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'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!)
