Instead of copy-pasting an existing CMakeLists.txt, you can run the script 
$HOME/CGAL_3.8/scripts/cgal_create_cmake_script in your project, to create a 
new CMakeLists.txt.

If your project has severall .cpp files used to build a single executable, 
you 
can put all the .cpp files names in a single macro 
'create_single_source_cgal_program' (that macro is not well named). The name 
of the executable will be the name of the first .cpp file (without the 
extension).
