This patch let you customize your kernel:
```
{
  "display_name": "C++14-custom",
  "argv": [
      "jupyter-cling-kernel",
      "-f",
      "{connection_file}",
      "--std=c++14"
  ],
  "language": "C++",
  "env": {"CLING_OPTS": "-I<add_directory_to_include_search_path> -L<add_directory_to_library_search_path>"}
}
