Amazing to see this still maintained. Qt creator was my go-to IDE about 20 years ago. At this time, Visual Code, Eclipse, NetBeans and friends had been incredibly resource demanding where Qt creator felt pretty lightweight yet powerful.
I'm still using QtCreator as my go-to cross-platform C++ IDE! It might give CLion a shot since there's now a free version, but so far I haven't really felt a need to do so.
I switched to using JetBrains for most things recently, and I'll say this about CLion: it is incredible and my instant go-to for CMake-based projects. For any other build system it is a massive headache to get working in my experience.
Every year I try to use CLion for my project and every year it fails miserably compared to Qt Creator for indexing, navigation, etc. on large-scale codebases. It has more complete refactors though.
