Hi,

output of "pkg-config --cflags --libs libopencv" is following:

Changes from opencv 2.3, opencv.pc format has been changed.
Opencv2.4 came to include the path to the library and does not use -l and -L.

opencv2.3:
---
Name: OpenCV
Description: Open Source Computer Vision Library
Version: 2.3.1
Libs: -L${libdir} -lopencv_core -lopencv_imgproc -lopencv_highgui
-lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d
-lopencv_objdetect -lopencv_contrib -lopencv_legacy -lopencv_flann
Cflags: -I${includedir_old} -I${includedir_new}
---

opencv2.4:
---
Name: OpenCV
Description: Open Source Computer Vision Library
Version: 2.4.6.1
