Armadillo 15.0.* now makes C++14 the minimum compilation standard. For most packages, adapting to it can be very simple, and yours is one of them. In this PR we simply remove the declaration from DESCRIPTION's SystemRequirements, Makevars and Makevars.win -- and no other changes are needed.

Please see issues #475 and below for context, and notably #489 for this first wave of PRs. It would be terrific if you could make an upload to CRAN 'soon' to remove the reliance on C++11 which we needed in the past, but which is by now a hindrance. Of course, CRAN also now wants you to remove C++11 use and imposed a deadline on your package. Using the PR and re-uploading will help you meet this.

Please do not hesitate to reach out if I can assist in any way or clarify matters.

I added a second commit to also remove the files .DS_Store and the object files and libraries -- none of those go into the R package anyway as R CMD build knows to ignore them but we usually also do not ship them to GitHub. That was meant to go onto a second PR and I can move it over if you prefer to keep the two separated. Easy enough to do in git.
