I think this is a red herring. configure (which has a nicer command line, and therefore still is the officially recommended way, see https://doc.qt.io/qt-5/configure-options.html) just calls cmake, and the used cmake arguments are printed on the very first line.

Can you paste the full output of the configure tool? You can redirect the output to a file:

  ..\qt5\configure.bat -prefix ..\qt6-win64 -developer-build -opengl >configure.log 2>&1

Regards

Kai

Ninja isn't mandatory, but a good idea.

Don't use the configure scripts any more. Please use CMake directly.

The CMake logs aren't useful if the problem isn't compiling something. Please 
paste the entire output from CMake.

We may need a run with --trace-expand to find out the decisions it made.

I spent over one hour to get past the "cmake" step yesterday on macOS. I have 
not started on Windows. Will probably do that in June.
