Your cmake output doesn't mention that it tried to build libcv.so so, I guess the reason you cannot find it is that it never tried to make it.
You may already have fixed your problem by just installing the relevant debian package. If not, it may be that you need to install this one https://packages.debian.org/squeeze/libcv-dev to get libcv. You have another problem. Squeeze is _very_ old. According to http://stackoverflow.com/questions/5212728/libcxcore-so-2-missing-in-opencv the opencv project renamed a bunch of libraries, so if at all possible you should upgrade your debian distribution. You may have all sorts of mismatches between the source you just built and the libraries you need -- which you will only find by trial and error.
