Ah, I wasn't aware of that. In that case then I can update this to use a local
variable instead of messing with the CMake variable itself.
Though I do also have a question. If CMake no longer computer this value and
we're not computing it ourselves, is this now Clang's responsibility? The CMake
4 release notes note that `Instead, compilers are expected to choose a default
macOS SDK on their own` so I guess it is?
Either way, we can get the path we need from `xcrun` as you said.
