how to do opencv haartraining with opencv from ROS?

edit

I am new to opencv haartraining and really need some help. I want to train my own haar classifier so I followed some step by step tutorials:

but I am stuck because I can't find the haartraining folder which is needed in --> cp src/mergevec.cpp ~/opencv-2.4.5/apps/haartraining

The problem is I am using opencv installed with ROS hydro (version opencv 2.4.6) and I cannot find where is located the haartraining folder which I need.

I tried using bash comands: sudo find / -iname 'haartraining', sudo find / -iname 'apps', sudo find / -iname 'opencv', sudo find / -iname 'opencv2' but none of these helped me find the haartraining folder.

I am working on Ubuntu 12.04.

Can you suggest how to find the folder haartraining, or how to do the haartraining with opencv from ROS?

Please help me
