Robert, it occurs to me that you could just do a find_library for PNG and
then, if found, add the PNG lib to the freetype plugin libraries, even if
freetype didn't actually depend on PNG. Maybe that isn't super rigorous but
linking in a library that isn't needed should be harmless. This simpler task
I can do for the freetype plugin CMakeLists.txt file if you want.
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.

Good points, Robert. I'm not the one to do this fancier CMake setup.
