Xcode 11 should also be OK as long as you have the Command Line Tools
installed, which will provide the 10.14 SDK.

This warning is generated by this code:

It's triggered by the SDK that was found not being called
"MacOSX10.14.sdk". We always try to use an SDK with the version in its
name if at all possible, since we don't know which version "MacOSX.sdk"
actually is.

On my 10.14 system, this is the situation in the CLTs' SDKs directory:

% ls -l /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk
lrwxr-xr-x  1 root  wheel  10  4 Oct 13:30
/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk -> MacOSX.sdk

i.e. MacOSX10.14.sdk exists as a symlink.

The log likely contains more relevant information; please post the whole
thing to a pastebin so we can take a look.
