PolygonDLL requires vcpkg to manage package installation such with libcurl, detours, and rapidjson. Here's a quick way to install vcpkg;

> cd <path where vcpkg should be kept; such as C:\vcpkg>
> git clone https://github.com/microsoft/vcpkg
> .\vcpkg\bootstrap-vcpkg.bat
> .\vcpkg\vcpkg integrate install
> .\vcpkg\vcpkg integrate project

PolygonDLL only builds under Win32 for x86 architecture.

The DLL is imported with StudPE under the import function name. Otherwise, the DLL should be imported into the executable via VMProtect.

Several preprocessor flags are available that modify how the DLL operates. They are specific to the executable being compiled for.
