Interesting. I wouldn't think you need to pass in the COMPILER args since it should use the same settings as the parent project. Post 1.8.6 code has been tested as an external project, but with compression libs explictly enabled/disabled. Have you inspected the generated files to determine if they make sense. How about the log files for any clues? Can you use a 1.8.7 snapshot? There was significant cmake code changes after 1.8.6 concerning use as an External Project.
