CMake 4.0 drops support for CMake <3.5, so minimum versions need to be adjusted for forward compatibility. As long as we are touching the minimum version, let’s advance to 3.12, which can be considered the oldest “modern” CMake release, and which is available in all known supported Linux distributions today.

I’m confused. The first suggestion seems to change this to a version range, but in the wrong direction (3.12...3.5 instead of 3.5...3.12), and then the second suggestion … changes it back?
If you do have a concrete reason to want to support such old CMake versions, 3.5...3.12 would be a reasonable alternative to 3.12.

Thanks @musicinmybrain :)
Also ping @Mengna-Li : your suggestion does not seem right. Is this a typo ? And what is the rationale ?
