Add cmake build option for disabling OpenMP (#986)

Browse source 
In my case this is because of issue #985, but there's also the use case of being able to test without OpenMP. For example, to disable it on my system in order to test if the crash had anything to do with OpenMP, I had to manually edit `CMakeLists.txt` each time I wanted to turn it off and on again.
