VS 2017 shouldn't be a concern, see [1]. I think we can assume that CMake 3.16 is available for VS 2019 users, or that it is easily made available by updating VS. Anecdotal evidence: my VS 2019 installation, which is screaming for an update (16.8.2 -> 16.9.4) already ships CMake 3.18.

Hello Kyle Always using the latest is a good recommendation. The question is the minimum we can reasonably require the users to have installed. Upgrading is easy, but it's not as way as "$PKGCOMMAND install cmake" (where PKGCOMMAND is apt-get, zypper, dnf, yum, opkg, whatever), so requiring a version higher than the one users are likely to have creates a barrier for entry. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel DPG Cloud Engineering ___ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development ___ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
