Fixes #273.
Summary
- keep the existing CMake 3.1 minimum requirement
- set the CMake policy compatibility version to 3.10 so CMake 4.x no longer rejects the project at
cmake_minimum_required()
Verification
- actual pre-change source with CMake 4.3.2 fails at line 1 with
Compatibility with CMake < 3.5 has been removed from CMake.
- PR head with CMake 4.3.2, Ninja, and GCC 16.1.0 configures successfully and generates the full library build graph
- PR head also configures successfully with the official CMake 3.1.3 binary, confirming that the range syntax preserves the declared 3.1 minimum on pre-3.12 CMake
- a MinGW build reaches source compilation and then stops because TinyALSA targets Linux and MinGW does not provide POSIX
poll.h; this is independent of the CMake policy change
git diff --checkgit ls-files --eol CMakeLists.txt
Sorry, something went wrong.

Keep the existing 3.1 minimum while setting the policy compatibility version high enough for CMake 4.x.
