I'd like a sanity check!
Waybar has a dependency on a C++ logging library called spdlog. This project depends on fmt and by default uses an included copy. I've raised a ticket about removing this but it doesn't look like the developer is interested .
In this case, I feel it expedient to patch out the logic to use the bundled headers  and outright remove the directories . Am I correct in this conclusion or is this too far-reaching?
