				# - If UPnP is enabled USE_UPNP must be defined
				# - If UPnP should be the default port map method, USE_UPNP should be
				# defined to 1, otherwise it should be defined to 0.
				#
				# What we need is some tristate value:
				# - /* #undef USE_UPNP */ if UPnP is disabled
				# - #define USE_UPNP 0 if UPnP is enabled but not the default method
				# - #define USE_UPNP 1 if UPnP is enabled and is the default method
				#
				# CMake cannot differentiate between a 0 value and the #undef case when
				# using the configure_file function.
				# To workaround this limitation, the #define 0 case is set to a value
				# which is not interpreted as false by CMake but will be casted to
				# boolean as false in the code.
