[CMake] Visual Studio rebuilding ZERO_CHECK

[Ben Medina]

For Visual Studio, I always disable the zero check project by setting
CMAKE_SUPPRESS_REGENERATION to true in my CMake cache. The downside is
that you have to run CMake by hand to regenerate project files. But
the experience of CMake running while Visual Studio has the project
loaded is quite terrible in VS2010, so it's not a big loss for me.
