BUILD_COVERAGE doesn't work out-of-the box on Ubuntu 22.10 with gcc 12.2.0

[Overflwn]

I'm running Ubuntu 22.10 with qt6-base and libspdlog-dev installed, running cmake .. -DBUILD_TESTING=ON -DBUILD_COVERAGE=ON runs fine, but running make afterwards (gcc version 12.2.0 (Ubuntu 12.2.0-3ubuntu1) ) returns

I haven't built it with gcc. Actually, I'm not sure if I will consider supporting gcc. Probably will update the readme to let the devs know that they should use clang (at least until I consider adapting to gcc).

You're right. Using clang works just fine. I think gcc supports code coverage flags too, they're just called differently.
