In MacOSX, when drag'n'dropping a document on an SDL app, or double-clicking a document associated with the app, the document(s) are passed to SDL_main() as if they were command line arguments. Otherwise, the command line is always empty and there is no way for the app to recover this information.

# The cpuinfo library target
noinst_LTLIBRARIES = libcpuinfo.la

COMMON_SRCS = 			\
	SDL_cpuinfo.c

libcpuinfo_la_SOURCES = $(COMMON_SRCS)
