Why are you installing `igraph` from source? It seems from [CRAN igraph](https://cran.r-project.org/web/packages/igraph/index.html) that there are binaries available for macOS arm64.

If, for some reason you really do need to install from source, please see some specific instructions for installing from source here: [How to compile R/igraph from source, with all features enabled? - #5 by szhorvat](https://igraph.discourse.group/t/how-to-compile-r-igraph-from-source-with-all-features-enabled/1190/5).

If you still can’t install `igraph` in R following these instructions, let us know. Please provide full details of the installation log, so that we know a bit what might be going on.
