OpenCV & OpenCV contrib build Windows 11 - c++

Question

I'm trying to play around with OpenCV and OpenCV Face (a contrib module). Unfortunately I'm bound to a Windows devivce. Furhermore the OpenCV Windows download does not contain the contrib modules e.g. the face one which I need, so I tried to build OpenCV with OpenCV contrib myself. The project itself should run on Windows & Linux.
If I use the prebuild OpenCV files (except the face module), everything works just fine.
Windows specs:

CMake build command respectively with and without -DBUILD_opencv_world
cmake -B "build" -G "Visual Studio 17 2022" -A x64 -DCMAKE_BUILD_TYPE=RELEASE -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=OFF -DOPENCV_GENERATE_PKGCONFIG=ON -DWITH_OPENGL=ON -DWITH_QT=ON -DBUILD_opencv_python2=OFF -DBUILD_opencv_python3=ON -DBUILD_JAVA=OFF -DBUILD_FAT_JAVA_LIB=OFF -DBUILD_DOCS=OFF -DVIDEOIO_PLUGIN_LIST=all -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules -DBUILD_EXAMPLES=OFF .
I encountered two error cases depending on the CMake settings
1. BUILD_opencv_world=ON
If I run cmake --build build --config Release to build the libs it stops kind of after building opencv_world. If I open the Visual Studio solution to build I get error messages related to opencv_world
Error output (cmake --build runs until the very first marked line and stop without any output, so first I thought everything built without error)
Error list
2. -DBUILD_opencv_world=OFF
Because I rooted the build issue cause at the opencv_world module (which normally comes with the prebuild binaries), I tried to build without them. This build works but then I get undefined reference error of the linker.

Edit
I also tried the combi ninja + clang but also no luck. Here it fails even earlier
