[cmake-developers] Review request: extract-cmMessenger branch

[Stephen Kelly]

Hi,

I have pushed a extract-cmMessenger branch to my clone:

 https://github.com/steveire/CMake/commits/extract-cmMessenger

The motivations are:

* Decrease responsibilities of the cmake class. CMake uses too few
classes for too many things
* Make it possible to make add first-class handling of messages about
missing packages (for example) to cmake-gui by making methods on
cmMessenger virtual and subclassing
* Make it possible to emit messages through the daemon (also by
subclassing) together with backtrace and message type, relieving clients
from having to parse the text.

I'm interested in what you think of the approach.

Thanks,

Steve.
