I haven't ever had this be a problem, but FWIW one can find "Maximum
number of parallel project builds" under Tools -> Options -> Projects
and Solutions -> Build and Run and set that to 1 to disable target
parallelism. Of course, that's environmental rather than something
cmake could control

Greetings,
Any reason that cmake's own VS project generation doesn't make use of
/MP <https://msdn.microsoft.com/en-us/library/bb385193.aspx> to make use
of multiple cores? I added it manually, and cmake build times go
through the floor. That option has been present since VS 2008.

" The downside is that the IDE will still perform target level
parallelism along with object level parallelism which can lead to
excessive parallelism grinding your machine and GUI to a halt. It has
also been known to randomly create bad object files. However, the
speed up is significant so it is usually worth the extra trouble it
causes."
