       Download Target.
       Name must be unique.
       By design, targets are executed only once per project.

       Usage:

       package: URI

       expectfileordirectory: Skips the download and extraction if exists

       outputfolder: Folder to store a downloaded file.
                     By default "$(BaseDir)libs", if empty

       outputfilename: If not empty, overrides filename from URI.
                       .exe files don't get extracted

       extractto: Folder to extract an archive to
