Patch up CMake such that it allows macOS to properly compile everything via "cmake .".
Add a required #include that seems to be required for Xcode 14 (and maybe 13?).
Note that, while this works on my system, either a macOS README file or a wiki update is recommended in order for users to understand the exact requirements (mostly Linux with some minor tweaks).
