Can't compile CGAL code

I can't compile this code from CGAL docs, got the following error:

$ g++ apply.cpp -lCGAL -I/usr/local/include -o a.out
In file included from /usr/include/CGAL/Constrained_triangulation_2.h:28:0,

I installed libcgal-dev, libcgal-demo, g++ and cmake from apt. G++ version 5.4.0-6ubuntu1~16.04.9

C/C++ isn't clear about version errors, this code example is from CGAL 4.12, my library was 4.7.

I had to upgrade my linux for 18.04 to get a recent libboost version in a stable way, then I used the libcgal 4.11 from the official repository for less overhead compiling and maintaining the library.
