Typically, when an R package wraps a third-party library, you need a development version of it installed in order to install that package from source. If you're running R from the Linux Mint repos, try to install r-cran-nloptr from Linux Mint repositories. If you don't, or have some trouble installing the package, install the libnlopt-dev Linux Mint package before trying to install the nloptr R package.
