Ubuntu SDK错误运行范围示例

我正在学习在Ubuntu 16.04中使用Ubuntu SDK（从PPA安装）为Ubuntu Touch创建一个Scope。

我从模板创建了一个C ++ Scope。当我尝试运行时，出现此错误：

CMAKE_CXX_COMPILER: /usr/bin/arm-linux-gnueabihf-g++ is not a full path to an existing compiler tool. Tell CMake where to find the compiler by setting either the environment variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH.

拜托，我该如何解决？我已经安装了build-essential和g ++软件包。
