Hi Tim,
This part of the codebase is a good ways from production-ready -- we aren't
running the tests in CI for example. I put in enough hacks to be able to
build using a local gRPC install that used CMake. Almost certainly a number
of changes to FindGRPC.cmake will need to be made to get things working for
more general installs of the libraries.
The gRPC build system is a bit of a pain because it may install all of its
third-party dependencies, possibly causing conflicts with other parts of
the Arrow build system.
The Flight RPC project is definitely a priority for 2019 so would be glad
to have you involved, and we can try to help resolve the immediate build
issues.
