I’m not against bumping VTK’s minimum Xcode to 8, but we might not have to.
@spyridon97 Is there an alternative you can use here? Do we need to random name, or could we just ensure a unique name another way, e.g., by appending a number to the name and incrementing that number until a unique name is found, or something like that?
Note that the preprocessor macro VTK_HAS_THREADLOCAL can be consulted to determine if thread_local is available.
