如何在clion中运行qt creator演示代码？

Question

要查看代码:我在https://github.com/jaysimon/clion_qtcreator上创建了一个存储库

我成功地在qt creator中制作了一个演示ui，但在clion中使用相同的代码失败了。我得到了这个：

你能帮我用CMake成功地运行它吗？推送请求是最好的。

CMakeList.txt：

cmake_minimum_required(VERSION 3.0)
project(20190314_clion_qt)

set(CMAKE_CXX_STANDARD 11)

set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTORCC ON)
find_package(Qt5Core REQUIRED)
find_package(Qt5Gui REQUIRED)
find_package(Qt5Widgets REQUIRED)

include_directories(./inc)
set(SOURCE_CODE
    src/main.cpp
    src/mainwindow.cpp
    src/deal.cpp)
add_executable(${PROJECT_NAME} ${SOURCE_CODE})

target_link_libraries(${PROJECT_NAME} -pthread Qt5::Core)
target_link_libraries(${PROJECT_NAME} Qt5::Gui)
target_link_libraries(${PROJECT_NAME} Qt5::Widgets)

main.cpp：

#include "mainwindow.h"
#include <QApplication>
#include "deal.h"

int main(int argc, char *argv[])
{
  QApplication a(argc, argv);

  MainWindow w;
  w.show();

  pthread_t tid;
  pthread_create(&tid, NULL, run, NULL);
  //pthread_exit(&tid);

  return a.exec();
}

我解决了它，但我不明白为什么，这里是解决方案，你也可以在github上git它。

把MainWindow.cpp的MainWindow.h MainWindow.ui，所有3个文件放在同一个目录下，就解决了。
