[OpenVino] Plugins not installed properly

Operating system

Windows

Compiler

MSVC

Steps to reproduce the behavior

If you install OpenVino with the default plugins
vcpkg install openvino[core,onnx,tensorflow,pytorch,paddle]:x64-windows

They do not appear to be installed.  Running the example below lists the available plugins, but none are listed.

#include <iostream>
#include <openvino/frontend/manager.hpp>

int main()
{
    // Create a FrontendManager instance
    ov::frontend::FrontEndManager frontend_manager;

    // Get the available frontends
    auto available_frontends = frontend_manager.get_available_front_ends();

    // Print the available frontends
    std::cout << "Available frontends:" << std::endl;
    for (const auto &frontend : available_frontends)
    {
        std::cout << "- " << frontend << std::endl;
    }

    return 0;
}

Expected Output
Available frontends:
- onnx
- tensorflow
- pytorch
- paddle
