I don't think it's sufficiently useful, but there is a CONFIGURATIONS
parameter on add_test which allows limiting tests to specific named

Probably more useful is to condition it on some project-specific
property that's defined when you want to run tests.

That sounds simple enough when you're a single project being built
directly or not.

It doesn't sound like it would work when someone wants to run "all Boost
tests", or if someone using your library as a dependency does indeed
want to run your tests.
