Building Qml plugin statically as a lib fails

[Besajia]

Hi, I want to deliver my QML plugin as a lib (not .so).
Building is ok, but when it is linked to main app, the QML module is not imported

QQmlApplicationEngine failed to load component
qrc:/app/main.qml:7 module "Navigator" is not installed

I did according this instruction
Re: [SOLVED]Deploying a Qt Quick 2 plugin with a static build
but it is still not successful.

Is there more updated manual how to make it work?
