QML with VS Code - Builds but fails at runtime (Windows)

Hanjo

Hi I am new to QML and CMake. And can't figure out what is going wrong on Windows.
After a whole weekend of trying all kinds of rituals I am at my ends, I hope maybe some here got some pointers for me?

In VS Code I can build it but once I try and run it it throws the error that the plugins are not initialized.
I tried to use windeploy.exe to get the right dll's but then it only says it found them but still not wants to use them???

My project setup:
I am using VCPKG in manifest mode to download the following ports:

qtdeclarative
qtbase
qttools
qt5compat

(I tried downloading just "qt" but then it fails on the QTwebengine and I just want a desktop application so I thought it was okay?)

I also have QT 6.8.3 installed on my system through the QT online installer.

)


qt_generate_deploy_qml_app_script(
    TARGET DeckRC
    OUTPUT_SCRIPT deploy_script

install(SCRIPT ${deploy_script})

I compiled it with MVSC 2022
