Steps to reproduce

Hi,

I'm building libpsl-native using CMake 4.0 and it's currently failing with:

2025/06/25 04:26:24 WARN CMake Error at CMakeLists.txt:1 (cmake_minimum_required):

This removal has been documented in CMake 4.0's release notes.

Thanks.

CMakeLists.txt:1 から始め、GNU/Linux 上で CMake 4.0 を使用して設定の失敗を再現します。サポート対象の CMake 互換性に合わせてプロジェクト設定を更新し、その後、CMake 4.0 で libpsl-native のビルドが成功することを確認します。
