When attempting to compile apt-cache-ng (on archlinux-arm aarch64), one gets:
```
CMake Warning (deprecated) at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 3.10 will be removed from a future version of
CMake.
Update the VERSION argument <min> value. Or, use the <min>...<max> syntax
to tell CMake that the project requires at least <min> but has been updated
to work with policies introduced by <max> or earlier.
This warning is for project developers. Use -Wno-author or -Wno-deprecated
to suppress it.
