# cmake-format: off
# .rst: FindPipeWire
# -------
#
# Try to find PipeWire on a Unix system.
#
# This will define the following variables:
#
# ``PIPEWIRE_FOUND`` True if (the requested version of) PipeWire is available
# ``PIPEWIRE_VERSION`` The version of PipeWire ``PIPEWIRE_LIBRARIES`` This can
# be passed to target_link_libraries() instead of the ``PipeWire::PipeWire``
# target ``PIPEWIRE_INCLUDE_DIRS`` This should be passed to
# target_include_directories() if the target is not used for linking
# ``PIPEWIRE_COMPILE_FLAGS`` This should be passed to target_compile_options()
# if the target is not used for linking
#
# If ``PIPEWIRE_FOUND`` is TRUE, it will also define the following imported
# target:
#
# ``PipeWire::PipeWire`` The PipeWire library
#
# In general we recommend using the imported target, as it is easier to use.
# Bear in mind, however, that if the target is in the link interface of an
# exported library, it must be made available by the package config file.
