when doing a build if the qt5 super-repository, the permission plugins are not loaded. e.g. "declarative-camera" does not load the camera plugin.

the issue seems to be two-fold:

• QDarwinCameraPermissionPlugin is not linked into the target (seems that the finalizer is not installed proprely or does not pick it up)
• when it is linked manually, it is not automatically imported, as the `$<$<AND:${separate_request_genex},${has_usage_description_genex}>:${permission_request_flag}>` genex evaluates to "false", because `has_usage_description_genex` evaluates to 0
