everest-playground cmake failure - missing libpcap

[DanLipsitt]

I am trying to use docker/everest-playground/.devcontainer.json in VSCode. After launching the docker container and sourcing init.sh, cmake fails saying No package 'libcap' found. I verified that libpcap-dev is installed in the devcontainer.

Error log:
