Kind of figured that out looking around on github. I added a config (borrowed from one of your repos) to test for CXX17. I'm not sure its quite working for me yet but I will figure it out. A couple of questions:
1) I had C++17 in the system requirements in the description file but might remove it as I hope to make it check without CXX17. Does that have any impact on installation or is it only informative/notification? 2) If we need to adjust a package currently on CRAN owing to platform errors, should we keep the version the same or submit with a version bump? Thanks.
