Description

Describe your environment
Windows CMake (4.1.1)

Steps to reproduce

cmake -G "Visual Studio 17 2022" -Dprotobuf_ABSL_PROVIDER=package -DOPENTELEMETRY_BUILD_DLL=1 \
-DWITH_OTLP_GRPC=ON -DOPENTELEMETRY_INSTALL=ON \
 -DWITH_OTLP_HTTP=ON -DWITH_OTLP_HTTP_COMPRESSION=ON \ 
-DWITH_EXAMPLES_HTTP=OFF -DWITH_OTLP_HTTP_SSL_PREVIEW=ON \
-DWITH_OTLP_HTTP_SSL_TLS_PREVIEW=ON  -DgRPC_ABSL_PROVIDER=package \
-DgRPC_PROTOBUF_PROVIDER=package  -DABSL_PROPAGATE_CXX_STD=ON \ 
-DWITH_EXAMPLES=OFF -DgRPC_PROVIDER=package -DCMAKE_CXX_FLAGS="/std:c++17 /EHsc"  \
-DCMAKE_CXX_STANDARD=17  -DCMAKE_CXX_STANDARD_REQUIRED=ON  \
-DCMAKE_CXX_EXTENSIONS=OFF -DBUILD_SHARED_LIBS=ON  \
-DCMAKE_PREFIX_PATH="W:\vcpkg\packages\;W:\vcpkg\installed\x64-windows" \
-DWITH_DEPRECATED_SDK_FACTORY=OFF -DCMAKE_POLICY_VERSION_MINIMUM="3.5" \
 -DWITH_BENCHMARK=OFF -DWITH_FUNC_TESTS=OFF  -DBUILD_TESTING=OFF  \ 
-DOPENSSL_ROOT_DIR="W:\vcpkg\packages\openssl_x64-windows" \ 
 -DOPENSSL_USE_STATIC_LIBS=TRUE  ..

DLL is output but seems to be missing the OtlpGrpcExporter?

What is the expected behavior?
That the OTLP exporter would be included in the DLL

What is the actual behavior?

Additional context

Unsure if I'm missing a cmake flag that is required.
