openvino: [Bug] Unable to build openvino for ubuntu 18.04, throws no match for ‘operator[]’

• OpenVINO=> 2021.4.752
• Operating System / Platform => Linux Ubuntu 18.04
• Compiler => ❔
• Problem classification => ❔

Detailed description

Previously Openvino used to work with Ubuntu 18.04, but very recently, It has stopped working, I was trying to build openvino for our application but it started failing with some reason. These are the errors which we didn’t see earlier.

While performing make, initially it throwed error “Protobuf compiler not found”, so i went ahead and installed apt-get install protobuf-compiler

Then again it started error Could NOT find Protobuf (missing: Protobuf_INCLUDE_DIR), now this time i installed apt-get install -y libprotobuf-dev

And then now it is throwing error
