cmake cross compile windows binary from WSL2 using clang/llvm - linux

Question

I'm tring to compile windows binary from WSL2 using clang and llvm using this cmake file:

cmake -S . -B build_windows -G 'Ninja Multi-Config' -DCMAKE_TOOLCHAIN_FILE='cmake/toolchains_windows.cmake'
However this configuraion fails to find libraries

I thought providing these paths to CMAKE_FIND_ROOT_PATH handles finding libs/headers but it didn't.
So I added this code to the cmake/toolchains_windows.cmake
include_directories(
"/mnt/c/Program Files/Microsoft Visual Studio/2022/Community/VC/Tools/MSVC/14.34.31933/include"
"/mnt/c/Program Files (x86)/Windows Kits/10/Include/10.0.22000.0/ucrt")
link_directories(
"/mnt/c/Program Files/Microsoft Visual Studio/2022/Community/VC/Tools/MSVC/14.34.31933/lib/x64"
"/mnt/c/Program Files (x86)/Windows Kits/10/Lib/10.0.22000.0/um/x64"
"/mnt/c/Program Files (x86)/Windows Kits/10/Lib/10.0.22000.0/ucrt/x64")
Now it can compile hello world program!
cmake -S . -B build_windows -G 'Ninja Multi-Config' -DCMAKE_TOOLCHAIN_FILE='cmake/toolchains_windows.cmake'
cmake --build build_windows -v --config Release
# it works!
However when I try to use -fsanitize=address,undefined it fails.

clang_rt.asan-x86_64.lib is present in /mnt/c/Program Files/Microsoft Visual Studio/2022/Community/VC/Tools/MSVC/14.34.31933/lib/x64 so I don't know why this is not working...
