From c608000a2a57faaac6e1789f8502e734db5ddb0e Mon Sep 17 00:00:00 2001 From: Brad King Date: Mon, 15 May 2017 13:05:46 -0400 Subject: Xcode: Work around xcodebuild spurious hangs in try_compile `xcodebuild` occasionally hangs on some macOS machines (and can be reproduced independent of CMake). It only happens a few times in 1000 runs, but configuration of a large project calls `try_compile` many times and therefore frequently hangs due to this problem. I've been unable to reproduce the hang when using a scheme to build, so always generate a scheme in `try_compile` projects to work around the problem.
