  Log Message:
  -----------
  Explicitly specify CMAKE_AR in WinMsvc.cmake

As of cmake 3.18, cmake changes how it searches for compilers for
Windows (see
https://gitlab.kitware.com/cmake/cmake/-/commit/55196a1440e26917d40e6a7a3eb8d9fb323fa657)
and now finds llvm-ar instead of llvm-lib as CMAKE_AR. This explicitly
specifies CMAKE_AR as llvm-lib so the correct program is found.
