Additionally, consider implementing this as an "module" (like bugprone), simply implement factory that would look into config options that start with "custom-" and then parse options like: Source, Message, Language, and based on that construct checks, gain is that dependency on clang-query could be turn on/off in cmake file, and it could only result in registering or not that module. Also extending that functionality would be easier with things like TraverseMode and so on...
