# ===================================================================================
#  The OpenCV CMake configuration file
#
#             ** File generated automatically, do not modify **
#
#  Usage from an external project:
#    In your CMakeLists.txt, add these lines:
#
#    FIND_PACKAGE(OpenCV REQUIRED)
#    TARGET_LINK_LIBRARIES(MY_TARGET_NAME ${OpenCV_LIBS})
#
#    Or you can search for specific OpenCV modules:
#
#    FIND_PACKAGE(OpenCV REQUIRED core highgui)
#
#    If the module is found then OPENCV_<MODULE>_FOUND is set to TRUE.
#
#    This file will define the following variables:
#      - OpenCV_LIBS                     : The list of libraries to links against.
#      - OpenCV_LIB_DIR                  : The directory(es) where lib files are. Calling LINK_DIRECTORIES
#                                          with this path is NOT needed.
#      - OpenCV_INCLUDE_DIRS             : The OpenCV include directories.
#      - OpenCV_COMPUTE_CAPABILITIES     : The version of compute capability
#      - OpenCV_ANDROID_NATIVE_API_LEVEL : Minimum required level of Android API
#      - OpenCV_VERSION                  : The version of this OpenCV build. Example: "@OPENCV_VERSION@"
#      - OpenCV_VERSION_MAJOR            : Major version part of OpenCV_VERSION. Example: "@OPENCV_VERSION_MAJOR@"
#      - OpenCV_VERSION_MINOR            : Minor version part of OpenCV_VERSION. Example: "@OPENCV_VERSION_MINOR@"
#      - OpenCV_VERSION_PATCH            : Patch version part of OpenCV_VERSION. Example: "@OPENCV_VERSION_PATCH@"
#
#    Advanced variables:
#      - OpenCV_SHARED
#      - OpenCV_CONFIG_PATH
#      - OpenCV_INSTALL_PATH  (not set on Windows)
#      - OpenCV_LIB_COMPONENTS
#      - OpenCV_USE_MANGLED_PATHS
