Fix composable_kernel build with CMake 4.x (ROCM-24848)#4903
Merged
Conversation
CMake 4.x (shipped in TheRock 7.14.0) removed compatibility with cmake_minimum_required < 3.5. The pinned composable_kernel revision (ad0db05) still declares an older minimum, causing cget builds to fail. This matches the existing pattern used for protobuf, nlohmann/json, and msgpack (added in PR #4714). Fixes: ROCM-24848
