compiling mmdeploy-runtime

[laurentbsp]

Hello,

I am trying to recompile mmdeploy-runtime to make a custom pip package with a small change (limit multithreading during ONNX inference). I have followed the instructions here:
https://mmdeploy.readthedocs.io/en/latest/01-how-to-build/build_from_source.html
https://mmdeploy.readthedocs.io/en/latest/01-how-to-build/linux-x86_64.html
https://github.com/open-mmlab/mmdeploy/tree/main/tools/package_tools

python tools/package_tools/generate_build_config.py --backend 'ort' \
          --system linux --build-mmdeploy --device cpu --build-sdk \
          --build-sdk-monolithic --build-sdk-python --sdk-dynamic-net \
          --output config.yml
python tools/package_tools/mmdeploy_builder.py --config config.yml --output-dir pack

It completes successfully and creates a pip package that I can install. However, when to import mmdeploy_runtime I get an error about missing a opencv library. This can be resolved by adding the adding the OpenCV lib path to LD_LIBRARY_PATH, but I am trying to build a self-contained package. The one I download using pip install mmdeploy-runtime appears to have all the dependencies built into libmmdeploy.so.1, which is ~40MB whereas the one I build is ~4MB. I have tried a few things but cannot figure out what I am doing wrong/differently on how you build your pip package.

Thanks for your help!
