# iree_run_binary_test()
#
# Creates a test that runs the specified binary with the specified arguments.
#
# Mirrors the bzl function of the same name.
#
# Parameters:
# NAME: name of target
# ARGS: arguments passed to the test binary.
# TEST_BINARY: binary target to run as the test.
# LABELS: Additional labels to apply to the test. The package path is added
#     automatically.
#
# Note: the DATA argument is not supported because CMake doesn't have a good way
# to specify a data dependency for a test.
#
#
# Usage:
# iree_cc_binary(
#   NAME
#     requires_args_to_run
#   ...
# )
# iree_run_binary_test(
#   NAME
#     requires_args_to_run_test
#   ARGS
#    --do-the-right-thing
#   TEST_BINARY
#     ::requires_args_to_run
# )
