managed to get the projects compiling, jpg has been disabled for now and I wasn't able to test the runtime until I can get my hands on the files required by libgldemo

+
+Other information:
+
+   libpng-1.5.11-README.txt
+   libpng-1.5.11-LICENSE.txt
+
+Changes since the last public release (1.5.10):
+  Revised scripts/makefile.darwin: use system zlib; remove quotes around
+    architecture list; add missing ppc architecture; add architecture options
+    to shared library link; don't try to create a shared lib based on missing
+    RELEASE variable.
+  Enable png_set_check_for_invalid_index() for both read and write.
+  Removed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED/#endif in pngpriv.h around
+    declaration of png_handle_unknown().
+  Added -lssp_nonshared in a comment in scripts/makefile.freebsd
+    and changed deprecated NOOBJ and NOPROFILE to NO_OBJ and NO_PROFILE.
+  Revised CMakeLists.txt to not attempt to make a symlink under mingw.
+  Added two images to contrib/pngsuite (1-bit and 2-bit transparent grayscale),
+    and renamed three whose names were inconsistent with those in
+    pngsuite/README.txt.
+  Do not depend upon a GCC feature macro being available for use in generating
+    the linker mapfile symbol prefix.
+  Made fixes for new optimization warnings from gcc 4.7.0. The compiler
+    performed an optimization which is safe but then warned about it.
+    Changing the type of 'palette_number' in pngvalid.c removes the warning.
+  Improved efficiency of new do_check_palette_indexes() function.
+  Don't check palette indexes if num_palette is 0 (as it can be in MNG files).
+  Include zlib.h in contrib/gregbook and contrib/visupng examples.
