linux下安装cmake

1.在官网下载对应版本的包
https://cmake.org/download/
注意32位和64 位一定要区分开

2.如果是下载的含有source标签的则是源代码文件，需要自己编译，如果下载的是Binary distributions对应的则是已经编译好的版本，只需要添加环境变量就行。

3.一下以安装源文件版本为例
下载源文件后解压，进入文件目录

sudo ./bootstrap

遇到

---------------------------------------------
CMake 3.10.0, Copyright 2000-2017 Kitware, Inc. and Contributors
C compiler on this system is: cc  
---------------------------------------------
Error when bootstrapping CMake:
Cannot find a C++ compiler supporting C++11 on this system.
Please specify one using environment variable CXX.
See cmake_bootstrap.log for compilers attempted.
---------------------------------------------
Log of errors: /home/javascript/下载/cmake-3.10.0/Bootstrap.cmk/cmake_bootstrap.log
---------------------------------------------

原来是没有装c++的编译器

ubuntu： apt-get install gcc g++
CentOS：yum install gcc gcc-c++

4.再次执行sudo ./bootstrap,成功结果如下

---------------------------------------------
CMake has bootstrapped.  Now run make.

5.执行

sudo make

编译完成部分结果如下：

[ 99%] Linking C executable pseudo_tidy
[ 99%] Built target pseudo_tidy
Scanning dependencies of target pseudo_cppcheck
[ 99%] Building C object Tests/RunCMake/CMakeFiles/pseudo_cppcheck.dir/pseudo_cppcheck.c.o
[ 99%] Linking C executable pseudo_cppcheck
[ 99%] Built target pseudo_cppcheck
Scanning dependencies of target foo
[100%] Building CXX object Tests/FindPackageModeMakefileTest/CMakeFiles/foo.dir/foo.cpp.o
[100%] Linking CXX static library libfoo.a
[100%] Built target foo

6.执行

sudo make install

执行完成之后输入

cmake --version

查看版本和下载的是否一致,我下载的3.10.0

cmake --version
cmake version 3.10.0

安装完成
