You don’t have to use the sdk install and probably don’t want to if You’re developing Qt OSS software. Target the distribution or build it Yourself. https://wiki.qt.io/Get_the_Source
I’ve been doing that, too. Hell, I’ve got SDK builds so small that they work great on Github Actions. And obviously, on Linux, you can just grab dev files and Qt Creator right out of your repos, making it even simpler.
