Specify C++11 as a System Requirement

Describe the bug When I try to install version 2.4.5, the install fails due to apparently not knowing the variable declaration auto.

To Reproduce


install.packages(pkgs = "/home/pdonn/openxlsx_4.2.5.tar.gz", repos = NULL, type = "source")
Installing package into ‘/home/pdonn/r_packages’
(as ‘lib’ is unspecified)

* installing *source* package ‘openxlsx’ ...
** package ‘openxlsx’ successfully unpacked and MD5 sums checked

* removing ‘/home/pdonn/r_packages/openxlsx’
Warning in install.packages :

I suspect the issue is due to me being on a very old system. Unfortunately I cannot upgrade it for the foreseeable future:

Additional context I found this page: https://teuder.github.io/rcpp4everyone_en/050_c++11.html

There it says:

As a test I added that one line to DESCRIPTION and then successfully was able to install the package!
