Hey @marks, you're right it should be added there. It is an old package and is just in maintenance mode so it definitely needs some updating. I'm not the original creator of the bindings but I plan on making a pull sometime in the near future to update it with my changes and instructions for MacOS installation. I will also include the dylibs for MacOS as you suggested.
on MacOS we can use a terminal command called otool to list dependencies, I think on Linux you can use ldd or objdump and windows has dumpbin. Based on the quick google searching I did, I think you can use these to verify what dynamic libs the executable is calling out to. So on Mac I compile my executable and then run the tool to list all the dependencies and then I include the dependencies that are not System libraries guaranteed to be installed. on MacOS the dependencies are libpng16.16.dylib, libjpeg.9.dylib and libtiff.6.dylib. I'm guessing these come from wxWidgets because I didn't have them on a test machine without wxWidgets installed, so I think these might also be the same ones needed on Windows and Linux with the appropriate extensions of course The static variants are also included so it should be possible to statically link with them, though I have not tried that yet
