在https://github.com/ocornut/imgui上它说：No specific build process is required. You can add the .cpp files to your existing project.我尝试使用带有相关.cpp文件的代码块，但是它给了我大约 500+ Undefined Reference to ... errors。imgui.cpp存在的第一个开始|1994|undefined reference to `ImGui::InputText(char const*, char*, unsigned long, int, int (*)(ImGuiInputTextCallbackData*), void*)'。这是我尝试过的以下代码。

#include "imgui.h"



int main()
{

    bool my_tool_active = true;
    float my_color = 0.5;


    // Create a window called "My First Tool", with a menu bar.
    ImGui::Begin("My First Tool", &my_tool_active, ImGuiWindowFlags_MenuBar);
    if (ImGui::BeginMenuBar())
    {
        if (ImGui::BeginMenu("File"))
        {
            if (ImGui::MenuItem("Open..", "Ctrl+O")) { /* Do stuff */ }
            if (ImGui::MenuItem("Save", "Ctrl+S"))   { /* Do stuff */ }
            if (ImGui::MenuItem("Close", "Ctrl+W"))  { my_tool_active = false; }
            ImGui::EndMenu();
        }
        ImGui::EndMenuBar();
    }

    // Edit a color (stored as ~4 floats)
    ImGui::ColorEdit4("Color", &my_color);

    // Plot some values
    const float my_values[] = { 0.2f, 0.1f, 1.0f, 0.5f, 0.9f, 2.2f };
    ImGui::PlotLines("Frame Times", my_values, IM_ARRAYSIZE(my_values));

    // Display contents in a scrolling region
    ImGui::TextColored(ImVec4(1,1,0,1), "Important Stuff");
    ImGui::BeginChild("Scrolling");
    for (int n = 0; n < 50; n++)
        ImGui::Text("%04d: Some text", n);
    ImGui::EndChild();
    ImGui::End();


    return 0;
}

我错过了什么？我在网页上找不到任何链接器命令（根据我的经验，“未定义的引用...”通常是缺少链接器选项的结果）
