---------------------------------------------------------------
Hello, I have an MVP of this working. Being able to read parquet has decreased
the latency in my project by 60%. I would love to be able to contribute back.
I can contribute the Rcpp code to load parquet into a tibble, but I have little
experience with producing a configure file and pkg-config. One thing I need
help with is producing the configure file in
[https://github.com/apache/arrow/blob/master/r/configure|https://github.com/apache/arrow/blob/master/r/configure.]
It references pkg-config to figure out how to link to the c++ arrow library. I
believe it references information in
[https://github.com/apache/arrow/blob/master/cpp/src/arrow/arrow.pc.in.]
However, in order for the R library to read parquet we need to link to both
-lparquet and -larrow. To get this to work on my application I hardcoded the
configure file, but I would like to learn how to do this properly. I sense that
arrow and parquet are organized as separate projects in the arrow repository,
how should I produce a configure that will link to both?
