Will look in next time, about Windows it becomes always a bit harder, as there a own CMakeLists.txt need created.

Would it be also OK to use https://lib.openmpt.org/files/libopenmpt/src/libopenmpt-0.6.0+release.autotools.tar.gz (if API compatible) or https://lib.openmpt.org/files/libopenmpt/src/libopenmpt-0.5.15+release.autotools.tar.gz

Sure, newest versions would be great, but ideally, the flatpaked version should match the one in upstream
