GLFW库的链接错误（未定义引用）

问：

我正在尝试学习 OpenGL，但我有点坚持链接必要的库。注意：我使用 WSL，尝试使用 CMake 和 mingw-w64（编译器）为 Windows 构建可执行文件。i686-w64-mingw32-g++

这是我的文件夹结构：

build/
    CMakeCache.txt
    etc.
lib/
    include/
        GLFW/
            glfw3.h
            glfw3native.h
    libglfw3.a
src/
    main.cpp
.gitignore
CMakeLists.txt

我想编译该文件，并将其与 libglfw3.a（来自目录的 64 位 Windows 预编译二进制文件）链接main.cpplib-mingw-w64

My 是 GLFW 网站的示例代码：https://www.glfw.org/documentation.htmlmain.cpp

#include <GLFW/glfw3.h>

int main(void)
{
    GLFWwindow* window;

    /* Initialize the library */
    if (!glfwInit())
        return -1;

    /* Create a windowed mode window and its OpenGL context */
    window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);
    if (!window)
    {
        glfwTerminate();
        return -1;
    }

    /* Make the window's context current */
    glfwMakeContextCurrent(window);

    /* Loop until the user closes the window */
    while (!glfwWindowShouldClose(window))
    {
        /* Render here */
        glClear(GL_COLOR_BUFFER_BIT);

        /* Swap front and back buffers */
        glfwSwapBuffers(window);

        /* Poll for and process events */
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

CMakeLists.txt:

cmake_minimum_required(VERSION 3.18.4)
project(opengl-triangle)

add_executable(triangle src/main.cpp)

target_include_directories(triangle PUBLIC lib/include)

find_library(
    GLFW_LIB
    NAMES glfw3
    HINTS "${CMAKE_SOURCE_DIR}/lib"
    NO_DEFAULT_PATH
)
if(NOT GLFW_LIB)
  message(FATAL_ERROR "GLFW library not found")
endif()

target_link_libraries(
    triangle
    ${GLFW_LIB}
)

当我尝试构建我的项目时，我得到这个：

如果我理解正确，这是一个链接错误。但是，我用 .为什么会有s？CMakeLists.txttarget_link_librariesundefined reference

我尝试在没有 WSL 的情况下使用 MinGW 构建相同的内容，尝试将库与完整路径链接：。尝试了这个答案（包装在 .结果是一样的。target_link_libraries(triangle "/mnt/d/Programming/Projects/opengl-test/lib/libglfw3.a")#includeextern "C"

我还尝试使用不同的编译器（），并更改了：cmake .. -D CMAKE_C_COMPILER=x86_64-w64-mingw32-gcc -D CMAKE_CXX_COMPILER=x86_64-w64-mingw32-g++undefined reference
