  <p>But what directory do I pass to which parameter? These do not look relevant in specifying the cairo library:</p>

    distclean: removes the build directory
    install  : installs the targets on the system
    list     : lists the targets to execute
    step     : executes tasks in a step-by-step fashion, for debugging
