system_library failing on MacOS

[alexeagle]

With latest bazel_dep(name = "rules_cc", version = "0.1.1") I add to MODULE.bazel:

system_library = use_repo_rule("@rules_cc//cc:system_library.bzl", "system_library")
system_library(
    name = "libmagic",
    hdrs = ["magic.h"],
    static_lib_names = ["libmagic.a"],
    shared_lib_names = ["libmagic.dylib", "libmagic.so"],
    # Look into homebrew specific /lib and /include directories.
    lib_path_hints = ["/opt/homebrew/lib"], 
    includes = ["/opt/homebrew/include"]
)

But it fails to build:

alexeagle@aspect-build bazel105 % find $(brew --prefix) -name magic.h
/opt/homebrew/include/magic.h
/opt/homebrew/Cellar/libmagic/5.46/include/magic.h
