[IPOL discuss] 2 cmake questions

[Nicolas Limare]

Hi,

I am trying to write a basic CMake configuration.

2 questions:
* I find `mkdir build; cd build; cmake ../; cd ../` quite
  annoying. Isn't there a cmake command-line option to tell where the
  build dir is? 
* The default Makefile produces by cmake has no option to cleanup
  everything (Makefile, CMakeCache.txt, CMakeFiles,
  cmake_install.cmake). How do I remove everything produced by cmake,
  without doing it manually?

PS: Two important informations were missing for me in the cmake
tutorial in the IPOL wiki:
* we use add_executable() to list *all* the source for an executable
* target_link_libraries() is also for libraries installed on the
  system
So far, I am disturbed by cmake hiding all the transformation path
from source to executable and the notions of object file and separate
compilation.
