Current behavior?

I built TfLite with -DTFLITE_ENABLE_GPU=ON. I tried to test TfLite with GPU, but the minimal-working C++ example for the GPU from https://www.tensorflow.org/lite/android/delegates/gpu_native does not work under Windows 10 with Visual Studio 2022. I receive the linker error error LNK2001: unresolved external symbol __imp_TfLiteGpuDelegateV2Create. I ran dumpbin on tensorflow-lite.lib and it says a static fuction TfLiteGPUDelegateV2Create does exist. I tried a different Windows 10 machine with Visual Studio 2019, but I receive the same linker error. I got the example working under Ubuntu Linux 23.04 with gcc12 using the same build commands (except from replacing the Windows specifics with Linux specifics of course).

Standalone code to reproduce the issue

Build commands (in Command Prompt):
git clone https://github.com/tensorflow/tensorflow tensorflow_src
mkdir tflite_release_x64
cd tflite_release_x64
cmake -G "Visual Studio 17" -A x64 -DTFLITE_ENABLE_GPU=ON ..\tensorflow_src\tensorflow\lite
cmake --build . -j 16 --config Release

C++ code (https://www.tensorflow.org/lite/android/delegates/gpu_native):
#include "tensorflow/lite/model.h"
#include "tensorflow/lite/interpreter.h"
#include "tensorflow/lite/kernels/register.h"
#include "tensorflow/lite/delegates/gpu/delegate.h"
#include <iostream>

using namespace tflite;

int main() {
    // Set up interpreter.
    auto model = FlatBufferModel::BuildFromFile("C:/Users/bartp/source/lite-model_deeplabv3_1_metadata_2.tflite");
    if (!model) return false;
    ops::builtin::BuiltinOpResolver op_resolver;
    std::unique_ptr<Interpreter> interpreter;
    InterpreterBuilder(*model, op_resolver)(&interpreter);

    auto* delegate = TfLiteGpuDelegateV2Create(/*default options=*/nullptr);

    std::cout << "Done\n";
    return 0;
}
