c++ - Glew 未定义引用链接错误

Question

当我尝试在 CLion 中构建我的项目时，我遇到了来自 cmake 的链接错误。我已经尝试过其他线程所说的:将 opengl 放在最后，将 glu 放在第一位，更改我的 include 的顺序并设置 cmake 选项 GLEW_STATIC 但他们都没有修复它甚至给出不同的错误。

我使用了专门为 mingw32 编译的 glew(来自 https://julianibarz.wordpress.com/2010/05/12/glew-1-5-4-mingw32/ )并且我自己编译了 GLEW 但我仍然遇到同样的问题..

这是我的 CMake 文件:

cmake_minimum_required(VERSION 3.2)
project(3D_prototyping)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
find_package (OpenGL REQUIRED)

if (WIN32)
else (WIN32)
  find_package (glfw3 REQUIRED)
endif (WIN32)

set(SOURCE_FILES main.cpp)

add_executable(3D_prototyping ${SOURCE_FILES})
  target_link_libraries (3D_prototyping
          ${GLFW3_LIBRARY}
          ${OPENGL_LIBRARIES}
          ${GLEW_LIBRARY}
          ${COCOA_LIBRARY} ${COREVID_LIBRARY} ${IOKIT_LIBRARY})
if (WIN32)
  target_link_libraries (3D_prototyping
          ${OPENGL_LIBRARIES} glfw3 glu32 opengl32)
endif (WIN32)

这是我遇到的错误:

已修复。

在某个地方，我得到了 glew 使用的 glu32，而不是我编译的 Windows 版本。添加了对 glew32 的引用，它工作正常。
