# - Try to find the Portaudio library
#
#  You must provide a PORTAUDIO_ROOT_DIR which contains the header and library
#
#  Once done this will define
#
#  PORTAUDIO_FOUND - system has Portaudio
#  PORTAUDIO_INCLUDE_DIRS - the Portaudio include directory
#  PORTAUDIO_LIBRARY - Link these to use Portaudio
