[Dune-devel] cmake oddities

[Christoph Grüninger]

Hi Oliver,
thanks for testing CMake and your feedback.

I don't have a solution for the CMake policy CMP0022 warning. I spend a
lot of time trying to work around, but it boils down to a question of
compatibility. The only non-hacky way to get rid of the warning would be
to require CMake 2.8.9 instead of 2.8.6. At least CMake 2.8.12.1 reduces
the warning to one per external grid library, compared to 2.8.12 which
emitted the same warning over and over again.

I always though that's caused by CMake and they know what they do. I
just checked and METIS 5.0.2 has this part, too. If you insist, I will
find out the rationale of /__/.
