AES does not have an IV associated with it. IV's (Intial Vectors)
are part of certain modes of using a block cipher. What mode are you using?
Also remember that Crypto++ is a toolkit. It gives you the base
primitives to be put together, and you can then make just about anything you
need. In common cases though it may have a set of primitives tied together
already for doing common tasks.
