Wyoming dependancies for ARMv6 (Raspberry Pi 0)

Build:

OnnxRuntime (Wyoming Satellite

• Use a docker container for the target system so you can build natively
  • docker build --platform linux/arm/v6 -t onnxbuild -f Dockerfile .
  • docker run --platform linux/arm/v6 --rm -v /home/james/docker/ccache:/ccache -v /home/james/docker/runtime:/runtime -it onnxbuild bash
    • CCache is critical for your own sanity
  • Build CMake from source (3.30.2 used), as the generally available ones aren't working with onnx at the time of writing
  • Install numpy (< version 2.0 for the sepcified onnx version)
  • ./build.sh ${BUILDARGS} --update --build --build_shared_lib --enable_pybind --build_wheel --parallel --compile_no_warning_as_error
    • Note, after v1.16.3, onnx runetime wasn't building for the archtecture.

TF Lite (Wyoming OpenWakeWord)

• Use a docker container for the target system (same way as before)
  • ./tensorflow/lite/tools/pip_package/build_pip_package_with_cmake.sh native
  • You'll need to pre-load libatomic on execution (or you can statically link in the build system)

I'm sure I'm missing some small things, such as needing to grab/copy some files, but they'll be few.

Wyoming OpenWakeWord is "working" for me, but the performance is making it completely unusable. See my open issue
