If I use Unix Makefiles as the generator and then execute make install.
First I get the error
/Users/mv/Desktop/pv/build/superbuild/qt5/src/qtbase/src/platformsupport/fontdatabases/mac/qfontengine_coretext.mm:833:20: error: qualified reference to 'QFixed' is a constructor name rather than a type in this context
return QFixed::QFixed(int(CTFontGetUnitsPerEm(ctfont)));
And after removing the prefix QFixed::
I execute make install again and get a lot of errors, example:

I suspect that build failures will happen because when Apple changes things, Qt is quite sensitive to it, so newer macOS releases probably can’t build old Qt releases.
