Antoine Pitrou commented on ARROW-11460:
----------------------------------------

By "if present", do you mean detect them at runtime rather than compile-time?

> We vendor/bundle all compression libraries and have them disabled in the default build. This is reliable, but it would be nice to use system libraries if they're present. 
> It's not as simple as setting {{ARROW_DEPENDENCY_SOURCE=AUTO}} because we have to know if we're using them in order to set the right `-lwhatever` flags in the R package build. Maybe these can be determined from the C++ build/cmake output rather than detected outside the build (but this may require ARROW-6312).
