Qt Approved Directory layout convention

[RangerQT]

In the blog post it refers to a directory layout convention (https://www.qt.io/blog/introduction-to-the-qml-cmake-api) but I have not found many useful references that actually say what they want. I found some reference to an example of My/Extra/Module which I assume means

My (project root directory)
main.cpp
main.qml
Extra (directory)
Module (module as in module.qml

And a URI for the Extra directory module would be URI extra.module.

If I use this blog post it implies that my QML app will be built and an executable created which contains everything it needs to run so I can go to main.qml and do an import extra.module???

Thanks.
