# - Try to find Gstreamer and its plugins
# Once done, this will define
#
# GSTREAMER_1_0_FOUND - system has Gstreamer
# GSTREAMER_1_0_INCLUDE_DIRS - the Gstreamer include directories
# GSTREAMER_1_0_LIBRARIES - link these to use Gstreamer
#
# Additionally, gstreamer-base is always looked for and required, and
# the following related variables are defined:
#
# GSTREAMER_1_0_BASE_INCLUDE_DIRS - gstreamer-base's include directory
# GSTREAMER_1_0_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. Currently, the following
# plugins can be searched, and they define the following variables if
# found:
#
# gstreamer-app: GSTREAMER_1_0_APP_INCLUDE_DIRS and GSTREAMER_1_0_APP_LIBRARIES
# gstreamer-audio: GSTREAMER_1_0_AUDIO_INCLUDE_DIRS and GSTREAMER_1_0_AUDIO_LIBRARIES
# gstreamer-fft: GSTREAMER_1_0_FFT_INCLUDE_DIRS and GSTREAMER_1_0_FFT_LIBRARIES
# gstreamer-pbutils: GSTREAMER_1_0_PBUTILS_INCLUDE_DIRS and GSTREAMER_1_0_PBUTILS_LIBRARIES
# gstreamer-video: GSTREAMER_1_0_VIDEO_INCLUDE_DIRS and GSTREAMER_1_0_VIDEO_LIBRARIES
