Как связать библиотеку stati c GLEW с проектом CMake с использованием MinGW?

Я пытаюсь сделать простой проект треугольника для изучения OpenGL, но я застрял в ошибке компиляции: 

GLFWwindow* initApp() {

  if (!glfwInit()) {
    std::cerr << "Failed to create GLFW context" << std::endl;
    return nullptr;
  }

  glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
  glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 4);
  glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
  glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

  GLFWwindow* window = glfwCreateWindow(1280, 720, "TriangleApp", nullptr, nullptr);
  if (window == nullptr) {
    std::cerr << "Failed to open GLFW window" << std::endl;
    glfwTerminate();
    return nullptr;
  }

  glfwMakeContextCurrent(window);
  glewExperimental = true;
  if (!glewInit()) {
    std::cerr << "Failed to initialize GL libraries" << std::endl;
    return nullptr;
  }

  return window;
}

CMake говорит мне, что есть неопределенная ссылка на glewInit и glewExperimental. Я включил glew.h перед любым заголовком OpenGL, определил GLEW_STATIC в моем проекте CMake и связал glfw3.a и glew32s.lib с целью, используя CMakeLists.txt: 

cmake_minimum_required(VERSION 3.17)

project(TriangleApp)

# GLEW
add_compile_definitions(GLEW_STATIC)
include_directories(libraries/glew/include)
set(GLEW_LINK_LIBRARY ${CMAKE_SOURCE_DIR}/libraries/glew/lib/Release/Win32/glew32s.lib)

# GLFW
include_directories(libraries/glfw/include)
set(GLFW_LINK_LIBRARY ${CMAKE_SOURCE_DIR}/libraries/glfw/lib/libglfw3.a)

# My App
include_directories(headers)
add_executable(TriangleApp source/Main.cpp)

target_link_libraries(TriangleApp
  ${GLEW_LINK_LIBRARY}
  ${GLFW_LINK_LIBRARY})

Вот вывод из Расширение CMake Tasks (vscode):
