The AURs listed for Arch in the docs do not work on CachyOS: [Getting Started — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/user_guide/getting_started.html#linux)

They throw CMAKE errors as follows:

```auto
patching file CMakeLists.txt
CMake Error at CMakeLists.txt:25 (CMAKE_MINIMUM_REQUIRED):
Compatibility with CMake < 3.5 has been removed from 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.

Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

-- Configuring incomplete, errors occurred!

```
