# - Find alsa
# Find the alsa libraries (asound)
#
#  This module defines the following variables:
#     ALSA_FOUND       - True if ALSA_INCLUDE_DIR & ALSA_LIBRARY are found
#     ALSA_LIBRARIES   - Set when ALSA_LIBRARY is found
#     ALSA_INCLUDE_DIRS - Set when ALSA_INCLUDE_DIR is found
#
#     ALSA_INCLUDE_DIR - where to find asoundlib.h, etc.
#     ALSA_LIBRARY     - the asound library
#     ALSA_VERSION_STRING - the version of alsa found (since CMake 2.8.8)
