Use a range for CMake minimum versions, 3.2...3.12: support CMake 4.0

musicinmybrain · musicinmybrain · commit 1692717e0541 · 2025-03-06T10:52:44.000-05:00
CMake 4.0 drops support for CMake <3.5, so minimum versions need to be adjusted for forward compatibility. Since CMake <3.10 is already deprecated, and 3.12 is the first “modern” CMake release, let’s support policy versions up to 3.12. https://cmake.org/cmake/help/latest/command/cmake_minimum_required.html
