I try to configure to LLM to build with mold as the linker. I use clang from LLVM 19 windows release.
My cmake invocation is `cmake -S . -B build -DLLVM_USE_LINKER=mold -DLLVM_PARALLEL_LINK_JOBS=1`
I also tryed `CMAKE_LINKER=mold` and setting `-fuse-ld=mold`
still:

notice the `-Xlinker /subsystem:console -fuse-ld=lld-link` at the end
