While building with PKG_CONFIG_PATH=$(brew --prefix icu4c)/lib/pkgconfig cargo install --path . -F external-harfbuzz in cloned git repo, has following error:

When use ls -la /opt/homebrew/Cellar/harfbuzz/11.1.0/include/harfbuzz | grep hb.h does has a hb.h shows up.

System: MacOS aarch64 C/C++ tool chain: Macos original Rust: newest stable

If build without -F external-harfbuzz would works fine. Wondering the correct way to build with feautures mentioned in the docs at git HEAD?
