Question

我正在通过以下教程学习c ++，我现在正在使用cMake并且我的glfw库在我的外部文件夹中，但我无法正确链接。这是我的cMake txt文件

cmake_minimum_required(VERSION 2.8.4)
project(dunjun)

set(dunjun_src src/main.cpp)
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin/)
set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin/)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")


set(SOURCE_FILES src/main.cpp) 

include_directories(
    ${PROJECT_SOURCE_DIR}/include
    ${PROJECT_SOURCE_DIR}/external/glfw-3.1/include
)

link_directories(
    ${PROJECT_SOURCE_DIR}/external/glfw-3.1/src
)

add_executable(dunjun ${dunjun_src})

target_link_libraries(dunjun ${PROJECT_SOURCE_DIR}/external/glfw-3.1/src)

它给我的错误如下。

cMake用于链接glfw库的txt文件
