Bump required CMake version to 3.5
I'm consuming libogg via CMake and get the following warning with the latest CMake:
CMake Deprecation Warning at .../libogg/c9aea783bbaf472344144d3f98fb679be58b9eb0/CMakeLists.txt:1 (cmake_minimum_required):
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.
Can the version be bumped to 3.5
or the line be changed to cmake_minimum_required(VERSION 3.0...3.5)
?
