Hey Amy and Joachim, thanks for answering that fast! My response comes a bit
late, but I was afk all weekend long.

What both of you said makes total sense and I'd like to follow Amy's
recommendation and compile CGAL from source and link against that.
Unfortunately, it's not working. Setup is like this:
1) downloaded https://gforge.inria.fr/frs/download.php/28501/CGAL-3.8.tar.xz
2) unpacked and called cmake: only option changed is: 
CMAKE_INSTALL_PREFIX = /home/mm/.local/CGAL-3.8/
as that's the place I keep my selfcompiled software.
3) open my project in cmake and set 
CGAL_DIR = /home/mm/.local/CGAL-3.8/lib/CGAL
It's the only CGAL option and originally when I install CGAL through
Synaptic, the folder /usr/lib/CGAL contains the same files, mostly *.cmake
or *.in files.
4) compile my project and get error:
/home/mm/code/src/cv/reflectance/illumestimators/gamutmapping/gamutmapping2destimator.cpp:14:64:
fatal error: CGAL/Exact_predicates_inexact_constructions_kernel.h: No such
file or directory
compilation terminated.
When I search for that file, I can find it in 
/home/mm/.local/CGAL-3.8/include/CGAL/Exact_predicates_inexact_constructions_kernel.h
Any ideas what I am doing wrong?

Thanks for your help!
