This is not in our current plans; Michael Davidsaver may be the only developer 
working on EPICS Base who knows much about CMake.  If someone wants to propose 
merging a replacement to the existing GNUmake-based build system they will 
have to show that it meets all our current requirements, for example:

* Supports all our host platforms (Linux, Solaris, Windows, Mac OS)
* Handles cross-builds for other architectures
* Can build multiple architectures in the same source tree
* Can build just a part of the tree, meaning a directory or architecture
* Parallel builds to maximize performance

I'm sure there are a few other requirements that I've missed.  Any replacement 
would need to come with scripts to convert existing EPICS Makefiles into their 
replacement files, as there are now thousands of independently created EPICS 
modules and IOCs being built at sites around the world, and they all have 
multiple Makefiles in them.
