[cmake-developers] Better Eclipse CDT support

[Manuel Klimek]

Pulling in a few more people (suggested audience from Sergey), please
tell me if I'm CC'ing a list that doesn't make sense.

Context:
Oliver is currently working on making eclipse support for CMake a lot
better. I heard that Andrew is working on configuration of includes
and defines in eclipse, so there might be potential for coordinating
efforts to make eclipse and cmake work better together and provide a
really nicely integrated development setup.

Cheers,
/Manuel
