Sorry, which of my 2 questions makes sense?

I've been able to restrict it to only IdealController, so the test builds without need for pulling in additional files. Is that an acceptable cost or should I use your trick for this class?

Your suggestion is to export only when BUILD_TESTING is true? If that's used elsewhere we'd have to document that the option does more than increase the build time. The performance impact aside it also means you can end up with visibility issues in builds with BUILD_TESTING=OFF (so the CI would need to verify both builds?).

I noticed ... several times until I finally had added all required files.

Doesn't (modern) C++ have class identities, type info and all kinds of similar metadata which could be different for the same code compiled in different modules?
