[jira] [Created] (ARROW-11938) [R] Enable R build process to find locally built C++ library on Windows

Ian Cook created ARROW-11938:
--------------------------------

             Summary: [R] Enable R build process to find locally built C++ library on Windows
                 Key: ARROW-11938
                 URL: https://issues.apache.org/jira/browse/ARROW-11938
             Project: Apache Arrow
          Issue Type: Improvement
          Components: R
            Reporter: Ian Cook


Currently, {{configure.win}} and {{tools/winlibs.R}} have two ways of finding the Arrow C++ library:
 # If {{RWINLIB_LOCAL}} is set, it gets it from that zip file
 # If not, it downloads it

Enable and document a third option for the case when the C++ library has been built locally. This will enable R package developers using Windows machines to make changes to code in the C++ library, build and install it, and then build the R package using it.
