[CMake] Clearing all cmake files

[Mike Jackson]

And hence the reason to use an "out of source" build. That alleviates  
the problem.

Now, just in case you are still new to cmake, here is a subtle FYI  
about "out of source" builds. The build directory can be a sub  
directory of your project.

MyProject/
     src/
     includes/
     Build <=== CMake Build directory

If you setup like this then cd into the "Build" directory and do  
"cmake ../" and let cmake run. Certain types of IDEs like this  
approach better than others.

Or you can do:

MyProject/
MyProject-Build/

Your choice. But since CMake does create lots of files, using one of  
these techniques is what the CMake developers assume.

I made that same mistake a few times, even tried to "fight it" by  
insisting on in source builds. After a while I got tired of fighting  
and used out of source builds. After that everything fell into place.  
CVS/SVN worked better. Cleaning out CMake was easier. Multiple Build  
types was easier. It all worked as it should. I have never looked back.

Now, you may have a use-case that prohibits you from utilizing either  
of the above situations. If you do I am sure we would like to hear  
about it.

Philosophically I kinda agree that some sort of shell script should be  
able to be generated with a list of files that CMake creates. In  
practice, this isn't needed.
