Sorry for my poor on CMake. I follow the instruction on README.md and install all dependencies, but still got this errors. Could you please give me some advice, thanks a lot!

Which OS are you using?

Which OS are you using?
Ubuntu 18.04. This issue has been solved, but this issue still confused me.

I build a image by Dockerfile, and it work on x86 architecture (should change default python to python3 in Dockerfile line 252, otherwise it will meet error when installing opencv-python), but for arm architecture (nvidia jetson nx), maybe it should change some command in Dockfile, such as change the version of openvino to arm version, and so on. So could you please give me some advice if i want to build a image on arm architecture.

It would be better if there are some documents about this project, and descriptions for each module. Thanks a lot!
