Subject: Makefile: Add library version information on OS X.
X-Git-Tag: 0.2~47
X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=72ea1b71c6b65965e3b205271d51c66ff66e13bf;ds=sidebyside

Makefile: Add library version information on OS X.

This encodes the library version into the library, where the linking
binary can pick it up, and the linker can even enforce mismatches in
the minor release, (such as linking a binary against version 1.2 and
then attempting to run it against version 1.1).
