Well, it is dependent on users configuring their system to compile with
ccache. Normally, this happen automatically when you use the symlink trick
I wrote about earlier.
In this case, however, your makefile is explicitely requesting a specific

If you want to use ccache, you need to either:
1- change this to point to g++ without the path, and rely on the symlinks to
pick up /usr/bin/ccache instead of /usr/bin/g++
2- change this variable to invoke g++ through ccache:
CGAL_CXX = /usr/bin/ccache /usr/bin/g++
Both of these methods are described in more details in the ccache manpage.
