The patch which removes the CPack-generated spec
and adds a proper spec for client, server and library
was done by Dmitry Simonenko.

Hand-port the patch to the master, since it's gone too
far away from the origin and merging it ends up in a mess.

Minor tweaks of the code as per a more thorough review of the 10k
patch which introduces C++ instead of Objective C.
No bugs found or fixed, only style changes.
