Please add qwt license to profiles/license_groups.
It seems to be a free software license (LGPL with additional exceptions) and can probably be added to GPL-COMPATIBLE licenses.
@Licenses team: This is not explicitly approved by the FSF. However, if we treat it in the same way as the other "(L)GPL with exceptions" licenses then indeed it should go to GPL_COMPATIBLE.
Added to GPL-COMPATIBLE.
I've also added a comment that GPL and LGPL with exceptions should go to this group (even if not explicitly approved by the FSF), because they are more permissive than the licenses they are based on.
