What would be missing from VS Code or VS Codium that an IDE needs?
I'm an ex Visual Studio user, now writing all my code in VS Codium. I organize my project tree in VS Codium, I build from it and, like a Visual Studio user, I press F5 to debug, set breakpoints and inspect variables.
And that's just the default install using the vanilla C/C++ extension it ships with, not some complicated setup that takes any time to get working.
