This happens specifically on macOS, where for some reason it's using the vendored GLPK. I mentioned it here: https://github.com/igraph/rigraph/pull/1347#issuecomment-2085374207
It happens either because GLPK is not available in that build image or because it is available but our configure script doesn't properly detect it. I can't see anything wrong with the configure script, so I suppose it's the first.
Note: Fixing up the vendored GLPK to CRAN standards is not realistic or reasonable, what's needed is to use an external one.
The current failures are different, failure to install {graph} (not {igraph}) on two platforms.
