Version/Branch of Dear ImGui:

dear imgui, v1.63 WIP

Back-end file/Renderer/OS: (if the question is related to inputs/rendering/build, otherwise delete this section)

Windows 10, 64bit.

My Issue/Question: (please provide context)

Standalone, minimal, complete and verifiable example: (see CONTRIBUTING.md)
When compiling my DLL (which currently doesn't even do anything I have just included the files) I get a LNK1120 Error for unresolved external of _gl3wProcs. I have included imconfig.h, imgui.h, imgui_impl_opengl3.h, imgui_impl_win32.h, imgui_internal.h, stb_rect_pack.h, stb_textedit.h and stb_truetype.h included in my project. I am also using imgui.cpp, imgui_draw.cpp and imgui_impl_opengl3.cpp.

Compiler Output.

You need to link with gl3w.c if you use it in the default opengl3 bindings.
