IIRC, cmake --build once invoked MSBuild in a VS environment, and MSBuild has the /maxcpucount option, see [1]. Have you already tried to achieve something similar with the VS2010 devenv-based mechanism?

Are configured build scripts an option? As a project knows for which build tool it is configured, it should be able to generate a build- tool-independent build script for itself.
