opencv2 on ubuntu

openCV 버전이 2.x대로 오르면서 경로가 변했는지
이전에 내가 정리했던 내용이 전부 무효가 되었다 ㅠㅠ

include 경로 <opencv/cv.h> 에서 <opencv2/opencv.hpp> 로 변경
/usr/include/opencv2

그리고 링커 옵션도 변경되었다. (라이브러리 이름도 바뀐듯)

-lopencv_core << 기존의 -lcv -lopencv_imgproc -lopencv_highgui  << 기존의 -lhighgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_legacy -lopencv_flann -lopencv_nonfree

솔찍히 가장 큰 차이점은..
c가 아니라 c++로 바뀌면서
gcc 대신 g++로 써야 한다는 점이려나? ㅋㅋ

아무튼 설치 시에는 libopencv-dev 패키지로 설치한다.
