    This means that we can use expressions of the form
    to get a list of the interface include directories of foo, including
    those coming from dependencies.
    We can't have a test of a target which has a single include directory in
    its INCLUDE_DIRECTORIES because the shell on the MSYS platforms transforms
    a single include directory to include a prefix, which is not what the test
    expects. We test a target with two directories instead as a means to
    test a target with no link dependencies.
