Plugin DLL Not Loading Anymore

I noticed a similar question here but it was for 4.11 Preview: DLL Not Loading Anymore - Programming & Scripting - Unreal Engine Forums

I have a custom plugin where I include the header files and lib file:
plugins/
plugins/

In my build.cs I’m including these with PublicAdditionalLibraries and PublicIncludePaths respectively. The DLL that’s being loaded is located on the system PATH variable outside of the plugin folder.

This works fine on 4.10 and everything starts up. However, switching it over to 4.11, I get an error on starting up the editor that the dll cannot be found. I could copy over the DLL into the plugin folder to get the editor loading, but that defeats the purpose of having it available in the PATH variable.
