Update CMake minimum required version to 3.10

Daviey · Daviey · commit c49fc6ddb1a3 · 2025-10-09T12:38:35.000+01:00
CMake 4 removed compatibility with CMake versions < 3.5, and versions between 3.5-3.10 are deprecated. This change updates the minimum required version to 3.10 to ensure compatibility with modern CMake versions including CMake 4.x. This issue is affecting NixOS users (see NixOS/nixpkgs#450198) and will likely impact other distributions as they upgrade to CMake 4.x.
