Find Advanced Linux Sound Architecture (ALSA)

Find the alsa libraries (``asound``)

IMPORTED Targets
^^^^^^^^^^^^^^^^

This module defines :prop_tgt:`IMPORTED` target ``ALSA::ALSA``, if
ALSA has been found.

Result Variables
^^^^^^^^^^^^^^^^

This module defines the following variables:

``ALSA_FOUND``
  True if ALSA_INCLUDE_DIR & ALSA_LIBRARY are found

``ALSA_LIBRARIES``
  List of libraries when using ALSA.

``ALSA_INCLUDE_DIRS``
  Where to find the ALSA headers.

Cache variables
^^^^^^^^^^^^^^^

The following cache variables may also be set:

``ALSA_INCLUDE_DIR``
  the ALSA include directory

``ALSA_LIBRARY``
  the absolute path of the asound library
#]=======================================================================]

find_path(ALSA_INCLUDE_DIR NAMES alsa/asoundlib.h

)
