Usage: build-setup-pkg.command --nodtool PATH --translator PATH --cmake-root DIR --ninja PATH --output PKG [options]

Creates a game-code-free WiiCompiled Setup.pkg. The supplied tools must be
maintainer-verified, redistributable macOS arm64 artifacts. The resulting pkg
is unsigned unless --installer-identity is supplied; releases should sign and
notarize it with a Developer ID Installer certificate.
