Description
Env:
I'm running OL8 docker on Apple Silicon and trying to build a C++ repo on it. There is a third-party which is being built using below cmake
While using the load("@rules_foreign_cc//foreign_cc:defs.bzl", "cmake") I get below errors . Looking at the docs ideally it should be work right ?

Contributor guide
Research direction
Reproduce the OL8 Docker-on-Apple-Silicon build using load("@rules_foreign_cc//foreign_cc:defs.bzl", "cmake") and inspect third-party/rules_libevent/BUILD:26:6. Trace toolchain resolution for @@rules_foreign_cc~//toolchains:ninja_toolchain, using --toolchain_resolution_debug with that toolchain type; done means the CMake target resolves a matching Ninja toolchain on arm64.
