I think you want to be using a mutli-FROM dockerfile here, otherwise
you're including all the intermediate build artefacts in the final image.

See debian/buster-gcc-ibt.dockerfile for an example.

That said, I'm not sure we want to be making custom containers for every
minor tweak we have on a build environment.  What's wrong with just
putting CPPCHECK in the normal container?
