-- The cxx compiler identification is unknown CMake Error at CMakeLists.txt:12 (project) : No CMAKE_CXX_COMPILER could be found. Tell CNake where to find the compiler by setting either the environment variable "Cxx" or the CNake cache entry'CMAKE_CXX_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH. -- Configuring incomplete,errors occurred !
解决办法
sudo apt install -y build-essential
build-essential有什么作用
Ubuntu缺省情况下，并没有提供C/C++的编译环境，因此还需要手动安装。但是如果单独安装gcc以及g++比较麻烦，所以Ubuntu提供了一个build-essential软件包，他集成了gcc以及g++所需要的环境
