However, if you edit the 
CMakeCache.txt or give a -D option and set the following cache variables 
to the full path to the libraries in ../i686-linux/lib-release (with 
extension):

OPENGL_gl_LIBRARY
OPENGL_glu_LIBRARY

Then it should work.
