CMake + QT 环境配置

1.系统环境

系统：win10
QT：5.15.2
IDE: Visual Studio2022

2. CMakeList.txt配置

cmake_minimum_required(VERSION 3.12)
project(demo)

#set(CMAKE_BUILD_TYPE Debug)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_INCLUDE_CURRENT_DIR ON)

################################## 配置QT5环境 #################################
# 自动调用moc，uic，rcc处理qt的扩展部分
