Description
Hello,
After following the instructions for compiling the C++ code in Docker, I get the following Bazel error:
`$ docker build -t qcc4cp:latest .
DEPRECATED: The legacy builder is deprecated and will be removed in a future release.

I get the exact same error when running the compilation outside of Docker following README.Linux.md. I am on Ubuntu 22.04.
I am not a Bazel user and Google so far didn't help.
