# FindPulseAudio
# --------------
# Finds the PulseAudio library
#
# This will define the following variables::
#
# PULSEAUDIO_FOUND - system has the PulseAudio library
# PULSEAUDIO_INCLUDE_DIRS - the PulseAudio include directory
# PULSEAUDIO_LIBRARIES - the libraries needed to use PulseAudio
# PULSEAUDIO_DEFINITIONS - the definitions needed to use PulseAudio
#
# and the following imported targets::
#
# PulseAudio::PulseAudio - The PulseAudio library
