Files: src/ext/CGAL/OGL_helper.h Copyright: © 1997-2002 Max-Planck-Institute Saarbruecken (Germany) License: GPL-3+ Comment: This used to be derived from the original QPL'd OGL_helper.h from the CGAL library. The library got re-licensed to GPL-3+ (or LGPL-3+, for other parts) in its 4.0 version, with no significant changes to the OGL_helper.h file. So while the file in here claims to be QPL derived, it can be equivalently thought of being derived from the new OGL_helper.h in CGAL4, which can be obtained from https://gforge.inria.fr/frs/download.php/30225/CGAL-4.0-beta1.tar.gz and states in its current license section exactly what is here shown in this DEP5 file's License: section.
