ParaView. (To a lesser extent, VTK.)

Well, yes, one might argue that :-).

Also, because CMake allows either a source OR BUILD directory to be
given, such a configuration is almost certainly doomed. IMO, trying to
do an out-of-source build of a source directory that already contains an
in-source build *is* broken (i.e. no "arguably" about it)... and so is
an IDE trying to work around such situation.

At most, detect the situation and nicely report the problem to the user.
