Comment (by kencu):

 help me understand better please, I think this was different.

 Jeremy wrote this in an unusual way, with backtiks in the the cmake
 configure line to drive pkg-config for the ffi flags.

 without pkg-config, there was always a warning right after the cmake
 config line that pkg-config was not found, but never an error. Ryan opened
 a ticket about it.

 so I think the backtik line just produced an empty string for the ffi
 includes when pkg-config was not found, but it never actually errored. But
 it is used to generate the proper includes if it is found ( the warning is
 gone when pkgconfig is added).
