cmake编译出错：No CMAKE_CXX_COMPILER could be found.

错误类似：

-- The CXX compiler identification is unknown
-- The C compiler identification is GNU 8.3.0
CMake Error at CMakeLists.txt:99 (enable_language):
  No CMAKE_CXX_COMPILER could be found.
 
  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.      

解决办法：

sudo apt install -y build-essential
