I just installed and built and opencv for linux and am trying to run some bundled in test programs e.g. ./opencv_perf_objdetect, I am getting errors shown below. Where can I get data files needed to run inbuilt test and sample programs?

opencv/opencv-2.4.3/OpenCV-2.4.3/svn/opencv/modules/ts/s rc/ts_perf.cpp:1128: Failure Failed Requested file "./cv/cascadeandhog/cascades/lbpcascade_frontalface.xml" does n ot exist. params = ("cv/shared/lena.png", 24) termination reason: aborted by the performance testing framework
