Code using Boost::Compute builds fine on Linux, but not on Windows

I wrote this simple program to learn how to use Boost::Compute.  The program failed to build on Windows, but builds without any errors on Linux.  If I modify the program to only operate on one vector, it works fine.  On Windows I'm using vcpkg to pull in both Boost::Compute as well as the OpenCL SDK and I'm using Visual Studio 2022 to build the project.

#define CL_TARGET_OPENCL_VERSION 300

#include <random>
#include <vector>
#include <boost/compute/core.hpp>
#include <boost/compute/lambda.hpp>
#include <boost/compute/algorithm/transform.hpp>
#include <boost/compute/container/vector.hpp>

std::mt19937 rng{ std::random_device()() };
std::uniform_int_distribution<> dist(1);

namespace compute = boost::compute;
using namespace boost::compute::lambda;

int GetRandomNumber()
{
        return dist(rng);
}

int main(int argc, char* argv[])
{
        const auto device = compute::system::default_device();
        const compute::context context(device);
        compute::command_queue commandQueue(context, device);

        std::vector<int> hostVector1(10000);
        std::vector<int> hostVector2(10000);
        std::vector<int> hostResultVector(10000);
        std::ranges::generate(hostVector1, GetRandomNumber);
        std::ranges::generate(hostVector2, GetRandomNumber);

        compute::vector<int> deviceVector1(hostVector1.size(), context);
        compute::vector<int> deviceVector2(hostVector2.size(), context);
        compute::vector<int> deviceResultVector(hostResultVector.size(), context);

        compute::copy(hostVector1.begin(), hostVector1.end(), deviceVector1.begin(), commandQueue);
        compute::copy(hostVector2.begin(), hostVector2.end(), deviceVector2.begin(), commandQueue);

        transform(deviceVector1.begin(), deviceVector1.end(), deviceVector2.begin(), deviceResultVector.begin(), _1 + _2, commandQueue);

        compute::copy(deviceResultVector.begin(), deviceResultVector.end(), hostResultVector.begin(), commandQueue);

        return 0;
}

Here is the build output:

Is there something I'm missing from my project configuration on Windows?
