The right way to link to nnpack

[wangkuiyi]

In our root CMakeLists.txt file, we have

Paddle/CMakeLists.txt

Lines 177 to 180 in d883547

	if(USE_NNPACK)
	include(external/nnpack)
	list(APPEND EXTERNAL_LIBS ${NNPACK_LIBS})
	endif(USE_NNPACK)

It uses the special variable EXTERNAL_LIBS.

@hedaoyuan I am wondering why glog and gflags and many other third-party libraries don't need to be added to EXTERNAL_LIBS, but nnpack has to be?

Could @gangliao have a look at this issue as well? Thanks!

glog and gflags and many other third-party libraries are also included.

Paddle/CMakeLists.txt

Lines 156 to 163 in d883547

	set(EXTERNAL_LIBS
	${GFLAGS_LIBRARIES}
	${GLOG_LIBRARIES}
	${CBLAS_LIBRARIES}
	${PROTOBUF_LIBRARY}
	${ZLIB_LIBRARIES}
	${PYTHON_LIBRARIES}
	)

@gangliao Got it. Thanks. I am closing this issue.
