#
# ``PulseAudio_FOUND``
# True if the system has the PulseAudio library of at least
# the minimum version specified by either the version parameter
# to find_package() or the variable PulseAudio_MINIMUM_VERSION
# ``PulseAudio_INCLUDE_DIRS``
# The PulseAudio include directory
# ``PulseAudio_LIBRARIES``
# The PulseAudio libraries for linking
# ``PulseAudio_MAINLOOP_LIBRARY``
# The libraries needed to use PulseAudio Mainloop
# ``PulseAudio_VERSION``
# The version of PulseAudio that was found
# ``PulseAudio_INCLUDE_DIR``
# Deprecated, use ``PulseAudio_INCLUDE_DIRS``
# ``PulseAudio_LIBRARY``
# Deprecated, use ``PulseAudio_LIBRARIES``
#
# If ``PulseAudio_FOUND`` is TRUE, it will also define the following
# imported target:
#
# ``PulseAudio::PulseAudio``
# The PulseAudio library
#
# Since 5.41.0.
