No. png/CMakeLists.txt is not updated. so the new source fles are not built.

@cstkingkey Sorry, I had forgotten about CMake-based building. That should be better with the commit mentionned above. Could you, please, explain a bit what are the connections between projects FLTK and Godot, if any ? TIA.
