Ubuntu14.04安装CMake3.0.2

1、去网址下载 http://www.cmake.org/download/

Platform	Files
Unix/Linux Source (has \n line feeds)	cmake-3.0.2.tar.gz

2、把 cmake-3.0.2.tar.gz放到想放到的目录( Cmake的安装路径默认在：/usr/local/中)，然后解压，解压命令 sudo  tar -zxvf cmake-3.0.2.tar.gz

3、进入cmake-3.0.2  进入命令 cd cmake-3.0.2

4、执行 sudo ./bootstrap

如果出现如下错误提示

Error when bootstrapping CMake Cannot find appropriate C++ compiler on this system Please specify one using environment variable CXX…

则执行

sudo apt-get install  build-essential 

安装gcc-c++，然后再从新执行步骤4

5、执行sudo make 

6、执行 sudo make install

7、执行 cmake --version

如果输出

cmake version 3.0.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).

则证明安装成功
