There might be situations where the same dependency comes up multiple times which leads to a cycle in the detection.
That might be due to a cyclic dependency or just some "unfortunate" structure between packages.
Remove the recursive call leading to a possible error and maintain a set of packages checked already to avoid checking any multiple times. This makes sure the function terminates eventually.
