If you are used to Qt Creator’s kits for managing different Qt versions and compilers, CLion’s world of toolchains and CMake profiles can feel a bit opaque at first.
In this episode, Jesper Pedersen explains how CLion discovers Qt by default via qmake in your PATH, how to define separate toolchains that load environment settings from small setup files for each Qt version, and how to wire those toolchains into CMake profiles (like “Debug‑6.9” and “Release‑6.10”) so you can switch Qt versions much like you switched kits in Qt Creator – including a tip on disabling rarely used profiles so CLion doesn’t rebuild everything every time.
