ACT-CV depends on cffi. It's not an ACT-R issue

from the docs (http://act-cv.sourceforge.net/docs/)

> ACT-CV depends on the CFFI package, which is available for all major
> Lisps. This way, ACT-CV is not bound to a single flavor of Lisp. After

The ACT-CV windows installer already contains cffi. If you want to use
that with your personal Lisp of choice, you have to include the path to
cffi in your ASDF registry. This may help:

If you're working from the sources, get CFFI here:
