I'm trying to add "Launch Groups" as an option within my Run/Debug Configurations in Eclipse Luna, but it just won't show up.
From the CDT Update Site I have installed both the "C/C++ Development Tools" as per this answer for running multiple launch configurations at once as well as the "C/C++ Remote Launch" package as per this answer for what installable component provides 'launch groups' in Eclipse, but Eclise still doesn't give me the option to add new "Launch Groups".
