      To test the results, issue: <command>ninja test</command>. The tests

        When installing, the build process does some additional
        linking.  If you do not have Xorg in /usr, the LIBRARY_PATH
        variable needs to be defined for the root user.  If
        using sudo to assume root, use the -E option to pass
        your current environment variables for the install process.
