# - Try to find libopendsp
# Once done this will define
#
# DSP_FOUND - system has libopendsp
# DSP_INCLUDE_DIRS - the libopendsp include directories
# DSP_LIBRARIES - Link these to use libopendsp
# DSP_DEFINITIONS - Compiler switches required for using libopendsp
#
# DSP_HAS_DSP_VERSION - defined when libopendsp has dsp_get_version()
