Mac安装cmake实践

1、下载

去cmake官网下载对应版本的binaries or source code archives。

我电脑：Apple M1 Pro、macOS：版本13.0.1 (22A400)，下载的cmake-3.26.0-rc2-macos-universal.dmg版本

2、安装

点击dmg拖拽安装后实验失败

cmake .. 
zsh: command not found: cmake

于是在电脑Launchpad(启动台)找到CMake图标，点击启动

点击Tools，选择How to Install For Command Line Use

给了三种安装方式：

文字版本：

One may add CMake to the PATH:

 PATH="/Applications/CMake.app/Contents/bin":"$PATH"

Or, to install symlinks to '/usr/local/bin', run:

 sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install

Or, to install symlinks to another directory, run:

 sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install=/path/to/bin

于是在终端执行了

sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install

完成安装

3、验证

命令行验证版本号：

~ % cmake --version
cmake version 3.26.0-rc2

CMake suite maintained and supported by Kitware (kitware.com/cmake).

写一个helloworld.cpp

#include 
using namespace std;
 
int main() 
{
    cout << "Hello, World!";
    return 0;
}

CMakeList.txt

cmake_minimum_required(VERSION 3.0)
project(HelloWord)

add_executable(hello_world helloword.cpp)

终端运行：

% mkdir build && cd build
build % cmake .. && make -j8
build % ./hello_world 
Hello, World!%
