From my experience I can strongly recommend CLion (https://www.jetbrains.com/clion/download/#section=linux) as a developer dream IDE for C/C++/Python. It’s very convenient and boosts your productivity a lot.
It’d be nice to see how JetBrains would recommend approaching ROS2 projects using meta workspace tools with isolated cmake builds. I like using CLion, but having +10 windows of CLion floating around with different degrees of code models when working simultaneously up and down the rmw/rcl stack is just not as fun.

I agree that having no build isolation sucks. If you have a non-catkin (CMake) project in your workspace, Catkin will refuse to build without isolation. The approach I’ve taken with Cartographer was to create a superbuild project I can open in CLion: https://github.com/larics/cartographer_superbuild
