-I apologize in advance that my very first Sage trac ticket is a huge wishlist item.

-I would be interested in a Sage package for CGAL, the Computational Geometry Algorithms Library. http://www.cgal.org/index.html
+This ticket adds a preliminary Sage package for CGAL, the Computational Geometry Algorithms Library. http://www.cgal.org/index.html
It is a huge package. My main interest, right now, comes from a need for fast data structures for polyhedral complexes in low dimension / piecewise linear functions in several variables.
-By a web search, I found that in 2009, there was intermittent interest in making such a Sage package. [https://groups.google.com/forum/#!topic/sage-devel/35g7UicEKvo](https://groups.google.com/forum/#!topic/sage-devel/35g7UicEKvo)

One of the concerns at the time apparently was CGAL's licensing. However, CGAL has changed its licensing terms since then; it now appears to be released under some combination of GPL and LGPL, version 3 or later.

Nice! Testing right now.
There are also various boost libraries needed...
(EDIT: for which we have a package)
The Sage cmake
package is installed. Why don't we use the system one if it is there (as we do for gcc)?
At least I am able to compile simple CGAL projects within Sage. However, having some cython code using CGAL looks less trivial.
There's https://pypi.python.org/pypi/cgal-bindings/0.0.7 (haven't tested)
