From Farshid Lashkari, "I noticed that CMake forces a high stack size by default for all MSVC projects. This can cause problems for applications that use a lot of threads. I've added a new option MSVC_USE_DEFAULT_STACK_SIZE that will remove the explicit stack size and use the default MSVC size. Apparently this was only necessary for very old versions of MSVC but it's still around. I would argue that this option should be on by default, but I've left it off for now.
