# This file is used to set the parts that need common settings in the Toolchain

# nuttx_generate_preproces_target

# Description:
# because different toolchains have different preprocessing instructions,
# we define the COMMON preprocessing target here.

# nuttx_generate_preproces_target(
# SOURCE_FILE
# ${single_source_file}
# TARGET_FILE
# ${single_target_output}
# DEPENDS
# ${option_depned_target})
