# Module for finding the core components of OpenCV installed by
# graphics/opencv-core.  Use for projects that require only
# opencv_core or opencv_imgproc.  Others should use the
# standard OpenCV CMake find routines provided by graphics/opencv.
#
# This module provides:
# OPENCVCORE_FOUND - defined if the required OpenCV components are found
# OpenCV_INCLUDE_DIRS - the path to the OpenCV headers
# OpenCV_LIBS - the OpenCV libraries to link to
# OpenCV_VERSION - the version of OpenCV
#
# Example usage: find_package( OpenCVCore COMPONENTS core imgproc REQUIRED )
