linux升级cmake

(仅仅是在我个人电脑上安装通过的例子，帖子只是个人笔记)

1.查看cmake版本

cmake --version

2 卸载过去的版本

sudo apt-get autoremove cmake

最好卸载，不然可能会出现如下错误：

CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
Modules directory not found in
/usr/local/share/cmake-3.5
CMake Error: Error executing cmake::LoadCache(). Aborting.

3.安装需要的版本

1. 下载

cd ~
wget https://cmake.org/files/v3.13/cmake-3.13.2.tar.gz
tar xvf cmake-3.13.2.tar.gz
cd cmake-3.13.2

2.安装

./bootstrap --prefix=/usr
 make
 sudo make install

3.检查

cmake --version
