The Qt6 package needs to be found before calling
qt_build_internals_set_up_private_api, otherwise it will fail when
using a cross-compiled Qt, because QT_HOST_PATH will not be set.
The error is:
CMake Error at qtbase/cmake/QtBuildHelpers.cmake:341 (message):
You need to set QT_HOST_PATH to cross compile Qt.
