QtDesignStudio/QMLProjectFileFormat

With Qt Design Studio 4.5 the project structure did change.

With Qt Design Studio 4.5 we changed the project structue. The goal was to have only a single import path (./) at the root of the project. This is better in line with the QML compiler and QML tooling. (https://doc.qt.io/qt-6/qtqml-qtquick-compiler-tech.html)

The default import path is now "./" the root folder of the project, since this better matches with the requirements of the QML compiler and tooling around QML. Before there were usually two import "imports" and "assets_imports". Also relative URIs between modules are now the same in QDS and in the compiled C++ application.

The default project module is now in ./ProjectName instead of imports/ProjectName.

Assets are now imported to "Generated" instaed of "assets_imports". QtQuick3D assets are now in Generated/QtQuick3D and Generated.Effects instead of e.g. assets_imports/QtQuick3DAssets.

Because of the different import paths the (relative) URIs of resouces like meshes are not the same when running the project in Qt Design Studio and the resulting C++ application. The solution is to either avoid referencing assets (files like .mesh files) between modules or moving to the new project strucuture.

Adjusting the project strucuture for legacy projects:

Move the project module from "./import/ProjectName" to "./ProjectName". The same applies to any other module in imports. The URI is not affected by this.

Move all modules from "./assets_imports" to "./Generated". Unfortly this also requires adjusting the import URIs throughout the project.

Project structure since Qt Design Studio 4.5:

ProjectName -                                     ### Folder containing the project
           ProjectName                           ### Default QML module with the same name as the project
           ContentProjectName                    ### Folder with the main QML files. Contains the project name, so it beomes unique, since in the C++ project this is a QML module
           Generated                             ### Folder containing all generated QML modules from 3D import, content libarry and design systems
