onnxoptimizer vendors onnx and protobuf as git submodules and links both statically; protobuf (BSD-3-Clause) pulls in abseil-cpp (Apache-2.0) the same way onnx’s own standalone build does (see docs/packages/onnx.yaml). Abseil ships no NOTICE file to propagate, and both onnxoptimizer and abseil are Apache-2.0, so the wheel’s own LICENSE already covers it.
