Subject: [PATCH] fix regression about MOC compilations

The commit b05e1e9e4604aa8663366f6f6aed416c215cce7e was indeed the
cause of the regression. But the root cause was an incorrect
usage of `qt6_generate_moc`.

The addition of `TARGET ${plugin_name}` triggered the use of the
property `INCLUDE_DIRECTORIES` of the target.

See https://doc.qt.io/qt-6/qt-generate-moc.html#arguments
