I would go for a better use of the configuration manager in VS (debug,
release, runtime-debug=off etc) obviously driven by b2. Then I can think
of something like

b2 runtime-debugging=on,off arch=x86,x64 ...

or inside a file declaring the matrix of configurations.

that would generate several configurations in VS directly. There should
be something similar in Xcode and QtCreator.

This I think will be just painful, and this is why you also would like
to use a tool like b2 or cmake to do this job for you. Most of the time,
those configuration files are overkill in functionality and buried very
deep so that this is hard to manage properly.

Well, maybe we cannot avoid being completely orthogonal to cmake. b2
integrates its own build system (which cmake obviously does not) and in
that sense makes the tool as a potential replacement for many things.
But if the user choose to use an IDE, then again it honour this usage
fully rather than faking :) .
