34 unresolved external symbol_png errors

[Elfin Jedi]

I am trying to build Angband with Visual Studio in hopes of creating my own variant, but I am not a coder only a mod merger maker. I followed the instructions in the visual studio step by step file as best I could, but I am getting 34 errors. They are all unresolved external symbol errors involving pngs. I don't know what to do about them.
