Apparently CMAKE_SYSTEM_PROCESSOR could be used:

Edit: not sure actually. Looks like that variable is optional:

> Improper CPU flags failing pyarrow install in ARM devices
> ---------------------------------------------------------
>
> Key: ARROW-7422
> URL: https://issues.apache.org/jira/browse/ARROW-7422
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.15.1
> Environment: ARMv8 Jetson Nano with CUDA capable GPU
> Ubuntu 18.04.1
> gcc version 7.4.0
> cmake version 3.10.2
> Reporter: Abishek Muthian
> Priority: Major
>
> Improper CPU flags failing build in-spite of routines explicitly checking
> whether compiler supports those flags. Since pyarrow package in the pip has
> configuration errors, building from the source is the only option but the
> installation fails due to several issues, this being one of them.
> Had to manually remove SSE4, AltiVec related flags from the
> *DefineOptions.cmake* & *SetupCxxFlags.cmake* to avoid this error in-spite of
> routines to check whether compiler can handle this flags.
> There are other errors after doing this(they don't seem to be related to CPU
> flags, so I have opened separate issue).
> Log is in the external issue URL.
