Bump the minimum CMake version to match current LLVM (#120)

* Bump the minimum CMake version to match current LLVM

CMake 4.0 removed compatibility with CMake versions below 3.5.
Therefore, it errors out on projects with a
cmake_minimum_required() less than 3.5.

(Since the last versions of CMake before 4.0, it already has been
warning that compatibility with versions below 3.10 is deprecated.)

Thus - this fixes building with CMake 4.0.

* Fix CI errors

- update gtest version
- clang-format MICmdBase.cpp
