This seems related:
CMake just does not know enough about clang-cl and how to invoke it. So far
CMake support for clang-cl requires the VS toolchain.
It probably needs to get a new (set of) files in Modules/Platform or
Modules/Compiler. If such files can be written, you can host them elsewhere
until they are in cmake upstream (and you depend on the version they ship

Indeed. I recommend teaching cmake what you need it to know instead.
