## cub_add_example
#
# Add an example executable and register it with ctest.
#
# target_name_var: Variable name to overwrite with the name of the example
#   target. Useful for post-processing target information per-backend.
# example_name: The name of the example minus "<config_prefix>.example." For
#   instance, examples/vector.cu will be "vector", and examples/cuda/copy.cu
#   would be "cuda.copy".
# example_src: The source file that implements the example.
# cub_target: The reference cub target with configuration information.
