# This is an SDK C++ test executable for each supported C++ version.
#
# It will generate multiple targets, each named
# `${target_name}-cxx${cxx_version}`. It does not create a target for
# `${target_name}`.
#
# Parameters
#
#   * cxx_versions
#     - Optional: Compile the C++ tests against these C++ versions.
#     - Type: list(int)
#     - Default: fuchsia_sdk_cxx_supported_versions
#
# See test() for other parameters. Note that `output_name` is specifically
# excluded, because this creates a binary with a different suffix for each
# target.
