Vendoring is the act of making your own copy of the 3rd party packages your project is using. It is often used in the go language community.
Details
This function vendors cpp11 and cpp11armadillo into your package by copying the cpp11 and cpp11armadillo headers into the `inst/include` folder and adding 'cpp11 version: XYZ' and 'cpp11armadillo version: XYZ' to the top of the files, where XYZ is the version of cpp11 and cpp11armadillo currently installed on your machine.
Vendoring places the responsibility of updating the code on you. Bugfixes and new features in cpp11 and cpp11armadillo will not be available for your code until you run `cpp_vendor()` again.
Examples
# create a new directory
dir <- tempdir()
dir.create(dir)
#> Warning: '/tmp/RtmpS3D72s' already exists
# vendor the cpp11 headers into the directory
cpp_vendor(dir)
#> Makevars and/or Makevars.win should have a line such as 'PKG_CPPFLAGS = -I../inst/include'
#> DESCRIPTION should not have lines such as 'LinkingTo: cpp11'
