FindPulseAudio
--------------
Try to locate the PulseAudio library.
If found, this will define the following variables:
``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.
