Oh, forgot that: yeah, I compiled CGAL between steps 2 and 3. :)
The file /home/mm/.local/CGAL-3.8/lib/CGAL/CGALConfig.cmake exists and the
mentioned line looks like this:
set(CGAL_INCLUDE_DIRS  "/home/mm/.local/CGAL-3.8//include" )
So, this looks just fine and is the correct path.

I'm kind of out of ideas... I compared the explicit compiler lines for the
file that includes the CGAL things. Here the includes in the file
gamutmapping2destimator.cpp:
#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/point_generators_2.h>
#include <CGAL/algorithm.h>
#include <CGAL/convex_hull_traits_2.h>
#include <CGAL/convex_hull_2.h>
#include <CGAL/Exact_predicates_exact_constructions_kernel.h>

and here the compiler line:

It was the same for both, ubuntu CGAL and own compiled CGAL.

But, inspecting the above compiler line, Philipp might be right that the
compiler is still not searching in the right place for include headers...
But I have no idea why or how I should change that? Adding the explicit path
/home/mm/.local/CGAL-3.8/include to $PATH seems a bit weird, as you normally
don't have to do that for other libs...?
