The CMAKE_CXX_COMPILER:
/home/buildbots/llvm-external-buildbots/workers/ppc64le-sanitizer/sanitizer-ppc64le/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 "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:22 (project):
No CMAKE_ASM_COMPILER could be found.
Tell CMake where to find the compiler by setting either the environment
variable "ASM" or the CMake cache entry CMAKE_ASM_COMPILER to the full path
to the compiler, or to the compiler name if it is in the PATH.
