[CMake] Parallel build with ctest 2.8.2

[Emmanuel Christophe]

Hi Dave,
Thanks for the information. I was not aware of the new ctest script
style: I got this from Luis when I set up the ITK nightly a while ago.

That's also what seems to appear on:
http://www.cmake.org/Wiki/CMake_Scripting_Of_CTest

Do you have any pointer for the new-style ctest?

Thanks,
Emmanuel
