The full way to write it would be:

png = not_found
if get_option('png').allowed() and have_system
  png = dependency('libpng', required: get_option('png'),
                   method: 'pkg-config', kwargs: static_kwargs)
endif

but we can now also use

png = dependency('libpng',
                 required: get_option('png').disable_auto_if(not have_system),
                 method: 'pkg-config', kwargs: static_kwargs)

Use the one that you prefer.
