The CMake badge advertises 3.10+, but the repo’s CMake entry points currently require cmake_minimum_required(VERSION 3.16) (e.g., tests/sil/CMakeLists.txt and examples/api_client/CMakeLists.txt). Please update the badge (and keep the README prerequisites in sync) so users aren’t told an unsupported minimum CMake version.

The “PRs welcome” badge link uses http://makeapullrequest.com. Please switch this to HTTPS to avoid insecure redirects/mixed-content warnings and to match typical repository link hygiene.
