Dear Laurent ,
Hi ,

I went to build folder and delete all the past exist file. and then use Cmake-gui to create the build again . and then configure 2 times and then generate .I test this procedure 4 times with CGAL_dir from source or CGAL-dev path . and in Debug or release mode .
this is not any change in the output error and I usually see this :
I have typed  make VERBOSE=1 clean AABB_demo
 too . this is the result :

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.
