So I want use codeblock as IDE for my OpenCV program. I use CodeBlock 12.11, OpenCV-2.4.6.0, with MinGW and Cmake. I try to follow this tutorial http://kevinhughes.ca/tutorials/opencv-install-on-windows-with-codeblocks-and-mingw/

When I try with simple program like open a image it work. but when I want make program for face recognition, I find this problem.

it is at Build Message:

   ld.exe     cannot find -lhighgui
   ld.exe     cannot find -lcv
   ld.exe     cannot find -lcxcore

And it is at BuildLog

   C:/mingw/...../mingw32/bin/ld.exe: cannot find -lhighgui
   C:/mingw/...../mingw32/bin/ld.exe: cannot find -lcv
   C:/mingw/...../mingw32/bin/ld.exe: cannot find -lcxcore
   Process terminated with status 1 (0 minutes, 0 seconds)
   3 errors, 0 warnings (0 minutes, 0 seconds)

Can someone help me to solve this problem please?
