title: Gitlab CI runner
body: <p>I have used <a href="https://gitlab.com/gitlab-org/gitlab-ci-multi-runner/blob/master/docs/install/docker.md" rel="nofollow noreferrer">this tutorial</a> for setting up a gitlab ci runner. The runner seems to be working. Now I want to build a C++ project with it.</p>
  
  <p>How can I do this? </p>
