title: Cannot compile mergevec.cpp from Haartraining tutorial
body: <p>I have been following this tutorial ( <a href="http://note.sonots.com/SciSoftware/haartraining.html" rel="noreferrer">http://note.sonots.com/SciSoftware/haartraining.html</a> ) to do some Haar training.  I am currently stuck on creating the training samples, specifically the combining of the .vec files.  I am provided with this ( <a href="http://note.sonots.com/SciSoftware/haartraining/mergevec.cpp.html" rel="noreferrer">http://note.sonots.com/SciSoftware/haartraining/mergevec.cpp.html</a> ) file and a description of how to build it for Linux (Ubuntu 11.04).  Here lies my problem, I am unable to build the mergevec code.  The only error is "fatal error: cvhaartraining.h: No such file or directory."  I have checked to make sure that cvhaartraining.h is in the same directory as mergevec but have found everything to be right where I would expect it.  At this point, I am at a loss of how to solve this, so any help would be greatly appreciated.</p>
