Disclaimer: I haven't tried this.

You will have to patch and rebuild the QML plugin. This is because it is 
verifying that the correct import uri is used. You will need to patch the 
source to accept the harbour.appname.QtPositioning uri.

It is also not just a mater of shipping the QML plugin with your application, 
you will need to ship all dependencies not approved by Harbour. For Qt 
Positioning this would also mean the Qt Positioning C++ library as well.

The plugins.qmltypes file is not important at run-time. It is used by Qt 
Creator for syntax highlighting and code completion.

QQmlEngine::addImportPath() or set QML2_IMPORT_PATH
