在使用Boost進行C++ python綁定時找不到錯誤

我正在創建一個基於Qt的應用程序，需要從中運行python代碼。爲此，我使用Boost.Python。我的錯誤是：在使用Boost進行C++ python綁定時找不到錯誤

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"

我相信錯誤是鏈接錯誤，但我不知道如何刪除它。我剛剛開始使用cmake，並沒有精通它。代碼在這裏： https://github.com/daemonSlayer/App

我應該在代碼中改變它以使其工作？

歡迎來到SO！嘗試創建一個[最小，完整，可驗證的示例]（http://stackoverflow.com/help/mcve）並在您的問題中包含代碼。請勿將您的帖子的關鍵部分鏈接到外部網站，因爲這些服務可能會倒閉。 –

請向我們展示CMakeLists.txt，然後找出問題會容易得多。 –

我編輯了這個問題幷包含了cmake文件。請解釋所需的更改。 –

看來你不與鏈接需要Python庫。嘗試加入${PYTHON_LIBRARIES$} to target_link_libraries`：

target_link_libraries(${CMAKE_PROJECT_NAME} 
    ${PYTHON_LIBRARIES} 
)
