Looks like I need to export an appropriate path for the grefsen QML module to be found:
screen.qml:

import QtQuick 2.6
import Grefsen 1.0

Any advice on where I should point it please? Never really used QML before - does it get the custom module from a shared library, or is it actually looking for a QML file?

Thanks!

I stand corrected, I had missed that that was a resource path. Although I presume it amounts to the same, it's not getting pointed to itself in order to load in the plugin at runtime.
