CMake Error at cmake/modules/CheckCompilerVersion.cmake:44 (message):
  Host GCC version should be at least 7.1 because LLVM will soon use new C++
  features which your toolchain version doesn't support.  Your version is
  6.3.0.  You can temporarily opt out using
  LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN, but very soon your toolchain won't be
  supported.
