I have been struggling with this problem for a few days now. Last week my
homebrew
installation quietly updated Qt to v6 (brew upgrade). Since then I can't
compile LyX
anymore. Unfortunately I learned about the "brew pin" command too late.
When running .\configure I get the error message: "configure: error: cannot
compile a
simple Qt executable. Check you have the right $QTDIR."
I tried to set $QTDIR to the following directories:
/usr/local/Cellar/qt
/usr/local/Cellar/qt/6.0.2
/usr/local/Cellar/qt/6.0.2/bin
/usr/local/Cellar/qt/6.0.2/lib
/usr/local/opt/qt
/usr/local/opt/qt6
/usr/local/opt/qt@6
I also tried to downgrade to Qt5, but this also did not solve the problem. I
have
noticed that Qt5 is not installed in the folder "qt" anymore (this is now the
place,
where Qt6 is installed), but in a folder with the name "qt@5".
I also deleted my local repository and started from scratch. Also no success.
I appreciate any recommendation what to do.

Trying to adapt cmake to qt6, I get compile errors

This will take some work. There's some info here:
https://doc.qt.io/qt-6/portingguide.html
Maybe we should make this a post 2.4 priority, though of course work on
it could start now in a branch.
