Install the cmake completion script in zsh to complete the cmake command.

I recently tried to use zsh and found that its completion command is quite powerful. However, the completion of the cmake command does not appear in the default 5.0.5, and there are not many articles on zsh completion configuration on the Internet. As a result, I found that there is a functions folder under the zsh installation directory, which contains various completion prompt files starting with _, such as _ SED and _ awk, so after trying to complete the zsh_cmake file on the internet, rename it as _ cmake and place it in the folder (note that the line break of Windows users wastes a lot of time on this, and dos2unix can solve it) restart zsh and enjoy the refreshing effect of completing the cmake command!
