HELP="$0 [<target> ...] [<flag> ...]
 where <target> is:
   clean                      - remove all existing build artifacts and configuration (start over)
   uninstall                  - uninstall libcugraph and cugraph from a prior build/install (see also -n)
   cugraph-pyg                - build the cugraph-pyg Python package
   cugraph-dgl                - build the cugraph-dgl extensions for DGL
   pylibwholegraph            - build the pylibwholegraph Python package
   libwholegraph              - build the libwholegraph library
   tests                      - build the C++ tests
   all                        - build everything
 and <flag> is:
   -v                         - verbose build mode
   -g                         - build for debug
   -n                         - do not install after a successful build (does not affect Python packages)
   --pydevelop                - install the Python packages in editable mode
   --allgpuarch               - build for all supported GPU architectures
   --clean                    - clean an individual target (note: to do a complete rebuild, use the clean target described above)
   -h                         - print this text

 default action (no args) is to build and install 'libwholegraph' then 'pylibwholegraph' then 'cugraph-pyg' then 'cugraph-dgl'
