Very hard to build with cmake

[Wim4rk]

Hi,
Trying to build from source. Lots of problems have been solved. The latest one reads like this:
My command: $ cmake -P build.cmake -DCMAKE_BUILD_TYPE=Release

/musescore/src/importexport/musicxml/internal/musicxml/musicxmlsupport.h:27:10: fatal error: QAbstractMessageHandler: No such file or directory
   27 | #include <QAbstractMessageHandler>

I'm on Ubuntu 20, I use Qt5.15.2.

Is there a Github somewhere? Would somebody hold my hand for the build process?

So, missing a library. In case someone has the same problem mentioned above. Install this - not very obvious - package.

sudo apt-get install libqt5xmlpatterns5-dev

Is this something that needs to be done for any device or just Ubuntu?
