$ rm CMakeCache.txt

CMake error: build dir not empty

I think it would be impossible to determine if the build dir contains 
*only* files generated by cmake. (For example, you changed the 
CMakeList.txt's quite a bit - new files and such - and then deleted the 
cache and Makefile's. The build dir may indeed contain only build files, 
but you no longer have anything to tell you what those build files /are/.)

Your eyes are weary from staring at the CRT. You feel sleepy. Notice how 
restful it is to watch the cursor blink. Close your eyes. The opinions 
stated above are yours. You cannot imagine why you ever felt otherwise.
