Sounds just about right :)


However back to the question itself:
to force a re-configure, one could "cmake -E touch"
the CMAKE_CURRENT_LIST_FILE, somehow during target building
or some such.
This is quite certainly not the most direct (nor elegant!) way
to force a reconfiguration (any ideas how to force it directly?),
but in some situations such a reconfiguration might help.
