# An executable that can be used in CTS.
#
# An equivalent to the built-in executable, but ensures dependencies are allowed
# in CTS.
#
# Example:
# ```
# cts_executable("my-test") {
#   deps = [ "//zircon/public/lib/zxtest" ]
#   sources = [ "//sdk/cts/tests/my_test/my_test.cc" ]
#   testonly = true
# }
# ```
#
# Parameters
#   sources (required)
#     List of files to create an executable from.
#     Type: list(labels)
