A possible solution to fix building on Linux

Here is a quick fix to solve issues compiling HIDUE on linux.

Source/HIDUE/HIDUE.Build.cs

```csharp

using System.IO;

if (Target.Platform == UnrealTargetPlatform.Linux) {
File.Copy("/usr/include/libudev.h", ModuleDirectory + "/Private/libudev.h", true);
PublicSystemLibraries.Add("udev");
PublicSystemLibraryPaths.AddRange(new [] {
"/usr/lib" // only this is needed for linking udev
});
}
```

Consider adding this to Linux.md or HIDUE.Build.cs :)

Start with Source/HIDUE/HIDUE.Build.cs and review the proposed Linux-specific build settings. Check Linux.md for the appropriate documentation location, then compile HIDUE on Linux to verify the build fix. Done means the plugin builds successfully on Linux with the required udev dependency.
