It is a header-only library, so this package is BUILDONLY:=1; the headers and CMake config files land in staging_dir for consumers to pick up via find_package(GCEM). Needed as a build dependency for fluidsynth >= 2.5, whose upstream build expects gcem at configure time and (absent a system copy) falls back to a CMake-time download from GitHub - which breaks in offline / restricted-network build environments such as the OpenWrt CI. Pinned to commit 012ae73c (2024-04-28), the revision referenced by fluidsynth 2.5.x's bundled FindGCEM.cmake / git submodule. CMAKE_POLICY_VERSION_MINIMUM=3.5 is set because upstream's CMakeLists.txt declares cmake_minimum_required(VERSION 3.1), which trips current CMake's deprecated-policy guard.
