用VSCODE＆amp; C＆＃x2B;＆＃x2B;

Question

我是C ++以及VSCODE的新手，因此这个问题可能会有一个非常简单的答案，我只是在忽略。在喜欢其PYQT变体后，我正在尝试使用QT库来构建一个应用程序，但是我无法获得从VSCODE终端启动的最简单的应用程序。 这是我尝试构建和运行的程序：

// main.cpp - I copied and pasted the Qt documentation example after I had Qt import issues
// (which I have since resolved)
#include <iostream>
#include <QApplication>
#include <QPushButton>

int main(int argc, char *argv[])
{
    std::cout << "So far";
    QApplication qga (argc, argv);
    QPushButton btn ("ayo");
    btn.show();
    return qga.exec();
}

这是构建应用程序的cmakelists.txt文件：

cmake_minimum_required(VERSION 3.16)
project(trial VERSION 0.1.0)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)


set(CMAKE_PREFIX_PATH "C:/Qt/6.3.0/mingw_64/")
set(CMAKE_INCLUDE_CURRENT_DIR ON)
find_package(Qt6 REQUIRED COMPONENTS Widgets Gui Core)

qt_standard_project_setup()


add_executable(trial main.cpp)

target_link_libraries(trial PRIVATE Qt6::Widgets Qt6::Gui Qt6::Core)
include(CPack)

这些是我正在使用的组件：

• VS Code 2017
• CMake（扩展）
• CMAKE工具（扩展）
• QT Tools（扩展）QT Tools（扩展）
• GCC 8.1。 0x86_64-W64-MINGW32编译器
• QT 6.3.0

令我感到困惑的是，该程序似乎没有错误 - 该程序在编译时找到QT并没有抛出任何错误。但是，每当我从VS代码终端启动它时，什么也不会发生。没有打印任何声明，也没有启动任何窗口。 如果它有所帮助，这是我尝试启动它的输出：

我将非常感谢可以将我指向解决此问题的任何人。鉴于没有错误消息，所以我对从哪里开始失去了我的迷路。如果你们中的任何人都需要更多信息，我会很乐意为其提供。 :)
