Copyright license applies specifically to a piece of code, rather than a 
project, so you would be responsible for the piece of code (i.e. the 
exact version) you distribute. Future versions released by CGAL have no 
connection to that. Additionally, while a license is allowed to change 
in later versions (as it did between 3.x and 4.x), the LGPL license with 
your version's code is irrevocable [1], so your reference remains 
whatever it says in the version of the library you distribute. Of 
course, I am just commenting on the GPL aspects -- as I'm not a lawyer 
(IANAL) nor a member of the CGAL Project, you should double-check any 
ambiguous decisions with somebody qualified! Similarly, Patric and 
others, please comment if you feel anything here is not as expected.

All the best,
Phil
