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)
   uninstall_cmake_deps - uninstall headers from external dependencies installed by cmake (raft, rmm, cuco, etc.) (see also -n)
   libcugraph           - build libcugraph.so and SG test binaries
   libcugraph_etl       - build libcugraph_etl.so and SG test binaries
   cugraph              - build the cugraph Python package
   pylibcugraph         - build the pylibcugraph Python package
   cpp-mgtests          - build libcugraph and libcugraph_etl MG tests. Builds MPI communicator, adding MPI as a dependency.
   docs                 - build the docs
 and <flag> is:
   -v                   - verbose build mode
   -g                   - build for debug
   -n                   - do not install after a successful build
   --allgpuarch         - build for all supported GPU architectures
   --skip_cpp_tests     - do not build the SG test binaries as part of the libcugraph and libcugraph_etl targets
   -h                   - print this text

 default action (no args) is to build and install 'libcugraph' then 'libcugraph_etl' then 'pylibcugraph' then 'cugraph' then 'docs' targets

 libcugraph build dir is: ${LIBCUGRAPH_BUILD_DIR}

 Set env var LIBCUGRAPH_BUILD_DIR to override libcugraph build dir.
