What would be a good way to make CMake invoke lld-link (or through clang-cl) instead of using `cmake vs_link` in this situation?
We thought about using

```
set(CMAKE_${LANG}_SIMULATE_ID "MSVC")
set(CMAKE_${LANG}_COMPILER_FRONTEND_VARIANT "GNU")
```

but I don't feel great about changing variables that are not suppose to change.
