CMake LLVM and Windows XP toolset

Because of performance reasons with the SIMRegister classes we switched to LLVM on windows. It worked great with Visual Studio 2019 and it’s LLVM support.

Things started to get complicated when i tried to build with CMAKE and using following toolset extensions that allow LLVM to build with the windows XP toolset and building with a LLVM installation outside of VS:

I called it this way:
cmake -B cmake-build -DCMAKE_PREFIX_PATH=../juce/install -DCMAKE_BUILD_TYPE=Release -A x64 -T LLVM_v141_xp

It compiled but i get a fatal error while it tries to link (LNK1107 error).

Did anyone manage to do this? Are there other ways to build against the xp toolset with LLVM?
