[Interest] qt_add_qml_model() dependency issue

[Sze Howe Koh]

Sounds like https://bugreports.qt.io/browse/QTBUG-106683 which was already
fixed in Qt 6.5.2.

However, there's still a related issue outstanding:
https://bugreports.qt.io/browse/QTBUG-115166

As a workaround, use Ninja instead of Makefiles, since Ninja wasn't
affected by these issues.
