I appended a pre-built framework version of the latest libpng (1.6.40). It works with macOS 10.13 and later. I have built it with these steps:

   a Download source code from http://libpng.org/pub/png/libpng.html
   b Go to the source directory and build an Xcode project:
        cmake -G Xcode . -DPNG_FRAMEWORK=ON -DPNG_HARDWARE_OPTIMIZATIONS=OFF
   c Open the Xcode project and select "libpng" in left side bar
   d Select "Targets > png_framework" in middle sector
   e Set "Architectures" to "Standard Architectures (Apple Silicon, Intel)"
   f Set "Build Active Architecture Only" to "No"
   g Set "macOS Deployment Target" to "macOS 10.13" or oldest available
   h Set "Framework Version" to "A"
   i Set "Compatibility Version" to "1.0.0"
   j Set "Current Library Version" to the actual version of libpng
   k Select "png_framework > Any Mac" in title bar and go to "Edit Scheme ..."
   l Set "Build Configuration" to "Release"
   m Select "Product > Build" from the menu bar
   n Using Terminal go to bundle directory, change loader path and sign code:
        install_name_tool -change /opt/local/lib/libz.1.dylib /usr/lib/libz.1.dylib png
        codesign --force -s - png
   o Copy the framework to /Library/Frameworks and make sure no other versions
     of libpng are installed (if applicable remove macports version of libpng)
