# ===================================================================================
#  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)
#    include_directories(${OpenCV_INCLUDE_DIRS})
#    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 all imported targets for OpenCV modules.
#      - 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: "@OPENCV_VERSION_PLAIN@"
#      - OpenCV_VERSION_MAJOR            : Major version part of OpenCV_VERSION: "@OPENCV_VERSION_MAJOR@"
#      - OpenCV_VERSION_MINOR            : Minor version part of OpenCV_VERSION: "@OPENCV_VERSION_MINOR@"
#      - OpenCV_VERSION_PATCH            : Patch version part of OpenCV_VERSION: "@OPENCV_VERSION_PATCH@"
#      - OpenCV_VERSION_STATUS           : Development status of this build: "@OPENCV_VERSION_STATUS@"
#
#    Advanced variables:
#      - OpenCV_SHARED                   : Use OpenCV as shared library
#      - OpenCV_CONFIG_PATH              : Path to this OpenCVConfig.cmake
#      - OpenCV_INSTALL_PATH             : OpenCV location (not set on Windows)
#      - OpenCV_LIB_COMPONENTS           : Present OpenCV modules list
#      - OpenCV_USE_MANGLED_PATHS        : Mangled OpenCV path flag
#      - OpenCV_MODULES_SUFFIX           : The suffix for OpenCVModules-XXX.cmake file
#      - OpenCV_HAVE_ANDROID_CAMERA      : Presence of Android native camera wrappers
#
#    Deprecated variables:
#      - OpenCV_VERSION_TWEAK            : Always "0"
