在使用Boost进行C++ python绑定时找不到错误

我正在创建一个基于Qt的应用程序，需要从中运行python代码。为此，我使用Boost.Python。我的错误是：在使用Boost进行C++ python绑定时找不到错误

CMakeFiles/App.dir/main.cpp.o: In function `_GLOBAL__sub_I_main.cpp': 
main.cpp:(.text.startup+0x3): undefined reference to `_Py_NoneStruct' 
collect2: error: ld returned 1 exit status 
make[2]: *** [source/App] Error 1 
make[1]: *** [source/CMakeFiles/App.dir/all] Error 2 
make: *** [all] Error 2 
11:12:47: The process "/usr/local/bin/cmake" exited with code 2. 
Error while building/deploying project App (kit: Desktop Qt 5.7.0 GCC 64bit) 
When executing step "Make"

我相信错误是链接错误，但我不知道如何删除它。我刚刚开始使用cmake，并没有精通它。代码在这里： https://github.com/daemonSlayer/App

我应该在代码中改变它以使其工作？

欢迎来到SO！尝试创建一个[最小，完整，可验证的示例]（http://stackoverflow.com/help/mcve）并在您的问题中包含代码。请勿将您的帖子的关键部分链接到外部网站，因为这些服务可能会倒闭。 –

请向我们展示CMakeLists.txt，然后找出问题会容易得多。 –

我编辑了这个问题并包含了cmake文件。请解释所需的更改。 –

看来你不与链接需要Python库。尝试加入${PYTHON_LIBRARIES$} to target_link_libraries`：

target_link_libraries(${CMAKE_PROJECT_NAME} 
    ${PYTHON_LIBRARIES} 
)
