I guess that brings up the obvious question: how does one use this target and take advantage of multiple processors? Basically, I'm calling it within a python loop that permutes various projects and configurations (release/debug/shared/static...) then puts the results on a self-hosted CDash server with make NightlySubmit. I thought it used to parallelize the builds, but the script is a few years old and I wouldn't bet my life on it. Dave
