I don't feel this is appropriate.  If someone cherry picked plugins
for release then could end up with problems if they didn't copy across
png as well even though it shouldn't be needed.

With CMake you can run build tests to test if certain capabilities
work or not and then toggle settings accordingly, perhaps this might
be useful on the FreeType front.  If not then have a CMake option for
the FreeType where you can add additional libraries or toggle on the
requirement for linking to PNG.  The later is the route I'd suggest
for now.

Robert.
