Nick Hortovanyi commented on ARROW-13334:
-----------------------------------------

I experimented on another machine last night. That machine had been upgraded 
over the years probably from Ubuntu 16.04 -> Ubuntu 18.04 -> Ubuntu 20.04 and 
the cmake-gui configuration messages are a lot more detailed with pkg-config 
messages. However I didnt complete a full compile (long story - as I had 
protobufs installed locally which needed upgrading and other packages).

This issue is clearly related to a fresh install of Ubuntu 20.04.2 with the 
versions of clang, cmake etc installed.

I'd also suggest its pointless looking for Findzstd.cmake, FindRE2.cmake and 
FindC-Ares.cmake in the Arrow cmake modules. They will never exist as the 
package maintainers don't produce them.

So no I dont think this issue can be closed. The arrow cmake files just dont 
make sense and/or instructions are required on what to install in retro.

I dont have the time to work it all out at the moment.
