# - Try to find GStreamer and its plugins # Once done, this will define # # GSTREAMER_FOUND - system has GStreamer # GSTREAMER_INCLUDE_DIRS - the GStreamer include directories # GSTREAMER_LIBRARIES - link these to use GStreamer # # Additionally, gstreamer-base is always looked for and required, and # the following related variables are defined: # # GSTREAMER_BASE_INCLUDE_DIRS - gstreamer-base's include directory # GSTREAMER_BASE_LIBRARIES - link to these to use gstreamer-base # # Optionally, the COMPONENTS keyword can be passed to find_package() # and GStreamer plugins can be looked for.
