Qt header files not recognized

Environment

• OS and Version: macOS 14.1.2
• VS Code Version: 1.85.0
• C/C++ Extension Version: v1.18.5

Bug Summary and Steps to Reproduce

Hello,
I have a minimal Qt sample project based on CMake. Qt is installed locally and in my local settings.json I refer to my local Qt installation path:

{
    "cmake.configureArgs": [
        "-DCMAKE_PREFIX_PATH=/Users/stefano/Qt/6.5.1/macos/lib/cmake/"
    ]
}

In CMakeLists.txt I search also for the packages:

find_package(Qt6 COMPONENTS Core REQUIRED)

target_link_libraries(${target} Qt::Core)

It builds successfully (!), but when I open TestClass.h, I get following error message:

'QtCore/qobjectdefs.h' file not found

Strangely, I can click with CMD + click into the header file, never the less, VS Code gives me the said error message!

CLion in the other hand does not have this problem.

I have attached my minimal project. I hope, you can help me.

Thanks in advance!
