CMake: Enable VS parallel builds for a good reduction in compile times

Passing -pthread to GCC as a flag makes it both link to libpthread, and make C standard library routines reentrant. This makes the additional explicit links unnecessary.

Additionally, on OSX, this is the default behavior, and clang will print a message about it being unused if it's present there.

These are implicitly linked by Xcode, but with this, you can also build it with any other generator, which does not have this behavior.

CoreFoundation is included as a part of Cocoa (which is an umbrella framework), and Cocoa is generally recommended to link against, rather than its individual components (CoreFoundation, Foundation, libobjc, ...).
