Build fails with CMake 4.0

Hi,

While building your software with CMake 4.0, I get:

2025/06/24 20:10:00 WARN CMake Error at CMakeLists.txt:12 (cmake_minimum_required):
2025/06/24 20:10:00 WARN   Compatibility with CMake < 3.5 has been removed from CMake.

This is mentioned in CMake 4.0's release notes.
