in repository irssi-plugin-otr.

commit c21af79837560ce02ecb79ac3888be2c672847a3
Author: Uli Meis <a.sporto+bee at gmail.com>
Date:   Fri Jun 6 00:55:28 2008 +0200

    Support for cmake < 2.4.7.
    
    Earlier versions don't have FindPkgConfig.cmake so it will now be pulled from
    cmake.org automatically if not present. Don't ask me how far back it goes now
    but at least what debian seems to call "cmake 2.4-patch 5" works.
