    ExternalProject: Reattempt download when verification fails. · b5e2265f
    Matt McCormick authored
    When downloading an URL with ExternalProject, reattempt the download three
    times if the file hash verification fails.
    The re-attempt is limited to non-local URL's.  The same download CMake script
    is re-used after removing any file that resulted from the previous download
    attempt.  Up to three re-attempts are performed.
