ImGUI OpenGL3 Linker errors and "Failed to initialize OpenGL loader!" errors

[CrispulentCrisps]

Hello, I'm new to openGL and have been trying to convert my program from an SDL renderer to openGL for a performance boost, as otherwise the program I am making runs at about 15.7FPS

With trying to link the opengl it is fine for the backend implementation, asides from the "Failed to initialize OpenGL loader!" error

I had tried to work glfw, but that was getting linker errors as well with the glfw backend implementation
if (!ImGui_ImplOpenGL3_Init("#version 300")) { cout << glGetError(); }
the cout line is throwing a linker error

any help is appreciated!

Which linker error ?

[CrispulentCrisps]

Error LNK2019 unresolved external symbol __imp_glGetError referenced in function "public: void __cdecl Tracker::Run(void)"

This is the exact error

You need to need with the opengl library. Opengl32.lib on windows.

[CrispulentCrisps]

would this be within the imgui folder itself or elsewhere?

[CrispulentCrisps]

also do you mean a seperate library like GLEW?
and if so then for a music creation program what would be the best option?
