Qmake not found (in neon)

on fresh kde neon with plasma6:

qmake command gives not found, but may be installed via qtchooser package…

same is true for qdbus or qml

all binaries are in:
/usr/lib/qt6/bin/

but this is not in $PATH

is this intentional?

Was it different on Plasma 5 with neon? If yes then its likely a bug → bugs.kde.org

qmake is for qt 5. Does qmake6 work?

in that case qmake ist just a symlink:

christian@neon:~$ /usr/lib/qt6/bin/qmake -v
QMake version 3.1
Using Qt version 6.6.2 in /usr/lib/x86_64-linux-gnu
christian@neon:~$ ls -l /usr/lib/qt6/bin/
