		2		# FindPipeWire
		3		# -------
		4		#
		5		# Try to find PipeWire on a Unix system.
		6		#
		7		# This will define the following variables:
		8		#
		9		# ``PipeWire_FOUND``
		10		# True if (the requested version of) PipeWire is available
		11		# ``PipeWire_VERSION``
		12		# The version of PipeWire
		13		# ``PipeWire_LIBRARIES``
		14		# This can be passed to target_link_libraries() instead of the ``PipeWire::PipeWire``
		15		# target
		16		# ``PipeWire_INCLUDE_DIRS``
		17		# This should be passed to target_include_directories() if the target is not
		18		# used for linking
		19		# ``PipeWire_DEFINITIONS``
		20		# This should be passed to target_compile_options() if the target is not
		21		# used for linking
		22		#
		23		# If ``PipeWire_FOUND`` is TRUE, it will also define the following imported target:
		24		#
		25		# ``PipeWire::PipeWire``
		26		# The PipeWire library
		27		#
		28		# In general we recommend using the imported target, as it is easier to use.
		29		# Bear in mind, however, that if the target is in the link interface of an
		30		# exported library, it must be made available by the package config file.
