After a lot of work by many contributors, we finally managed to merge the Qt6 branch into main. This means you can build the master branch with Qt6 instead of Qt5 now.
Note that nightly builds are still using Qt5 for now, since Qt6 support is still fairly new and may be less stable.

edit: a minor correction - windows MSVC builds seem to have Qt6 enabled by default, so you windows users can try Qt6 without compiling it yourselves ^^
