# Dusklight Mod SDK entry point
#
# Provides selectable mod service, game ABI, and WebGPU header surfaces without configuring the
# full game tree.
#
# Usage (from a mod project):
#   add_subdirectory(<dusk>/sdk dusk-sdk EXCLUDE_FROM_ALL)
#   add_mod(my_mod FEATURES fmt game webgpu SOURCES ... MOD_JSON mod.json)
#
# On platforms where mods link against the game binary (Windows/Apple/Android), a
# version-independent link stub is downloaded automatically unless DUSK_GAME_EXE is set.
