 Dear maintainer, 
  
 your package has an autopkgtest regression with CMake 4, caused by 
 the removal of deprecated backwards compatibility settings. 
  
 You can find more information in my debian-devel announcement: 
 https://lists.debian.org/debian-devel/2025/04/msg00310.html 
  
  
 Hopefully relevant excerpt from 
 https://ci.debian.net/packages/m/msgpack-cxx/unstable/amd64/64721203/ 
 follows: 
  
  
  46s CMake Error at CMakeLists.txt:1 (cmake_minimum_required): 
  46s   Compatibility with CMake < 3.5 has been removed from CMake. 
  46s 
  46s   Update the VERSION argument  value.  Or, use the ... 
 syntax 
  46s   to tell CMake that the project requires at least  but has been 
 updated 
  46s   to work with policies introduced by  or earlier. 
  46s 
  46s   Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway. 
  46s 
  46s 
  46s -- Configuring incomplete, errors occurred! 
  46s autopkgtest [13:31:55]: test x3: -----------------------]
