to be more specific, your entries are separated by ":" thus you
may have to split the entries using some CMake scripting
(look at the string command) before giving the separate entries into
INCLUDE_DIRECTORIES.

However from the value you showed us:
:/home/doriad/src/glui-2.36/src/include/GL:/home/doriad/src/CGAL-3.5/include:/usr/lib/qt-3.3/include/

May be you can do it in a more "CMake-ish" way using

for OpenGL that would be:

FIND_PACKAGE(OpenGL)
INCLUDE_DIRECTORIES(${OPENGL_INCLUDE_DIR})

etc...

if the FindOpenGL.cmake script given with CMake does not suits your needs
then you may craft your own.
