Building QT 6.2.2 for MacOS – Part 2

In my previous post I described my first attempt to built QT 6.2.2 for MacOS. Probably my mistake was that I did not switch to full XCode with the command:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

and that I used the configuration script with a wrong syntax and missed -- in the command line. Probably the following configuration can be a step to a right direction:

./configure -c++std c++20 -opensource -confirm-license -no-openssl -securetransport -DQT_NO_EXCEPTIONS=1 \
  -skip qt3d -skip qt5compat -skip qtactiveqt -skip qtcharts -skip qtcoap -skip qtconnectivity \
