Improve FILE(DOWNLOAD) and ExternalProject. Improve FILE(DOWNLOAD ...): - Add percent complete progress output to the FILE DOWNLOAD command. This progress output is off by default to preserve existing behavior. To turn it on, pass SHOW_PROGRESS as an argument. - Add EXPECTED_MD5 argument. Verify that the downloaded file has the expected md5 sum after download is complete. - Add documentation for SHOW_PROGRESS and EXPECTED_MD5. When the destination file exists already and has the expected md5 sum, then do not bother re-downloading the file. ("Short circuit" return.) Also, add a test that checks for the status output indicating that the short circuit behavior is actually occurring. Use a binary file for the test so that the md5 sum is guaranteed to be the same on all platforms regardless of "shifting text file line ending" issues. Improve ExternalProject: - Add argument URL_MD5. - Add verify step that compares md5 sum of .tar.gz file before extracting it. - Add md5 check to download step, too, to prevent unnecessary downloads. - Emit a warning message when a file is not verified. Indicate that the file may be corrupt or that no checksum was specified.
