How do I build java libraries into existing OpenCV 2.4.10 installation?

edit

I successfully built OpenCV 2.4.10 on a Raspberry PI 2 and tested it with a simple C++ program; however, when I went looking for the java jar I couldn't find it. I followed very detailed instructions for installing OpenCV on a Raspberry PI, but I wasn't looking at the time to ensure that the java libraries were included. I have verified that I have all the dependencies by running cmake in a new directory and checking the output for the java targets as shown in the tutorial.

Is there a simple way to build just the java libraries? I am a novice when it comes to cmake and make. I have done very little C and C++ programming and that was many years ago with a nice IDE.
