CMake Error at CMakeLists.txt:7 (project):
  The CMAKE_CXX_COMPILER:

    /home/buildroot/buildroot-test/instance-1/output/host/bin/arm-linux-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.
