Here are the locations of "opencv" in /usr/include

johnvorwald@johnvorwald-desktop:~/MYNT-EYE-S-SDK$ find /usr/include -name pencv -print
/usr/include/boost/compute/interop/opencv.hpp
/usr/include/boost/compute/interop/opencv
/usr/include/opencv4
/usr/include/opencv4/opencv2
/usr/include/opencv4/opencv2/opencv_modules.hpp
/usr/include/opencv4/opencv2/opencv.hpp
/usr/include/opencv4/opencv2/gapi/opencv_includes.hpp

How should I fix this?
