Ryan Davis seems to have plans to write such a bindings package as
well, and he has some prototype code over here:
<http://github.com/ryepup/cl-opencv>. Perhaps you should get in touch
with him.

I personally prefer to write the FFI definitions as I go along, but
this is not always practical if the library is too big and/or changes
very often.

CFFI's User Manual has a nice tutorial and its reference chapters also
have a bunch of small examples. cl-opengl, iolib, and osicat are some
libraries that use CFFI.

Hope that helps,
