# GPU has a genuine two-way dependency with Core (Core/System.cpp calls GPU_Init(), while
# all of GPU/ calls back into Core for Memory/Config/CoreTiming/etc). An OBJECT library's
# object files are always included wherever it's consumed rather than being lazily pulled
# from an archive, which sidesteps the GNU ld single-pass archive-ordering problem a normal
# two-way STATIC dependency would hit. Core links this PUBLICLY so consumers of Core get it.
