Boost Build has the ability to run a 'program' and change the logic of
what is to be built, or how something is to be built, based on the
return value of that program. I do not know CMake well enough but I am
assuming that CMake also has such a feature, else it would really be
deficient IMO. That is essentially what Boost Config offers and Boost
Predef offers and my briefly discussed Cxxd library also offered,
through the facility in Boost Build which allows this. Porting Boost
Config and Boost Predef to use CMake would have to port this ability
also in an easy to use way, since other libraries also depend on the
Boost Config and Boost Predef facilities when they use Boost Build for
