mac cmake生成xcode项目工程

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
