I can configure and compile by adding a soft link
sudo ln -s /usr/local /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/local

And then pass to configure the preprocessor argument
CPPFLAGS='-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/ -I /usr/local/include’
