I’ve been asked a few times about building Blender using Visual C++ Express with OpenMP. It’s an option in CMake and is being utilized by several parts of Blender. Sadly, it turns out that the Express editions of VC9 (or VC8 for that matter) do not support OpenMP. The full Visual Studio does though, so if you have it, you’re golden. I’ve updated the the tutorial to state that if you are using Express you need to set OpenMP in CMake to False. But if you have Visual Studio, I’ve included how to make Visual Studio support OpenMP.
