How to make Qt libraries a component in cpack installer? - windows

Question

I'm trying to build a Qt installer for my app using CMake and CPack with it's CPackIFW plugin. I'm using Windows. I've defined the main application component and a library, they both appear in the installer and are installed correctly. I also have a CPack pre-build script that runs windeployqt and adds the DLLs required by the application. However, as the DLLs are copied into the same folder as the main executable, I can't make them separate components. Is there a way to separate my artifacts from Qt DLLs and still be able to run the application after installation?
Here's my CMakeLists:
cmake_minimum_required(VERSION 3.22)
project(untitled-bot VERSION 0.1 LANGUAGES CXX)
set(CMAKE_INCLUDE_CURRENT_DIR ON)

It copies the required Qt libraries to the bin directory containing the application exe and they are picked up by CPack as part of the main app component.
Can you help me fix this?
