Update CMake minimum version to 3.5 to get rid of a new deprecation warning with CMake 3.27

[SRombauts]

Update cmake_minimum_required() to VERSION 3.5

Fix CMake 3.27 deprecation warning:

Compatibility with CMake < 3.5 will be removed from a future version of
CMake.

Update the VERSION argument <min> value or use a ...<max> suffix to tell
CMake that the project does not need compatibility with older versions.
