I have a project licensed under the EUPLv1.2 license, and I want to incorporate GPLv3-licensed code in it. However, due to the GPL's copyleft, that is not legally possible.
Is it possible to dual-license the project with both licenses (EUPLv1.2 and GPLv3) to allow for the GPLv3-licensed code to be incorporated in it, even if the code is not compatibledespite incompatibility with one of the licenses (EUPLv1EUPLv1.2)?
