Does this means that the library authors will need to maintain two build 
systems?

Oh, as lastly we have started to review also the tools I thought it 
works like that also for a new build system, but you know better how 
Boost works. I think it is time to start this discussion. Please could 
the interested parties start a thread that results once for all in a 
decision on whether CMake based build is adopted or not?

No, I didn't read it before. I've read it now. I see that there is yet 
some work to do yet. If the library authors should maintain the CMake 
build system they could participate in the writing of these CMake files, 
of course once the Boost community decide to adopt the new build system.

Note that I'm not completely against the adoption of CMake, as it could 
have some advantages, but the liabilities should be considered also when 
the decision will be taken. For that we need to start a discussion, 
goals, documentation, who will take the decision, ....

Best,
