vscode配置cmake插件，进行debug

配置launch.json文件如下：

{    // Use IntelliSense to learn about possible attributes.    // Hover to view descriptions of existing attributes.    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387    "version": "0.2.0",    "configurations": [                {            "name": "(gdb) Launch",            "type": "cppdbg",            "request": "launch",            // Resolved by CMake Tools:            "program": "${command:cmake.launchTargetPath}",            "args": [],            "stopAtEntry": false,            "cwd": "${workspaceFolder}",            "environment": [],            "externalConsole": true,            "MIMode": "gdb",            "setupCommands": [                {                    "description": "Enable pretty-printing for gdb",                    "text": "-enable-pretty-printing",                    "ignoreFailures": true                }            ]        }    ]}

运行vscode左下角的角标，如下

依次运行，cmake，build，debug

其中将[all]切换为想要进行debug的可执行文件

点击debug(虫子型图标)，会提示`Target debugging is no longer supported with the legacy driver`

解决方法：

查看自己的cmake版本，ubuntu16.04 默认安装的cmake为3.5.1版本

vscode的cmake插件要求cmake>=3.7.1

更新自己的cmake，重新打开vscode，依次运行，cmake，build，debug即可

附cmake更新教程，

1. 卸载已经安装的旧版的CMake[非必需]

apt-get autoremove cmake

2. 文件下载解压：

wget https://cmake.org/files/v3.9/cmake-3.9.1-Linux-x86_64.tar.gz

解压：

tar zxvf cmake-3.9.1-Linux-x86_64.tar.gz

查看解压后目录:

tree -L 2 cmake-3.9.1-Linux-x86_64cmake-3.9.1-Linux-x86_64├── bin│   ├── ccmake│   ├── cmake│   ├── cmake-gui│   ├── cpack│   └── ctest├── doc│   └── cmake├── man│   ├── man1│   └── man7└── share    ├── aclocal    ├── applications    ├── cmake-3.9    ├── icons    └── mime12 directories, 5 files

bin下面有各种cmake家族的产品程序.

3. 创建软链接

注: 文件路径是可以指定的, 一般选择在/opt 或 /usr 路径下, 这里选择/opt

mv cmake-3.9.1-Linux-x86_64 /opt/cmake-3.9.1ln -sf /opt/cmake-3.9.1/bin/*  /usr/bin/

然后执行命令检查一下：

>>>cmake --versioncmake version 3.9.1CMake suite maintained and supported by Kitware (kitware.com/cmake).>>>>>>cmake-gui

OK。现在cmake最新版本安装成功。 

CMake的官方书籍很贵，并且总是晚于实际最新版本，如果想看最新的文档，建议参考：
