I'm with you up to this point.

That's a whole different topic.

There is something deeply flawed about the modularization design if it
requires a switch to CMake. Indeed, one of the reasons I want to try
the modularization design on one of my libraries is to verify it is
compatible with both our current build system and build systems that
have nothing to do with either Boost.Build/bjam or CMake.
