   2 #  The OpenCV CMake configuration file
   3 #
   4 #             ** File generated automatically, do not modify **
   5 #
   6 #  Usage from an external project:
   7 #    In your CMakeLists.txt, add these lines:
   8 #
   9 #    FIND_PACKAGE(OpenCV REQUIRED)
  10 #    TARGET_LINK_LIBRARIES(MY_TARGET_NAME ${OpenCV_LIBS})
  11 #
  12 #    Or you can search for specific OpenCV modules:
  13 #
  14 #    FIND_PACKAGE(OpenCV REQUIRED core highgui)
  15 #
  16 #    If the module is found then OPENCV_<MODULE>_FOUND is set to TRUE.
  17 #
  18 #    This file will define the following variables:
  19 #      - OpenCV_LIBS                     : The list of libraries to links against.
  20 #      - OpenCV_LIB_DIR                  : The directory(es) where lib files are. Calling LINK_DIRECTORIES
  21 #                                          with this path is NOT needed.
  22 #      - OpenCV_INCLUDE_DIRS             : The OpenCV include directories.
  23 #      - OpenCV_COMPUTE_CAPABILITIES     : The version of compute capability
  24 #      - OpenCV_ANDROID_NATIVE_API_LEVEL : Minimum required level of Android API
  25 #      - OpenCV_VERSION                  : The version of this OpenCV build. Example: "2.4.0"
  26 #      - OpenCV_VERSION_MAJOR            : Major version part of OpenCV_VERSION. Example: "2"
  27 #      - OpenCV_VERSION_MINOR            : Minor version part of OpenCV_VERSION. Example: "4"
  28 #      - OpenCV_VERSION_PATCH            : Patch version part of OpenCV_VERSION. Example: "0"
  29 #
  30 #    Advanced variables:
  31 #      - OpenCV_SHARED
  32 #      - OpenCV_CONFIG_PATH
  33 #      - OpenCV_LIB_COMPONENTS
