Wes McKinney edited comment on ARROW-5488 at 6/3/19 3:06 PM:
-------------------------------------------------------------

One possibility is to bundle the Arrow header files with the CRAN package and build against them, but do not include {{libarrow}} and {{libparquet}} when linking. When the library is loaded, the libraries must be loaded in-process via {{dlopen}} before loading the Rcpp extensions. The C++ libraries can be installed then after the fact

> As a way to get to CRAN, we need some way for the package still compile and install and test (although do nothing useful) even when the c++ lib is not available.
