We could do this by automatically creating a test per library that
runs inspect on the library's sources. VTK actually does this, and
it's quite helpful. Once the libraries are modular, it'll be easy to
just point inspect at the base of that library's sources.

I've added this to the "CMake TODO" list on the Trac.

Automatically building the binary installers is easy; testing them is
a little tougher, because some of them are graphical and might require
some "clicking". Perhaps they can still be driven from the command
line? I'm not sure.

Either way, I have a preliminary implementation of testing Boost
against an installed tree. Essentially, one does a build+install
(without tests), then a separate build of the regression tests using
the installed headers and installed libraries. This is the eventual
goal for our testing environment, since it mimics the way a user would
use Boost. Adding the extra step of building a binary installer and
installing that for testing... that would be even better.

CPack does not build 7zip archives. We've only been using 7zip
archives for Boost source-code releases, right? We can create those
without even involving CPack... binary releases using 7zip would
require a bit more effort, and possibly some CMake hacking.
