CMake deprecation warning

[mqtthiqs]

Hi and thank you for your nice work.

Your CMakeFile starts with:

cmake_minimum_required(VERSION 3.1..3.18)

My CMake (3.29.1) is complaining that the minimum requirement, 3.1, is getting old:

[cmake] CMake Deprecation Warning at extern/libsamplerate/CMakeLists.txt:1 (cmake_minimum_required):
[cmake]   Compatibility with CMake < 3.5 will be removed from a future version of
[cmake]   CMake.
[cmake] 
[cmake]   Update the VERSION argument <min> value or use a ...<max> suffix to tell
[cmake]   CMake that the project does not need compatibility with older versions.

Maybe it is time to increase this minimum? Thanks in advance.
