 First, we set an environment variable to make our work easier. This will hold the build directory of
 our OpenCV library that we use in our projects. Start up a command window and enter:

 Here the directory is where you have your OpenCV binaries (*extracted* or *built*). You can have
 different platform (e.g. x64 instead of x86) or compiler type, so substitute appropriate value.
-Inside this, you should have two folders called *lib* and *bin*. The -m should be added if you wish
-to make the settings computer wise, instead of user wise.

 If you built static libraries then you are done. Otherwise, you need to add the *bin* folders path
 to the systems path. This is because you will use the OpenCV library in form of *"Dynamic-link
