qt_generate_deploy_qml_app_script does not deploy dependencies of a QML Module thats not in a subfolder

Hi,

I noticed that the script generated by qt_generate_deploy_qml_app_script does not deploy all dependences when the application links to a static QML Module target that is not a child of the application directory.

Given i have the following project structure:

- app/
   CMakeLists:
            qt_add_executable(A)
            qt_add_qml_module(A)
            target_link_libraries(A PRIVATE B Bplugin)
- module/
   CMakeLists:
           qt_add_library(B STATIC)
           qt_add_qml_module(B)

We can build and run the project like usual inside QtCreator. In my case in particular, only library B has imported QtQuick.Dialogs. When I deploy it:

..\test_qmlmodule_deploy> cmake --install build\Desktop_Qt_6_7_2_MSVC2019_64bit-Debug\

the files for QtQuick.Dialogs are missing:

..\test_qmlmodule_deploy> install\bin\test_qmlmodule_deploy.exe
QML debugging is enabled. Only use this in a safe environment.
QQmlApplicationEngine failed to load component
qrc:/qt/qml/test_qmlmodule_deploy/Main.qml:9:5: Type TestComponent unavailable
qrc:/qt/qml/mymodule/TestComponent.qml:2:1: module "QtQuick.Dialogs" is not installed

If I import QtQuick.Dialogs in the main application QML, i don't have this issue. So it seems that the qmlimportscanner does not detect the imports from dependent QML libraries. Additionally, if I put the module in a subdirectory instead of side-by-side it is also working correctly.

As far as i read the documentation and guides there is also no script or addional command that should be specified when defining a QML module that is neccessary to deploy successfully.

I only tested it on windows for now, but I will test it on Linux aswell.

Attached is a simple project that demonstates the situation.

Thank you and Best Regards
