Hello All, Apologies in advance for the beginner question as I'm not versed in cmake.
I'm having difficulties getting Arrow dependencies satisfied with the C++ version (cmake -DARROW_FLIGHT=ON ..). Does anyone have any tips or suggestions that enable them to compile arrow with flight on? I've compiled and installed grpc (and protobuf as a submodule under grpc). I also believe I followed the directions under flight correctly: export PROTOBUF_HOME=/home/t.bisson/git/grpc/third_party/protobuf export LD_LIBRARY_PATH=$PROTOBUF_HOME:/usr/local/lib cmake -DARROW_FLIGHT=ON .. All the libraries are under /usr/local/lib, like libgpr.a. Thanks, Tim The error I'm receiving is this: Added static library dependency zstd_static: /home/t.bisson/git/a/cpp/debug/zstd_ep-install/lib/libzstd.a -- PROTOBUF_HOME: /home/t.bisson/git/grpc/third_party/protobuf -- Found the Protobuf headers: /home/t.bisson/git/grpc/third_party/protobuf/src -- Found the Protobuf shared library: /usr/local/lib/libprotobuf.so -- Found the Protobuf library: /usr/local/lib/libprotobuf.a -- Found the Protoc shared library: /usr/local/lib/libprotoc.so -- Found the Protoc library: /usr/local/lib/libprotoc.a -- Found the Protoc executable: /usr/local/bin/protoc Added static library dependency protobuf_static: /usr/local/lib/libprotobuf.a CMake Error at cmake_modules/ThirdpartyToolchain.cmake:1252 (get_property): get_property could not find TARGET gRPC::gpr.
