I post a message in CGAL (library that I use) mailing list and Andreas Meyer said:
"These are for caching a whole translation unit and wont help for CGAL, because here, most programs only have one translation unit (one C file,
which includes everything else)."
What is your opinion?

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

If you want to use ccache, you need to either:
1- change this to point to g++ without the path, and rely on the
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
