		31		#
		32		# This module finds an installed SIP. It sets the following variables:
		33		#
		34		# ::
		35		#
		36		# SIP_FOUND - set to true if SIP is found
		37		# SIP_DIR - the directory where SIP is installed
		38		# SIP_EXECUTABLE - the path to the SIP executable
		39		# SIP_INCLUDE_DIRS - Where to find sip.h.
		40		# SIP_VERSION - the version number of the SIP executable
		41		#
		42		#
		43		#
		44		# The minimum required version of SIP can be specified using the
		45		# standard syntax, e.g. find_package(SIP 4.19)
		46		#
		47		# All information is collected from the SIP_EXECUTABLE so the version
		48		# to be found can be changed from the command line by means of setting
		49		# SIP_EXECUTABLE
