cmakelist添加Qt5的network模块无效

[十秒耿直拆包选手]

如题。我使用clion。按照网上教程，在find_package和target_link_libraries中添加Network，但是项目调用不到network模块中的类，例如QTcpServer。

cmakelist如下：

cmake_minimum_required(VERSION 3.27)
project(CppGuiProgramming)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)

set(CMAKE_PREFIX_PATH "C:/ProgramFiles/Qt/5.15.2/msvc2019_64/lib/cmake")

find_package(Qt5 COMPONENTS
    Core
    Gui
    Widgets
    Network
    REQUIRED)

# 编码设置。

add_compile_options("$<$<CXX_COMPILER_ID:MSVC>:/utf-8>")
