ENH: Add the update step in between download and build. Add UPDATE_ARGS and UPDATE_COMMAND handling. Output a -complete sentinel in synch with the -install sentinel, but do not list it as an OUTPUT of the custom command. That breaks the chaining of add_custom_commands between custom targets, but allows for a file-level dependency expression that will cause proper incremental rebuilds. When earlier targets rebuild, subsequent dependent targets will also rebuild. CVS and SVN update commands are always out-of-date so that they always run to get the latest source. To suppress that behavior on a per-external project basis use an explicit empty string for UPDATE_COMMAND. The source will still be checked out from the repository prior to the update step by the download step.
