Using windeployqt and CMake commands for deployment give different results

Good afternoon everyone.

We are trying to use to copy the qt dependencies of the application not by manually calling windeployqt, but through the use of the corresponding cmake functions (i.e. , which are added by the qt library), namely:

qt_add_executable(...
qt_add_qml_module(...
qt_deploy_runtime_dependencies(...
qt_deploy_qml_imports(... 

and then called

cmake --install . --config Release --prefix ... 

So, in comparison with what happens in the end after calling windeployqt, the result after the specified cmake commands in the qml directory lacks files:

*.qml
*.qmltypes

For example, here are the contents of the directory qml/QtMultimedia/ after calling windeployqt:

qmldir
quickmultimediaplugin.dll
Video.qml
plugins.qmltypes 

and here are its contents after the specified cmake commands and the cmake –install call:

qmldir
quickmultimediaplugin.dll 

In this case, the application seems to launch and work, but there is a lot of functionality, perhaps we do not see something that may not work. Question: Are these files needed in the deployed application or not?

I am also attaching a simple example to test the behavior.
