    Description

      According to https://doc.qt.io/qt-5/qtgui-attribution-libpng.html, configure takes the options "-system-png" and "-no-png". According to the general advise on the "remaining features" printed by "configure --help", one ought to say either "-libpng=no" or "-no-libpng".

      On my system, neither "-no-png" nor "-libpng=no" works. Fortunately, "-no-libpng"  does work. I have not tried "-system-png" .
