Well, yes, that's why I'm talking about doing this only if using the
same prefix as Qt as the install prefix. In practice, if you're
installing to /usr you want things to be in the correct place.

QML plugins are a good example why the current behavior is quite
broken. If you install an application to /usr, you don't expect to
need to specify weird a QML_PLUGIN_PATH for the app/framework to work.
