Yes! The regression tests should definitely use the specification to
build/test the library.

This might make the full regression run take longer (if there are libs
that have dependencies on non-header-only libs, they will end up
getting built more than once). On the other hand, once the regression
tests get setup to test modular libraries, we can break up the
monolitic regression runs into much more manageable pieces (each
library + dependencies)...each of which will run much faster than the

This will allow us to get to a more CI like regression setup where we
can test libs as changes are applied. Right now most of the libraries
don't get changed but maybe once a month, but they all get
built/tested with each regression run. This causes the regression runs
to take > 8hrs on some toolsets. This means that (on runners with
multiple toolsets, like teeks99-02, 03, 05) we can go many days before
a new change gets tested for a specific toolset.
