The visual compiler itself can do parallel builds. You need to

Yes, but that requires that all the source code you need to build

passed to cl.exe in one invokation, something the VS IDE can do,

makefiles typically don't. Maybe NMAKE has some special syntax to

that case.
There is no special syntax. You just pass the additional compiler
flag to the compiler. We are using this at our company w/o any

But if cl.exe is only invoked with one source file at a time, how can it parallellize over all the source files?  As I understand it, the /MP flag allows the compiler to parallellize over the source files it receives on the command line.

How does your NMAKE makefiles look which handles this?

It wouldn't be that complicated. You'd probably do it the same way you pass the list of object files to the linker.
