This is starting to become an issue, we see on GHA for ubuntu-latest

CMake Error at subprojects/samrai/CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

Hello, we use SAMRAI as a dependency in our project and need to move to cmake 4.x. Do you know if there any cmake code incompatible with the newer cmake versions?
For the moment we are adding the following to SAMRAI's CMakeLists.txt
set(CMAKE_POLICY_VERSION_MINIMUM 3.5),
but we don't know if it is completely safe to do so, is it? Thanks!
