----------------------+--------------------
 Since the most recent update, CMake refuses to build on MacOS.
 The failure generates tons of output, but the important bit is this:

 :info:configure     ld: warning: The i386 architecture is deprecated for
 macOS (remove from the Xcode build setting: ARCHS)
 :info:configure     ld: warning: ignoring file
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/lib/libSystem.tbd,
 missing required architecture i386 in file
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/lib/libSystem.tbd
 :info:configure     ld: dynamic main executables must link with
 libSystem.dylib for architecture i386
 :info:configure     clang: error: linker command failed with exit code 1
 (use -v to see invocation)
