FYI, it would require to employ so called NMAKE batch-mode, which is
not trivial to configure, indeed.
Especially, if input/output paths need to be handled, etc.

Here is my question on using NMAKE batch-mode with tree of directories
I asked  a few years ago on microsoft.public.vc.ide_general [1] and
recently re-asked in SO [2] and MSDN [3].
My question remains unanswered.
