Mac cmake命令不可用-bash: cmake: command not found

AppledeiMac:~ apple$ cmake --version
-bash: cmake: command not found
AppledeiMac:~ apple$ 

.bash_profile路径：

 # Add Cmake Root to Path
 export CMAKE_ROOT=/Applications/CMake.app/Contents/bin/
 export PATH=$CMAKE_ROOT:$PATH

添加完成后，打开一个新的终端窗口，查看cmake版本号：

AppledeiMac:~ apple$ cmake --version
cmake version 3.12.3

另外也可通过其它方式添加到命令行，打开cmake图形应用：

Tools–How to Install For Command Line Use:

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

由图上内容可知：上面使用的方法其实就是方法1，即 add CMake to the Path：…

方法1. 添加环境变量

见文章开头。

方法2. 安装symlinks

打开终端执行：

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

执行情况：

AppledeiMac:~ apple$  sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install
Password:
Linked: '/usr/local/bin/cmake' -> '/Applications/CMake.app/Contents/bin/cmake'
Linked: '/usr/local/bin/ctest' -> '/Applications/CMake.app/Contents/bin/ctest'
Linked: '/usr/local/bin/cpack' -> '/Applications/CMake.app/Contents/bin/cpack'
Linked: '/usr/local/bin/cmake-gui' -> '/Applications/CMake.app/Contents/bin/cmake-gui'
Linked: '/usr/local/bin/ccmake' -> '/Applications/CMake.app/Contents/bin/ccmake'
AppledeiMac:~ apple$ cmake --version
cmake version 3.12.3

方法3. 安装symlinks到其它路径

其实是方法2的变种，只不过安装到了其它路径。
