That is a myth. If you are using Linux, then this as easy as calling
CXX=g++-4.7 cmake <source-directory>
just try it yourself with the attached minimal cmake_test problem and
inspect the file CMakeCache.txt

Can I ask you a favor?
We have implemented a lot of conversions inside of dune-control to
make it possible for users to use the exact same opts-file that works
for autotools. As you seem to have such a working opts-file can you
please just try that (with cmake) and open a proper bug report if it
does not work as expected? That would be really great.

I cannot confirm this. But our autotools usage is of course a lot more
tested over the years (did make quite some of our hairs grey as we
struggeled with its intrinsics). I do agree that our CMake stuff might
still not be on par, but people are working hard for that.
Do you need more support with DUNE or HPC in general?
