At our lab most people tend to use the two mentioned by Martin (QtCreator and Eclipse CDT), but recently I’ve tried and also heard good things about CLion: https://www.jetbrains.com/clion/
The thing that I like about CLion is the clean and clever integration with CMake, and that it ‘just works’ with ROS packages without having to do special configuration (as long as you are running it from a console that has the ROS environmental variables).
