grpc v1.56.2 support

[jhl07]

Is your feature request related to a problem?
My project needs grpc v1.56.2 cpp library linking with opentelemetry-cpp.

Describe the solution you'd like
I confirmed that the connection works well in opentelemetry-cpp v1.11.0 with MT,MTd build in vs2022 build environment, using grpc v1.39.0.

Describe alternatives you've considered
Compatible with grpc v1.56.2.

Additional context
And if possible, it would be nice to have the option to disable the SSL feature in the WITH_OTLP_GRPC option.

Thanks.

You can use your own prebuilt libraries by set CMAKE_PACKAGE_PATH when building otel-cpp with cmake.

With CMake, opentelemetry-cpp supports a bring-your-own dependency model.

Installing a grpc package to use in the build should work, please let us know if there are specific issues.

As for disabling SSL at build time, there are no such options.

Referring to issue #2163,
I set all profobuf, gRPC, absl cmake find package paths to gRPC v1.56.2 version,
then lib build succeeded and ran well.
Thanks!

@jhl07 Thanks for the update.

Closing this issue then.
