when trying to run the planarize\_quads.py (or actually any of the scripts).  
Any hints how to avoid this?  
Thanks!

there is a problem with the build of the boolean functions on windows because of the CGAL dependency. would you mind filing an issue about this? helps to remind us to take care of it…
