    configure_file: Test that CMake re-runs on input change or output missing · 7f2dc8dc

    With the Makefile generators we expect that touching or modifying the
    input file of a configure_file, or removing its output, will cause CMake
    to re-run on the next build.  Extend the RunCMake.configure_file test
    with a case covering this.  Also check that CMake does not re-run if
    nothing has changed.
