Comment (by miken32):

 It's trying to find header files in
 `/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk`
 but `MacOSX10.15.sdk` is the only one bundled with XCode 11. Before that
 failed command it is using
 `/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk` without issue.

 Worked around this by doing this:
 {{{
 sudo ln -s /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk
 }}}
