Clion 初始化 QT

1.新建项目

2.打开项目，如果出现报错

By not providing “FindQt5.cmake” in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by “Qt5”, but CMake did not find one.

解决方法：安装QT5和对应的cmake软件，然后修改makelist配置文件。

CMake安装位置：

QT安装位置：

3.配置CMake

4.配置QT位置
set(CMAKE_PREFIX_PATH “D:/Library/Qt5.14.2/5.14.2/msvc2017_64/lib/cmake”)
5.配置项目生成平台为64

6.重新加载项目

7.运行

QA
Q：Error copying file “D:/Library/Qt5.14.2/5.14.2/msvc2017_64/lib/cmake/Qt5/…/…/bin/Qt5Cored.dll” to “E:/092-CPP/myqt/cmake-build-debug”.
NMAKE : fatal error U1077: “echo”: 返回代码“0x1”
A：检查路径是否正确，set(CMAKE_PREFIX_PATH “D:/Library/Qt5.14.2/5.14.2/msvc2017_64/lib/cmake”)
