Missing submodules - Not able to compile

[CarloAmbrogi]

In https://github.com/snes9xgit/snes9x/tree/c3fa4009a3ce9724d8d5dc7646b1eed20f91234b/win32/libpng -> src @ b78804f and in https://github.com/rileytestut/N64DeltaCore/tree/e598f512b498e1b639a8d2134113169f4b8d0d26/Mupen64Plus -> libpng @ 8439534 there are two non-clickable (missing) submodules! Please fix so that I can compile the app!

These are not clickable in Github as this git repository is hosted on a non-Github server.

The libpng git repo referred by both of these is at: git.code.sf.net/p/libpng/code The source files can be downloaded separately here: http://www.libpng.org/pub/png/libpng.html (but doing it this way would require you to manually find the right commit hashes)

The intended way to clone the repo is to use git submodule update --init --recursive after cloning the repo (step 2 here), which automatically will check out the code from these submodules. Github has more info on submodules here.
