package cgal: fix build failure when qt is present

When Qt happened to be present, CGAL would fail to build. This
happened when moc was called on certain files that included
has_binary_operator.hpp from boost:

<includedir>/boost/type_traits/detail/has_binary_operator.hp:50:
Parse error at "BOOST_JOIN"
