  The cmake-policies(7) manual explains that the OLD behaviors of all

CMake Error at CMakeLists.txt:17 (project):
  The CMAKE_C_COMPILER:

    /home/b/sanitizer-x86_64-linux/build/build_default/bin/clang

  is not a full path to an existing compiler tool.

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.

  The CMAKE_CXX_COMPILER:

    /home/b/sanitizer-x86_64-linux/build/build_default/bin/clang++

  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.

CMake Error at CMakeLists.txt:17 (project):
  No CMAKE_ASM_COMPILER could be found.

  Tell CMake where to find the compiler by setting either the environment
