I usually build out-of-source. What is built out-of-source is up to
the user. Typically, we build A once and leave it untouched and then
work on an isolated out-of-source build of B. SomeProject is usually
used only when everything is bundled into a single installer.

This is interesting; I did not know about the IMPORTED property. I
could integrate this query into my hand-crafted export macro and I am
quite sure that it would help.
