# Description:
# Try to find libDC1394 for IEEE1394 camera. First search for libdc1394-2.x
# and if not found, search for libdc1394-1.x
# Once run this will define:
#
# DC1394_FOUND
# DC1394_INCLUDE_DIRS
# DC1394_LIBRARIES
# DC1394_VERSION
#
# The two defines below are only useful to compile with libdc1394-2.x. In
# that case DC1394_VERSION=2. Since the libdc1394-2.x API is not stable, we
# need to determine if dc1394_find_cameras() or dc1394_enumerate_cameras()
# functions are available. dc1394_enumerate_cameras() was introduced after
# libdc1394-2.0.0-rc7. DC1394_CAMERA_ENUMERATE_FOUND is TRUE when
# dc1394_camera_enumerate() function is found. DC1394_FIND_CAMERAS_FOUND is
# TRUE when dc1394_find_cameras() is found.
# DC1394_CAMERA_ENUMERATE_FOUND
# DC1394_FIND_CAMERAS_FOUND
