Cycling a tank is the establishment of aerobic bacteria to break down wastes in the tank. Adding inanimate material, such as base rock, decorations, equipment, etc do not affect that process unless the materials have something in them to kill off that filtration. Any aquarium safe products that have been rinsed in RO or distilled water will not do that, including the Caribsea rocks.
Adding live rock to an established system won't even send the system into a cycle. When you add dead animal tissues to an aquarium, such as dead fish or inverts, uneaten food, or live rock that has not been fully cured, the rotting process releases ammonia. The biological colonies in the tank break that down. The biological colonies in a tank build themselves up to match the amount of waste being produced. That's why you can't add too many fish at once. Therefore, if you add a bunch of LR at once to a system that is not cured, the die off from the rock overwhelmes the biological colony of the tank and causes an ammonia spike. Nonetheless, this is NOT a cycle, but simply an ammonia excess caused by overwhelmed biological filtration.
Curing live rock is the process of adding it to a separate container that allows two things to happen. First, the container contains saltwater allowing what is alive on the rock to remain that way, alive. Secondly, it allows the dead matter on the rock that occured during handling and shipment to rot off. That way, when you transfer it to a new system, the LR has had it's dead matter removed so it doesn't load down the biological filtration. Since the Caribsea reef rock is not live by any means, it does not need to be cured.
Sorry if I am explaining things you already know, I just wanted to answer your question as completely as possible.
