Since MuseScore 3.6.1 doesn't even start compiling with Qt 5.15 (see https://musescore.org/en/node/299758), I moved back to Qt 5.12.8 and it gives a different error right at the beginning of the compilation process:

No rule to make target 'all.h', needed by 'CMakeFiles/mops1'. Stop.

The version 3.4 used to compile fine with this same Qt version, same installation.

System: Linux Ubuntu 20.04
Qt 5.12.8
QtCreator 5.14.0

After switching to branch 3.6 and switching back to 3.6.1, I managed to get it to start compiling and to get to another error:
