1.准备main.cpp文件

#include 

int main()
{

     printf("hello word!");
     return 0;

}

2.编辑CMakeLists.txt

PROJECT(main)

CMAKE_MINIMUM_REQUIRED(VERSION 2.6)

AUX_SOURCE_DIRECTORY(. DIR_SRCS)

ADD_EXECUTABLE(main ${DIR_SRCS})

3.执行命令：

cmake -G "Xcode" .

存在问题：

使用cmake生成xcode的项目

cmake .. -G "Xcode"

结果报如下错误

-- The C compiler identification is unknown

-- The CXX compiler identification is unknown

CMake Error at CMakeLists.txt:2 (project):

 No CMAKE_C_COMPILER could be found.

CMake Error at CMakeLists.txt:2 (project):

 No CMAKE_CXX_COMPILER could be found.

后来使用如下命令解决

sudo xcode-select --switch /Applications/Xcode.app/

重试时记得清空build下的文件
