vcpkg port for opentelemetry-cpp is not officially maintained/delivered through this repo (as mentioned here - https://github.com/open-telemetry/opentelemetry-cpp/blob/main/INSTALL.md#using-package-managers) , moving this to discussions. |

I compiiled grpc and follow this guide https://grpc.io/docs/languages/cpp/quickstart/ that is my make file to run the main - the main is an example from otlp_grpc_metrics repository ` CXXFILES = main.cpp clean: |

Oh, I just find you install otel-cpp by vcpkg.Here is a example to use it in cmake build system. test.cppint main () {

Hi, i installed otlp through vcpkg on linux server and used this command to install otlp
./vcpkg install opentelemetry -cpp[otlp,core, Prometheus].
And I tried to work and compile one of the examples on the otlp lib, that located under examples/otlp/grpc_metrics_main
And I got an undefined reference- i don't what I have done wrong.
This my makefile I used.
`CC = g++
TARGET = main
CXXFILES = main.cpp
CXXFLAGS = -O3 -o $(TARGET) -D_GNU_SOURCE -L./ -L./metrics_foo_library -I./ -I./opentelemetry -I./metrics_foo_library
LIBS = -lopentelemetry_common -lopentelemetry_exporter_in_memory -lopentelemetry_exporter_ostream_logs -lopentelemetry_exporter_ostream_span -lopentelemetry_otlp_recordable -lopentelemetry_exporter_ostream_metrics_deprecated -lopentelemetry_http_client_curl -lopentelemetry_exporter_otlp_grpc -lopentelemetry_exporter_otlp_grpc_client -lopentelemetry_exporter_otlp_grpc_log -lopentelemetry_exporter_otlp_http_client -lopentelemetry_exporter_otlp_http -lopentelemetry_exporter_otlp_http_log -lopentelemetry_logs -lopentelemetry_metrics_deprecated -lopentelemetry_proto -lopentelemetry_resources -lopentelemetry_trace -lopentelemetry_version -lprometheus_exporter_deprecated -lpthread -lfoo_library -ldl
