Re: Can someone explain how glfw3.dll gets created?

[Kapps via Digitalmars-d-learn]

Derelict provides bindings to C libraries, and loads them at 
runtime. So glfw3.dll is actually an existing C library (you can 
get it at http://www.glfw.org/download.html), which Derelict 
provides bindings for. Derelict / your code does not generate the 
actual dll.
