Error C2440 'function': cannot convert from 'GLFWwindow *' to 'nk_glfw_init_state'

I am trying to build the demo in visual studio 2019 and I am getting the following error in main.c at line 107:
ctx = nk_glfw3_init(&glfw, win, NK_GLFW3_INSTALL_CALLBACKS);

Start at main.c line 107 and inspect the declaration and use of nk_glfw3_init, along with the types of glfw, win, and ctx in the Visual Studio 2019 build. Reproduce the C2440 error, then verify that the demo builds without the reported type-conversion diagnostic.
