I tried with the entries above in my autogen.input and I could build LibreOffice.

The same entry in the about dialog of LibreOffice.If I do the same with a downloaded TDF LibreOffice dev-build of 26.8. (run from the shell) I get the information in the about dialog: 'VCL - kf5'It looks as if no or no qt-6 VCL will be build within my local git repo.
Interesting. If you use `--enable-qt6`, my expectation would be that it either builds the qt6 vcl plugin or gives an error.
Do you have a file instdir/program/libvclplug_qt6lo.so after the build finishes? If so, starting with environment variable SAL_USE_VCLPLUGIN=qt6 should result in the qt6 vcl plugin actually getting used. (It's not used by default. The qt6-based kf6 would be used by default in a Plasma 6 session. That one can be enabled with --enable-kf6 and requires some more KDE Frameworks build dependencies.)
