[Dune] Dune and CMake

[Rene Milk]

Hello Dune,

I've been using CMake to build my DUNE module for some time now too. 
This semester I also use it in a DUNE related course I supervise where 
students are required to hand in single-source homework assignments each 
week that need to be built against a set of commonly accessible DUNE 
modules.
The setup I use is very bare bones. There are no checks for required 
libraries at configure time for example. Still, I find it very 
convenient to be able to hand a single CMakeLists.txt to the students 
they can use to build their assignments wherever they like.

I would add:
- Makefile generators, not only 'plain' unix Makefiles, but project 
files for some IDEs ( Code::Blocks, Eclipse, KDevelop, VS even )
- curses and Qt based interfaces to edit configure options (ccmake, 
cmake-gui)

I think a set of FindX style scripts for the core modules would be an 
awesome thing to have, even if CMake as a replacement build-system is 
far-off / unwanted.

Regards,
Rene
