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

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

Start by reproducing the shown `cmake .. -DBUILD_TESTING=ON -DBUILD_COVERAGE=ON` and `make` commands on Ubuntu 22.10 with GCC 12.2.0, then inspect the CMake configuration that adds the coverage flags. Done means the project builds successfully with `BUILD_COVERAGE=ON` using this compiler.
