[Dune] changing to cmake

[Atgeirr Rasmussen]

I have had the same need. My solution is to pre-populate the cache with the -C option to cmake:

    cmake  -C my_cmake_options.cmake the_dir_with_CMakeLists.txt

where the my_cmake_options.cmake file contains:

    set(CMAKE_CXX_COMPILER "clang++" CACHE STRING "C++ compiler")

and other things that I need often. With the above, the correct compiler is chosen (clang in my case).

I am not sure how to do this via dunecontrol, but perhaps adding the -C <file> option in CMAKE_FLAGS would work.
