Update minimum version of cmake

[pgaltieri]

When compiling libml on Fedora 42 I get a lot of deprecation warnings

CMake Deprecation Warning at vendor/gemmlowp/contrib/CMakeLists.txt:5 (cmake_minimum_required):
Compatibility with CMake < 3.10 will be removed from a future version of
CMake.

Update the VERSION argument value. Or, use the ... syntax
to tell CMake that the project requires at least but has been updated
to work with policies introduced by or earlier.

Many of the CMakeLists.txt files have the minimum version of cmake as 3.5. My current version of cmake is 3.31.6
