我是c++新手cmakelist.txt文件没有给予我Makefile

我不知道如何将编译器更改为G++这是cmake

cmake_minimum_required(VERSION 3.0)
set(CMAKE_C_COMPILER "gcc")
set(CMAKE_CXX_COMPILER "g++")
project(HelLo)
add_executable(Hello main.cpp hello.cpp)

我在windows上,谢谢帮助(我可以用g++和gcc编译,只是cmakefile不起作用)

首先,确保你已经安装了gcc/g++ under Windows(CygWin或MinGW),从你的CMakelists.txt中删除set命令,然后在CygWin/MinGW shell中使用以下命令生成Makefile:

CC=gcc CXX=c++ cmake ..
