qt - 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。我懂了：

[ 16%] Automatic MOC and UIC for target 20190314_clion_qt

你能帮忙用 CMake 成功运行它吗？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)

主.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，但是很困惑为什么，这里是解决方法，你也可以在github上git。

把MainWindow.cpp MainWindow.h MainWindow.ui，3个文件放到同一个目录下，就解决了。
