These maps are indeed designed for Curse of Strahd. They have all of the secret doors in the correct places with dynamic lighting included. Traps that are large enough to be on the map (you know the ones, no spoilers) are also included. These maps were originally released as an art pack (before add-ons were a thing) if you wanted to do the setup yourself you could use those. The art pack is also available for download. The add-on is not. Here is a link to the original art pack. Castle of the Vampire Art Pack
