我是 C++ 和 VSCode 的新手，所以这个问题可能有一个非常简单的答案，我只是忽略了。在喜欢 Qt 的 PyQt 变体之后，我尝试使用 Qt 库构建一个应用程序，但我无法从 VSCode 终端启动最简单的应用程序。 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：
令我困惑的是，程序的构建似乎没有错误 - 程序找到 Qt 并且在编译时没有抛出错误。但每当我从 VS Code 终端启动它时，什么也没有发生。没有打印任何声明，也没有启动任何窗口。 如果它有帮助，这是我尝试启动它时的输出：

我将非常感谢任何能够为我指出解决这个问题的方向的人。鉴于没有错误消息，我不知道从哪里开始。如果你们中有人需要更多信息，我很乐意提供。 :)
您好，您还在吗，我在这里也遇到了同样的问题。你能告诉我更多关于你是如何解决的吗？
