This part here is inaccurate, at least with the current CMake and Visual Studio:
"To set the flag you will have to edit the CMake cache with the cmake-gui
and add it to the CMAKE_CXX_FLAGS and the CMAKE_C_FLAGS."
This is all we do in the CMake file that we include in all our projects:
add_compile_options(/MP$ENV{NUMBER_OF_PROCESSORS})
If you don't have a NUMBER_OF_PROCESSORS environment variable, you just get /MP.
The oversubscription part is still true, but I've never seen randomly bad
object files.
