Thanks for that detailed information. It appears from above that cmake_link_flags transforms the single element "-framework QuickTime" of the list from (2) into two separate list elements, -framework;QuickTime of (3) (and similarly for the other frameworks). This confuses cmake when it attempts to assemble the link command. Instead of processing -framework QuickTime as a whole it processes -framework and QuickTime separately. I am guessing here that when it sees QuickTime alone it doesn't really know what to do, and it bails out by prepending -l to it and hoping for the best. The cure for this issue is for cmake_link_flags to pass on whitespace-delimited flags such as "-framework QuickTime" without splitting them into two separate elements. I will have to think about the best way to implement that fix. Alan __________________________ Alan W.
