SDK：Software Development kit 软件开发工具包，一般是特定平台的软件包、软件框架、硬件平台、操作系统等建立应用软件的开发工具的集合。
1、资源
Qt开发是要依赖OS提供的SDK
Qt5.3.2使用的是poky1.7
Qt5.6.2使用的是fsl-imx-fb
2、安装
拷贝到 Linux下的/opt 下进行安装，
sh poky-glibc-x86_64-meta-toolchain-qt5-cortexa9hf-vfp-neon-toolchain-1.7_20150530.sh
3、配置qtcreator.sh启动文件
以Qt5.6.2平台为例子，假设安装SDK时的路径为：/opt/fsl-imx-fb/4.1.15-2.0.1，如果你安装的路径与本文不一致，请修改下面配置你的路径
source /opt/fsl-imx-fb/4.1.15-2.0.1/environment-setup-cortexa9hf-neon-poky-linux-gnueabi
# Add environment variables for i.MX6Q

# End
4、添加Qt版本
在Qt-工具-构建和运行-Qt Versions，通过qmake进行添加
如果报错qmake添加不成功，则SDK有问题，或者安装时出错了
5、添加编译器
【注意】编译器的类型要选择Custom，否则有可能编译不生效
6、添加构建套件（kit）
7、hello测试
编写Qt的hello进行测试，能够构建成功，则SDK可以使用
