Robert,

- cmake doesn't leave any traces except for a build/ dir. Most of us can
live with that.
- GNU Radio most certainly is big enough to warrant usage of CMake over
raw make. The maintenance load for such a build system would be
incredible, and I really don't know how you'd enable stuff like
ENABLE_GR_FOO and 'allow bad boost' with pure make.
- CMake also generates other things we care about such as Visual Studio
projects.

I'm not discouraging you to try and fiddle with make, but GNU Radio
isn't going to move away from CMake any time soon. But the make system
won't be 'simple', and I don't see the advantage.

As I said, it's your time -- but I would like to close this thread &
discussion on this mailing list. We've argued over build systems in the
past, and at this point it's not helping anyone.
Thanks, everyone!
