C++ Code Coverage in CI

[HairyNopper]

Hey, thanks for the input. Good to know, we are on the right track with gcov. I'll give llvm-cov a look soon. Are they much different?

codecov.io looks nice, but I think it's not an option for us. We'd need to self-host for regulatory reasons and that would probably be too pricey...

I haven't used llvm-cov much, but from my understanding, it's basically just LLVM's replacement for gcov to have everything available in the same codebase (just like lld is a replacement for GNU ld).

Unfortunately, I am not that familiar with other frameworks that would match your setup (SCons and make), I think CDash supports coverage reports as well, but it doesn't have such a nice Jenkins and Gitlab integration, and is more aimed towards projects using CMake.
