I am trying to compile a project that uses both the Qt framework and libpng. I had errors with the previous version of libpng, so I downloaded a new code base and now I get the following errors when trying to create my project:

I suspect that there is a version issue between the included libpng sources and the compiled mingw, but I cannot say. What am I doing wrong?
