# Note: In general, prefer to import target_types.gni rather than this file.
# cc_executable.gni and cc_library.gni are both provided by target_types.gni.
#
# cc_library.gni is split out from cc_executable.gni because pw_executable
# templates may need to create pw_source_set targets internally, and can't
# import target_types.gni because it creates a circular import path.
# This template wraps a configurable target type specified by the current
# toolchain to be used for all pw_executable targets. This allows projects to
# stamp out unique build logic for each pw_executable target, such as generating
# .bin files from .elf files, creating token databases, injecting custom data
# as late-bound build steps, and more.
#
# Like pw_source_set, pw_static_library, and pw_shared_library, default configs
# default visibility, and link deps are applied to the target before forwarding
# to the underlying type as specified by pw_build_EXECUTABLE_TARGET_TYPE.
#
# For more information on the features provided by this template, see the full
# docs at https://pigweed.dev/pw_build/?highlight=pw_executable#target-types.
#
# In addition to the arguments supported by a native executable target, this
# template introduces the following arguments:
#
# remove_configs: (optional) A list of configs / config patterns to remove from
# the set of default configs specified by the current toolchain
# configuration.
# remove_public_deps: (optional) A list of targets to remove from the set of
# default public_deps specified by the current toolchain configuration.
