Options.inc file not found when integrating Xcode with Ninja

Hey everyone!

I'm following the Getting Started Guide to get setup in Xcode. I've completed the Using Ninja with Xcode steps. When I run I get the following error: 'clang/Driver/Options.inc' file not found. I'm able to build/run just fine without Xcode.
