Most likely, your library doesn't export and interfaces of libpng, thus
  set_target_properties(mylibrary PROPERTIES
     IMPORTED_LOCATION "${mylibrary_location}"
     IMPORTED_LINK_DEPENDENT_LIBRARIES "png;z"
     IMPORTED_LINK_INTERFACE_LIBRARIES ""
 )

This assumes that mylibrary is a shared library.
