VSCode 中的“致命错误：QUdpSocket：没有这样的文件或目录”

Question

我正在努力处理我的 C++ 代码，因为我对大型项目和 CMake 的使用有点陌生。

我遇到了编译问题，我不知道如何解决它，因为网上所有的解决方案都使用 QtCreator，但我使用的是 VS Code。

编译问题

add_executable(main main.cpp)

target_link_libraries(main

    Vision
)

我不知道还需要什么文件。感谢您的帮助！

Answer 1

正如您在

PRIVATE

中使用

target_link_libraries

一样，链接到

Vision

的目标不会继承 Qt 目标的任何设置。要么使用

PUBLIC

，要么您还需要将

main

链接到

Qt6::Network

。
