If you create a derivative work of GPL code and non-GPL-compatible-licensed
code, you will find that there is at least one requirement in the
incompatible license that contradicts the GPL. So that means you cannot
comply with both the GPL and with the other, incompatible license when
distributing the derivative work. Distributing a work without complying with
the relevant licenses is an infringement of copyright and/or a violation of
the license contract (depending on jurisdiction).
