##安装环境:ubuntu16.04
## 安装cmake之前需要确认已经安装make、gcc、g++，用make -v | gcc -v | g++ -v可查看是否已经安装，如果没有安装用apt-get安装一下(也可从源码安装)：
sudo apt-get install gcc
sudo apt-get install g++
sudo apt-get install make
## cmake下载：https://cmake.org/download/
wget https://github.com/Kitware/CMake/releases/download/v3.14.3/cmake-3.14.3.zip
wget https://github.com/Kitware/CMake/releases/download/v3.14.3/cmake-3.14.3.tar.gz
注：
源码安装cmake-3.14-3的时候碰到了一些无法解决的错误，贴到了随笔最后，有解决的伙伴可以给个方法
下面直接安装cmake-3.13.4
##cmake解压: tar -zxvf cmake-3.13.4.tar.gz
##cmake安装
step1：./bootstrap
step2:make
step3：make install
step4：cmake --version
如下安装成功：
step5<可选>: make uninstall
##问题记录
1 cmake-3.14.3.zip解压完成后，cd cmake-3.14.3; chmod 775 ./configure; ./configure报错如下：
./configure: 3: exec: /home/guang/3rdTools/cmake-3.14.3/bootstrap: Permission denied
解决：需要首先执行bootstrap(没有进一步研究为什么，网络上给的答案)
chmod 775 bootstrap
./bootstrap
执行./bootstrap报错，还未找到答案
