Root Cause

CMake policy warning about deprecated behavior.

generic

Workarounds

  1. 90% success Set cmake_minimum_required(VERSION 3.20) to use new policies by default
  2. 88% success Set specific policy to NEW: cmake_policy(SET CMP0XXX NEW)

Dead Ends

Common approaches that don't work:

  1. Set cmake_policy(SET CMP0XXX OLD) for everything 72% fail

    Uses deprecated behavior

  2. Ignore all policy warnings 68% fail

    Breaks on future CMake versions
