   7 # The following variables are optionally searched for defaults
   8 #  OpenCV_DIR:            Base directory of OpenCv tree to use.
   9 #
  10 ## 2: Variable
  11 # The following are set after configuration is done:
  12 #
  13 #  OpenCV_FOUND
  14 #  OpenCV_LIBS
  15 #  OpenCV_INCLUDE_DIR
  16 #  OpenCV_VERSION (OpenCV_VERSION_MAJOR, OpenCV_VERSION_MINOR, OpenCV_VERSION_PATCH)
