CMAKE build failure because grpc

[dimitrisfinas]

I tried to build opentelemetry-cpp (v1.2.0) with cmake following instructions: https://github.com/open-telemetry/opentelemetry-cpp/blob/main/INSTALL.md and encountered error “CMake Error at /usr/local/lib/lib/cmake/grpc/gRPCConfig.cmake:13 (include):
include could not find load file:
/usr/local/lib/lib/cmake/grpc/gRPCTargets.cmake”.

I think I followed all prerequisites, I am on ubuntu: bionic (18.04) and I am building grpc 1.39.1 on same container before building opentelemetry.
Did you already encounter this issue? Any solution or workaround it?

This looks to be the problem with gRPC installation. Are you able to build a simple (non-opentelemetry) client-server example after installation as steps here

indeed, grpc is complex to build due to its dependencies. I found a solution to this issue by using another docker image (as I used multi-stage build in docker). see #1229 formore details

The full answer to this issue was provided by using docker image and scripts setup_grpc.sh as stated in discussion #1229
