That's great.

I'm confused about one thing still: The cdt4 web page says
"When you edit your CMakeLists.txt file, you are recommended to delete
your project and reimport it."
Why?   If it's because cmake has generated a new .project / .cproject,
does that mean you should do a build (or somehow otherwise trigger
a cmake run) before deleting and reimporting the project?
