# libpsn00b interface targets
# (C) 2021 spicyjpeg - MPL licensed
# This script creates several "virtual" targets (psn00bsdk_*) that set include
# directories and compiler flags when a target is linked against them. These
# all end up in the autogenerated libpsn00b setup script after installation,
# so this file is only included when building libpsn00b.
# The following targets are currently defined:
# - psn00bsdk_common
# - psn00bsdk_object_lib (same as psn00bsdk_common)
# - psn00bsdk_static_exe
# - psn00bsdk_dynamic_exe
# - psn00bsdk_static_lib
# - psn00bsdk_shared_lib
# - psn00bsdk_module_lib (same as psn00bsdk_shared_lib)
