This recipe template supports different features:

• CARGO_PROFILE_RELEASE_STRIP=symbols in order to reduce the size of the package by removing unnecessary symbols.
• CARGO_PROFILE_RELEASE_LTO=fat in order to optimize the binary for better performance.
• cargo auditable install in order to ensure the package is auditable.
• Bundle licenses of statically linked libraries.
• Use --no-track to not create $PREFIX/.crates.toml and $PREFIX/.crates2.json.
