OK for the concept of out-of-cource build, easy to cleanup with a
simple rm -rf. But for such out-ou-source build, it seems that I HAVE
to manually move to this build dir wth CD. The syntax provided by
Pierre dows not create the cmake files in the build dir.

I just want something like 

  mkdir /path/to/build/
  cmake -option /path/to/build/ /path/to/src/
         ^^^^^^^^^^^^^^^^^^^^^^
                               `-> would create CMakeFiles, CMakeCache,
                                   etc. in /path/to/build/
  make -C /path/to/build/
  rm -rf /path/to/build

So far, it seems that cmake always create the CMakeStuff in the
current directory.

I think my two wishes are incompatible in the cmake world:
* a want a command (a make, cmake or a simple rm) to cleanup everything
* I want to manage all the build process without moving
