Mac更新完系统，通过命令行准备编译C++文件时，报错：
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools) 解决方法：更新xcode，在命令行运行
xcode-select --install 安装完，重新编译，报错：
CMake Error at /opt/homebrew/Cellar/cmake/3.25.0/share/cmake/Modules/CMakeTestCCompiler.cmake:70 (message): The C compiler "/Library/Developer/CommandLineTools/usr/bin/cc" is not able to compile a simple test program.
