+if(NOT KAUTH_BACKEND OR KAUTH_BACKEND STREQUAL "")
+    if (APPLE)
+        set (KAUTH_BACKEND "Apple")
+    elseif (UNIX)

The comparison with the empty string is not necessary, just doing
+if(NOT KAUTH_BACKEND)
should be enough, since an empty string is also evaluated as false.

And maybe I would make KAUTH_BACKEND case-insensitive, so that "Fake", "FAKE" 
and "fake" would be all recognized (do a STRING(TOUPPER ) once).

Looks good otherwise I'd say.
