From 07e7b727b7df7fc5bf0e1f296ba136e0653202ea Mon Sep 17 00:00:00 2001

Subject: [PATCH] change library linking order
Since -lraspidmxPng requires the png library (libpng), re-arrange the order of
linking so that it succeeds. Otherwise I get errors like the following:
undefined reference to `png_create_write_struct'
...as well as undefined references to various other libpng objects.
Upstream-status: submitted [https://github.com/AndrewFromMelbourne/raspidmx/pull/29]
