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.
cpp_vendor(path = ".")
| path | The path to the package root directory |
|---|
The file path to the vendored code (invisibly).
This function vendors cpp11 into your package by copying the cpp11
headers into the inst/include folder of your package and adding
'cpp11 version: XYZ' to the top of the files, where XYZ is the version of
cpp11 currently installed on your machine.
If you choose to vendor the headers you should remove LinkingTo: cpp11 from your DESCRIPTION.
Note: vendoring places the responsibility of updating the code on
you. Bugfixes and new features in cpp11 will not be available for your
code until you run vector_cpp11() again.
