These can be quite big so lets cache them. I couldn't find any nots on
ccache in the gitlab docs so I've just ignored it for now.

There's no built-in support for ccache, but you can enable it
reasonably easily.

In libvirt we add "ccache" to the dockerfile as a package to
be installed in the container image.

Then in the dockerfile again we add

  mkdir -p /usr/libexec/ccache-wrappers
  ln -s /usr/bin/ccache /usr/libexec/ccache-wrappers/cc
  ln -s /usr/bin/ccache /usr/libexec/ccache-wrappers/$(basename /usr/bin/gcc)
  export CCACHE_WRAPPERSDIR=/usr/libexec/ccache-wrappers

And in .gitlab-ci.yml, in each job we set

  before_script:
    export CCACHE_BASEDIR="$(pwd)
    export CCACHE_DIR="$CCACHE_BASEDIR/ccache"
    export CCACHE_MAXSIZE="500M"
    export PATH="$CCACHE_WRAPPERSDIR:$PATH"
  cache:
    paths:
      - ccache/
    key: "$CI_JOB_NAME"

Regards,
Daniel
