# Add a build-and-test CTest.
# - full_test_name_var will be set to the full name of the test.
# - name_prefix is the prefix of the test's name (e.g. `cccl.test.cmake`)
# - subdir is the relative path to the test project directory.
# - test_id is used to generate a unique name for this test, allowing the
#   subdir to be reused.
# - Any additional args will be passed to the project configure step.
