Hmm, however, Qt itself is licensed under GPL 3, and LGPL 2.1. I
wonder whether this is compatible with GPL 2?
According to GPL compatibility table [1] LGPL 2.1 is compatible with
GPL 2, but I don't understand how Qt can be licensed at the same time
also under GPL 3, and what that means for compatibility...
