Guide how to convert "old structure" DS project to existing one.

In https://doc.qt.io/qtdesignstudio/studio-designer-developer-workflow.html it is mentioned that:
"
Qt Design Studio 4.4 and earlier versions have a project structure where different explicit import paths such as imports or asset_imports reference assets such as images or mesh files separately in their own scope. So, linking them from one module to another does not work in the generated CMake-based C++ application. Such cross-modular references are not considered good practice. Since Qt Design Studio 4.5, this issue has been solved. All the import assets are now bundled in the same folder, so the CMake generation works properly.
"
There is currently no official guide how to convert this kind of "Before DS 4.4" project into existing project format. Wiki page https://wiki.qt.io/QtDesignStudio/CMakeExporter has some pointers but there should be step by step guide for customer to update their project.
