Building a project with code from the voronoi fails in Visual Studio

[etonishev]

Steps to reproduce:

1. Clone the code
2. Create a new console project in the Visual Studio
3. Add a new cpp file and put the following code there:

#include <iostream>
#include "jc_voronoi.h"

int main()
{
    return 0;
}

4. Go to Solution Explorer -> Project Properties -> C/C++ -> General
5. Add a path to the voronoi\src folder (of the cloned code) in Additional Include Directories property.
6. Apply
7. Try to build Solution by using hotkey Ctrl + B

As the result you will get the following error:

error C2526: 'jcv_delauney_begin': C linkage function cannot return C++ class 'jcv_delauneyiter' message : see declaration of 'jcv_delauneyiter'

My environment: Microsoft Visual Studio Professional 2022 (64-bit) - Version 17.4.4

I try doing the same at home in Visual Studio Community 2022 (64-bit) - Version 17.4.3 and the project was built successfully.

Upd: Visual Studio Community 2022 (64-bit) - Version 17.4.4 builds the project without any problems too.

Thanks! I'll try to fix this warning today. It was an oversight on my part. It should be easy to fix by passing in a pointer to the iterator when creating it.

@JCash could you explain why it happens, please? I can't find a good article about this problem in VS.
