Can the code comprising the D support for CMake be "packaged" up so that
it can be offerred to everyone direct from a DVCS repository?  SCons and
Waf have the tool concept to allow for this.  CMake must have something
analogous.  People can then make use of the D support with their CMake
without the necessity of it heading upstream -- though it would be good
for that to happen eventually.

Personally I prefer SCons and Waf over CMake, but would be happy to
trial CMake and its D support.  In fact the SCons tool I am trying to
force myself to work on and the CMake D support may help each other by
collaborating.

In one sense it is as easy as passing -m64 but there is also the issue
of the list of libraries needed at link time -- or does the CMake stuff
already pull in that information from dmd.conf?

Are these good enough to get traction compared to SCons, Waf, CMake,
Autotools, Make, Ant, Maven, Gradle, Gant?  This is a serious question
not a troll.  There is always space for a new, better build framework to
take the community by storm, but on the other hand if they are just side
shows then it dilutes effort and progress.
