thanks @Edouard2laire, I managed to build all binaries on my M2 mac and added via this commit - the binaries were built with minimized dylib dependencies and reduced sizes via strip command. I am closing this PR. please give those a try. if any of those have issues, please let me know (I noticed tetgen1.5 executable failed on some of the examples)

thx a lot. I'll open a PR on brainstorm to update the plugin :)
