error using already compiled version of openCV

I've used the already compiled version of openCV for Raspberry Pi. link for anyone who is interested

After trying to compile using this command line g++ test3.cpp -o test3 -I/usr/local/include/ -lraspicam -lraspicam_cv -L/opt/vc/lib -lmmal -lmmal_core -lmmal_util -I/usr/include -lopencv_core -lopencv_highgui -lopencv_imgproc -lwiringPi -lpthread

I get the following error lines.

//usr/local/lib/libopencv_stitching.so.2.4: undefined reference to `cv::gpu::ensureSizeIsEnough(int, int, int, cv::gpu::GpuMat&)'

//usr/local/lib/libopencv_calib3d.so.2.4: undefined reference to `cv::parallel_for_(cv::Range const&, cv::ParallelLoopBody const&, double)'

You have not linked the executable against several libraries that are required by the program

Try using this:

g++ -lpthread `pkg-config opencv --libs` -I/usr/local/include/ -lraspicam -lraspicam_cv -L/opt/vc/lib -lmmal -lmmal_core -lmmal_util -I/usr/include -lwiringPi test3.cpp -o test3
