Linking error even when I initialize imgui and GLEW?

appears that my linking error happens according to those functions
CreateContext, StyleColorsDark, ImGui_ImplGlfw_InitForOpenGL.. and so...

this is the cpp class for more details:
`#include "GLEW/glew.h"
#include "Window/UI/GUI.h"
#include "IMGUI/imgui.h"
#include "IMGUI/backends/imgui_impl_opengl3.h"
#include "IMGUI/backends/imgui_impl_glfw.h"

void GUI::Setup(GLFWwindow* window )
{
glfwInit();
glfwMakeContextCurrent(window);

ImGui::CreateContext();
ImGuiIO& io = ImGui::GetIO(); (void)io;
io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard;     // Enable Keyboard Controls
io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad;      // Enable Gamepad Controls

// Setup Dear ImGui style
ImGui::StyleColorsDark();
//ImGui::StyleColorsLight();

// Setup Platform/Renderer backends
ImGui_ImplGlfw_InitForOpenGL(window, true);
ImGui_ImplOpenGL3_Init("version 330");

}

void GUI::Run(){

ImGui_ImplOpenGL3_NewFrame();

ImGui::NewFrame();
ImGui::Begin("Frame");
ImGui::End();

}

void GUI::End()
{
}
`and those my LIBs

How to fix this error?

Ok, sorry I figured it out.. the problem is all about that I was including imgui to multiple projects without proper linking, because i was including the directory and the sources in the console project and I used those sources within another project "sharedlib project" so that was wrong I think!
So I decided to include the ImGui directory in to just one project then it solved
