  Very likely, the build process after this message will fail.

  Simply press Ctrl+C and type
  python -m pip install pybind11
  to fix this. If you don't, the build will continue
  in a few seconds.

  Mako is not installed.
  ---------------------------------------------------------------------------
  That is not a problem, as most of PyOpenCL will be just fine
  without it. Some higher-level parts of pyopencl (such as
  pyopencl.reduction) will not function without the templating engine
  Mako [1] being installed. If you would like this functionality to
  work, you might want to install Mako after you finish
  installing PyOpenCL.

  Simply type
  python -m pip install mako
  either now or after the installation completes to fix this.
