Comment (by jmon12):

 Hi!

 The `use_xcode yes` trick of course doesn't work if Xcode is not fully
 installed (e.g. only CommandLineTools). What would be the way to go in
 that case? I have to admit that I don't understand why this trick actually
 works.

 Note that `xcrun --show-sdk-path` or `xcrun --sdk macosx --show-sdk-path`
 work, but `xcrun --sdk macosx12 --show-sdk-path`doesn't work even though
 in my case `MacOSX.sdk` points to `MacOSX12.3.sdk`. Might it be the cause
 of the problem? How is `xcrun` actually called and by what?

 I attach main_py-pyqt5.log which might bring some insight.
