Because you haven't built it yet.
What your teacher is having you do is learn to compile from source code. The ./configure script you just ran doesn't actually build anything, nor does it place any files in the directory you chose. It merely sets everything up.
You will most likely be instructed to type "make" at the command prompt (yes, just that one word, but make sure you're in the same directory as the ./configure file).
"Make" will build it for you (hopefully). However you STILL won't have anything in that directory you referred to.
The final step is "make install." This puts everything in the right place, and installs the program. Then you cd to your directory you're looking for and stuff will be there.
Obviously, if your teacher hasn't told you to type "make" or "make install" DON'T DO IT, lol. There may be a specific reason for this, and you don't wanna get lost and have to re-download the source code.
