Trying to build the following but I keep running into issues ([maxe/QuickStart.adoc at master · maxe-team/maxe · GitHub](https://github.com/maxe-team/maxe/blob/master/doc/QuickStart.adoc)).

Basically, the code was written before M1 chips came out and I’m not sure what the optimal way to handle this is - 1) Build cmake from scratch (ie. [How do I build cmake from source as universal(arm64 and x86\_64) binary on Mac?](https://discourse.cmake.org/t/how-do-i-build-cmake-from-source-as-universal-arm64-and-x86-64-binary-on-mac/5862)), or 2) Find a work around solution?

The code in question will need to be recompiled to target arm64. Or you can target x86\_64 with your code. macOS supports running x86\_64 on arm64, but the granularity is at the process level. A single process must be all arm64 or all x86\_64.
