Conan does a very poor job of managing versions and accidental cycles in your dependency graph. I recall having issues that needed manual patching of conanfiles to bootstrap packages when no prebuilt version existed for the target and it contained itself as a transitive dependency.
Also if you use it, make sure not to rely on Conan center. Their outages can ruin your week.
