libffi shared library name

[Zulu-Inuoe]

When loading cl-autowrap/libffi, I get an error about not being able to open the shared library "libffi"

Latest libffi by default will build out as libffi-6

If you see CFFI's libffi loading, their form looks like this:

(define-foreign-library (libffi)
  (:darwin (:or "libffi.dylib" "libffi32.dylib" "/usr/lib/libffi.dylib"))
  (:solaris (:or "/usr/lib/amd64/libffi.so" "/usr/lib/libffi.so"))
  (:openbsd "libffi.so")
  (:unix (:or "libffi.so.6" "libffi32.so.6" "libffi.so.5" "libffi32.so.5"))
  (:windows (:or "libffi-6.dll" "libffi-5.dll" "libffi.dll"))
  (t (:default "libffi")))

(see here)

Autowrap's looks like this:

(cffi:define-foreign-library libffi
  (:darwin (:or (:framework "libffi") (:default "libffi")))
  (:unix "libffi.so")
  (:windows "libffi.dll")
  (t (:default "libffi")))

(cffi:use-foreign-library libffi)

I think autowrap should use the same form CFFI does, for completeness
