Makefile poser to enable multiprocess compilations

[http://stackoverflow.com/questions/601970/how-do-i-utilise-all-the-cores-for-nmake][1]

This thread talked about nmake makefiles and the fact that 'most' start a separate cl.exe process for every single source file.

Alnitak said,"However most makefiles don't put multiple source files into a single invocation of the compiler - it开发者_JS百科's far more common for the .cpp files to be compiled to .o files individually."

Well, is it possible to create an nmake makefile which can compile mulitple source files with a single call to cl.exe?

(I'm not too good with makefiles so this might be easy to someone else!)

Well a couple of other links have led me to answer my own question in case anyone is interested...

Change older makefile system to take advantage of parallel compiles

So the answer is to use so called batch-mode inference rules.
