If I understand correctly, you don't need a permanent process, you need
something that will work once for each of 70 libraries--or perhaps
fewer, since some of them may not need import libraries.  Then your port
will be done and you only have the (presumably less painful) maintenance
issues.

What about starting with a clean binary build tree (no OBJ files,
compile exactly one of the libraries (with "build only this project" so
it doesn't cause any other builds to be attempted), and use the Windows
Explorer "search" capability to see where the OBJ files were written?
(A "find" function that worked in a command window would probably work
better, of course.)

I don't know if this is a "good" solution but it might at least be
better than the alternative mentioned in (c).
