@pornel For the autotools part, you want to use the standard pkg-config macros: https://www.flameeyes.eu/autotools-mythbuster/pkgconfig/pkg_check_modules.html For cmake... whatever it uses for pkg-config. |

This is implementation that adds support for reading PNG in cjpeg. All PNG variants are supported with caveats: alpha channel is stripped, 48bit is converted to 24bit, color profiles are ignored.
However, I'm not touching autotools with a 10-foot pole, so I haven't done anything to link with libpng and define
PNG_SUPPORTED.Can somebody else add the libpng detection part?
