That is actually a mistake on my part, search-input-file should search
inputs for "include/notmuch.h" and likewise "lib/libnotmuch.so".  The
dirname is important here, since both constants want directories. 
Alternatively, forgoing those constants might be a good idea, but is
not worth investing too much time in.

I think you ought to debug the build and short-circuit the logic by
inferring the version number directly where it is needed.  Without
actual build output that's as much as I can propose.
