Unresolved external symbol TracerProviderFactory::Create

[nefarius]

Describe your environment

After upgrading from 1.14.x to 1.16.0 and 1.16.1 building the same code fails with a linker error, not finding TracerProviderFactory::Create:

error LNK2001: unresolved external symbol "public: static class std::unique_ptr<class opentelemetry::v1::sdk::logs::LoggerProvider,struct std::default_delete<class opentelemetry::v1::sdk::logs::LoggerProvider> > __cdecl opentelemetry::v1::sdk::logs::LoggerProviderFactory::Create(class std::unique_ptr<class opentelemetry::v1::sdk::logs::LogRecordProcessor,struct std::default_delete<class opentelemetry::v1::sdk::logs::LogRecordProcessor> > &&,class opentelemetry::v1::sdk::resource::Resource const &)" (?Create@LoggerProviderFactory@logs@sdk@v1@opentelemetry@@SA?AV?$unique_ptr@VLoggerProvider@logs@sdk@v1@opentelemetry@@U?$default_delete@VLoggerProvider@logs@sdk@v1@opentelemetry@@@std@@@std@@$$QEAV?$unique_ptr@VLogRecordProcessor@logs@sdk@v1@opentelemetry@@U?$default_delete@VLogRecordProcessor@logs@sdk@v1@opentelemetry@@@std@@@7@AEBVResource@resource@345@@Z)

Steps to reproduce

OTEL CPP is consumed via vcpkg manifest:

{
  ...
  "dependencies": [
    { "name": "abseil" },
    {
      "name": "opentelemetry-cpp",
      "features": [ "otlp-grpc" ]
    }
  ]
}

Project is a simple Windows DLL, OTEL CPP is statically linked.

Used includes:

#define HAVE_ABSEIL // fixes redefinitions of absl types
// gRPC exporter
#include <opentelemetry/exporters/otlp/otlp_grpc_exporter_factory.h>
#include <opentelemetry/exporters/otlp/otlp_grpc_exporter_options.h>

#include <opentelemetry/sdk/trace/processor.h>
#include <opentelemetry/sdk/trace/simple_processor_factory.h>
#include <opentelemetry/sdk/trace/tracer_provider_factory.h>
#include <opentelemetry/sdk/resource/resource.h>
#include <opentelemetry/sdk/resource/semantic_conventions.h>
#include <opentelemetry/trace/provider.h>
#include <opentelemetry/trace/tracer_provider.h>

// gRPC exporter
#include <opentelemetry/exporters/otlp/otlp_grpc_log_record_exporter_factory.h>
#include <opentelemetry/exporters/otlp/otlp_grpc_log_record_exporter_options.h>

#include <opentelemetry/logs/provider.h>
#include <opentelemetry/sdk/common/global_log_handler.h>
#include <opentelemetry/sdk/logs/logger_provider_factory.h>

#include <opentelemetry/sdk/logs/processor.h>
#include <opentelemetry/sdk/logs/simple_log_record_processor_factory.h>

namespace trace     = opentelemetry::trace;
namespace nostd     = opentelemetry::nostd;
namespace otlp      = opentelemetry::exporter::otlp;
namespace logs_sdk  = opentelemetry::sdk::logs;
namespace logs      = opentelemetry::logs;
namespace trace_sdk = opentelemetry::sdk::trace;

Relevant code snippet:

//
// Set up tracing
// 

opentelemetry::sdk::resource::ResourceAttributes resourceAttributes = opentelemetry::sdk::resource::ResourceAttributes{
	{ opentelemetry::sdk::resource::SemanticConventions::kServiceName, TRACER_NAME }
};

opentelemetry::sdk::resource::Resource resource = opentelemetry::sdk::resource::Resource::Create(resourceAttributes);
std::unique_ptr<trace_sdk::SpanExporter> traceExporter = otlp::OtlpGrpcExporterFactory::Create();
std::unique_ptr<trace_sdk::SpanProcessor> traceProcessor = trace_sdk::SimpleSpanProcessorFactory::Create(
	std::move(traceExporter));
std::shared_ptr<trace_sdk::TracerProvider> traceProvider = trace_sdk::TracerProviderFactory::Create(
	std::move(traceProcessor), resource);

std::shared_ptr<trace::TracerProvider> api_provider = traceProvider;
trace::Provider::SetTracerProvider(api_provider);

//
// Set up logger
// 

std::unique_ptr<logs_sdk::LogRecordExporter> loggerExporter = otlp::OtlpGrpcLogRecordExporterFactory::Create();
std::unique_ptr<logs_sdk::LogRecordProcessor> loggerProcessor = logs_sdk::SimpleLogRecordProcessorFactory::Create(
	std::move(loggerExporter));
std::shared_ptr<logs_sdk::LoggerProvider> loggerProvider = logs_sdk::LoggerProviderFactory::Create(
	std::move(loggerProcessor), resource);

std::shared_ptr<logs::LoggerProvider> l_api_provider = loggerProvider;
logs::Provider::SetLoggerProvider(l_api_provider); 

What is the expected behavior?

Solution should build fine, I applied the migration path mentioned here but nothing changes.

What is the actual behavior?

Additional context

Neither the v1.14.x compatible nor the upgraded (factory deprecation) variant works under 1.16.x, I skipped 1.15 so IDK the behavior there.
