That is normal. As the README file of that directory says, it is only there 
for use on Microsoft Windows.

Dependencies of CGAL are external to CGAL, and must be installed by users. In 
your case, GMP, MPFR, and Boost are installed by the package manager of 
Ubuntu. And CMake found them in /usr/include dans /usr/lib or /usr/lib64/. 
That is normal.

You must set CGAL_DIR yourself to the directory where you have configured and 
build CGAL sources.

You just have to type 'make' in the directory where cmake has generated the 
"Makefile" file.

I would like to the see the result of the following command:

  make VERBOSE=1 clean AABB_demo

It will show all compilation commands, and will help to understand.
