glow: Build failed on macOS Sieera

When I tried to compile by just following the instruction in README on my mac, I encountered the following error and I’m sorry I’m not quite sure about this message. Is there anyone having seen this?? I had also tried it with Ninja, but it failed with kind of different error neither. I past both cases below.

  For compatibility, CMake is ignoring the variable.
