I think people will be confused anyway as posted elsewhere. They
don't know which identifiers are features and which are just options.

...and who would that be? That's part of the problem. Another
problem is that the toolsets are totally inconsistent in how they

Yeah, that's important. But when even the people originally supposed
to be co-developers on BBv2 have been worn out trying to understand
the project's code, how are we going to get 3 or 4 more people to
devote enough time to actually succeed where others have failed, and
then make big contributions?
That's the bottom line, IMO. Who is going to step up and devote
enough time to make something that can work as well as CMake? In
CMake it's one line to build a graphical binary installer. We simply
don't have enough time and resources to reach that level of
sophistication. Further, the CMake model has some advantages in that
it is not trying to do configuration work every time you build. Yes,
we could do that in BBv2, too, but personally I just don't see the
point in trying to outrun a project that actually has a bunch of
knowledgeable developers and company funding behind it.
