The question is: By the time qt6 will be out, will the requirement of cmake minimum version be met by, say, the latest (two) Ubuntu LTS release? (Or Macos, ...) The answer is that, best case, this is doable if qt6 is not released before 2022 or 2024. (Current req. Is unreleased cmake 2.15. assuming the minimum req. is not bumped, which is very unlikely given the lack of support for Android, iOS, etc...) > If distro X (e.g. *buntu 20.04) happen to ship a sufficient version > when it arrives, then great.

Then convince the boot2qt team to force yocto to use the latest bleeding edge cmake version for their stable branch... Good luck with that. And then, which is my point, you're asking your customers to build/install Qt build system in order to build Qt itself. That is wrong. The world is not spinning around Qt, sorry for the bad news. I prefer a transparent self-bootstrapped Qt over an explicit two stages one. Right now the cmake build system doesn't respect the initial requirements that were used to ditch contenders. This is in no way a democratic process. This is selective hearing, reqs for cmake are artificially lowered while reqs for contenders are artificially raised. I have no doubt that cmake will be Qt6 build system, this is your choice, I'm just asking to stop this simulation, and I'm asking you to take your responsibilities, if building Qt6 is not supported on mainstream platforms I might consider switching away from Qt. Last comment: Please think about embedded Linux, qnx, vxworx, iOS, android and whatever next os is coming. Cmake is not yet ready for that.
