Description

Orc is currently vendored in the Arrow build.  The CMake vendoring is a headache for downstream packagers (like Anaconda) because when there are build problems, we can't directly patch the vendored package.  We would like to add the option to use external Orc where possible - as it already is for most of the other third-party libraries
