CMake Error at cmake/modules/CheckCompilerVersion.cmake:40 (message):
  Host GCC version should be at least 5.1 because LLVM will soon use new C++
  features which your toolchain version doesn't support.  Your version is
  4.8.5.  You can temporarily opt out using
  LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN, but very soon your toolchain won't be
  supported.
Call Stack (most recent call first):
  cmake/modules/CheckCompilerVersion.cmake:45 (check_compiler_version)
  cmake/config-ix.cmake:13 (include)
