Two of my projects require gigantic amounts of RAM for compiling. I already figured out, how to make certain, that they do not build in parallel -- by specifying build order. Now I also want to make certain, that there are not multiple .cpp files being compiled from the same project in parallel with the one which is critical. Anybody any clue? But I definitely want to keep the parallel build option enabled for all the other projects.
Use the /MP argument to the build, as described here.
