FTBFS: Qt UI requires nonexistent QPA header

Although configure completes without errors:

../../../../modules/gui/qt/util/csdmenu.cpp:25:10: fatal error: QtGui/qpa/qplatformnativeinterface.h: Aucun fichier ou dossier de ce nom
   25 | #include <QtGui/qpa/qplatformnativeinterface.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

This is on Debian unstable with Debian-provided Qt6.
