[ros-users] Linking to packages with shared libraries

[Nicholas Butko]

While you're at it, it would be really helpful to update to the latest version of window_cocoa.mm in modules/highgui/src -- there was a really bad memory leak that is fixed now. However it is not fixed in the version pulled by ros.

Thanks for your help.
