Browse Source 
## How to reproduce?

1. cmake version 4.0.3
2. clean srt build cache:
    `rm -rf objs/Platform-*`
3. `./configure`

compiling error output:

> Build srt-1-fit
> patching file
'./objs/Platform-SRS7-Darwin-24.6.0-Clang17.0.0-arm64/srt-1-fit/srtcore/api.cpp'

## Cause

CMake 4.x not long compatible with function cmake_minimum_required
(VERSION 2.8.12 FATAL_ERROR) with only min version anymore.

## Solution

add `add -DCMAKE_POLICY_VERSION_MINIMUM=3.5` to cmake cmd args.
