What I could do to make it *really* idiot-proof also in my situation, is
to force a reconfiguration for every call.

I could for example add a target

add_target(reconfigure
   ${CMAKE_COMMAND} .
)

and make all the other targets depend on it.
So I'm sure that I never have to rerun cmake myself, how does that sound?
