HELP="$0 [clean] [libcuspatial] [cuspatial] [tests] [-v] [-g] [-n] [-h] [-l] [--show_depr_warn]
   clean            - remove all existing build artifacts and configuration (start
                      over)
   libcuspatial     - build the libcuspatial C++ code only
   cuspatial        - build the cuspatial Python package
   tests            - build tests
   -v               - verbose build mode
   -g               - build for debug
   -n               - no install step
   -h               - print this text
   --allgpuarch     - build for all supported GPU architectures
   --show_depr_warn - show cmake deprecation warnings
   default action (no args) is to build and install 'libcuspatial' then
   'cuspatial' targets
