If you're just going to set it to the number of processors on the machine, you might as well just use /MP, which means use the number of processors on the machine. The only time you need a number is when you want to use a different number of parallel processes, such as only using half your capacity because something else is using the other half, or leaving one or two cores open for GUI work. -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
