Installing a QML module created by qt_add_qml_module

When using qt_add_qml_module I found no way to install a created QML module so that another project can import and use it.

In KDE we have various "library" projects that install QML imports to be used in other projects, most prominently https://invent.kde.org/frameworks/kirigami

After reading https://doc.qt.io/qt-6/cmake-build-reusable-qml-module.html and https://qt_add_qml_moduledoc.qt.io/qt-6/qt-add-qml-module.html I don't see how I would use qt_add_qml_module in Kirigami to allow other projects to import the created QML module
