Some scripts to help migration of legacy code to the Qt 6.6 qml module system.

It's probably necessary to adjust this script but it should be a good starting point.

The script helps to convert code structured in the "old way":

[https://doc.qt.io/qt-6/qtqml-syntax-directoryimports.html]

to code structured using the cmake qt_add_qml_module command:

[https://www.qt.io/blog/whats-new-for-qml-modules-in-6.5]

The script writes a CMakeLists.txt for each directory containing .qml files.

It also outputs a shell script fix_imports.sh containing replace commands so that code like:

import "../.."
import "../foo"

is changed to:

import ui
import ui.foo

The script follows the proposed directory structure, so if the project directory is foo, the qml files should be located in foo/ui, foo/ui/module1, .... This will make tooling / QtCreator work without further settings.

Please note that any singleton component containing the pragma Singleton annotation must be added to the CMakeLists.txt manually:

set_source_files_properties(
  MySingleton.qml
  MyOtherSingleton.qml

  PROPERTIES
    QT_QML_SINGLETON_TYPE TRUE
)

This script enables cmake unity builds for all the generated CMakeLists.txt. While this does not make much difference for incrementals builds, it significantly saves time in rebuilds of a project.
