xcodebuild spuriously hangs and blocks CMake configuration
On macOS Sierra (MacBook Air in my case):
- Download LLVM from llvm.org
- mkdir llvm/build & cd llvm/build
- cmake -G Xcode ..
Always hangs in random places.
EDIT: Here is an example of xcodebuild
hanging occasionally on a tiny project without CMake: XcodeHang.tar.gz
