Since we were doing the module breakdown ourselves we could define
modules to avoid circular dependencies.  We separated implementation
dependencies from test dependencies so that library and test modules
could be built separately.  That helped break many circular dependencies.

So you want to have modules A -> B -> C -> A each build using all three
include directories?  This is still possible to do in pure CMake code
by loading a dependency declaration file from all modules ahead of time
as was previously done to get the inputs to the topo sort.
