Cannot find the header file cl_viv_vx_ext.h.

在x86_64的机器上编译运行，运行命令：

./_deps/tensorflow-build/tools/benchmark/benchmark_model --external_delegate_path=./libvx_delegate.so --graph=../../inception5h/mobilenet_v1_0.25_128_quant.tflite

mobilenet_v1_0.25_128_quant.tflite 是从这里下载的：
https://storage.googleapis.com/download.tensorflow.org/models/mobilenet_v1_2018_08_02/mobilenet_v1_0.25_128_quant.tgz

当你看到 Cannot find the header file cl_viv_vx_ext.h. 这个错误时，表示你没有设置对VIVANTE_SDK_DIR这个环境变量，这个环境变量要指向我们驱动的sdk root目录，比如TIM-vx 里面的prebuilt x86目录

感谢回复，设置这个环境变量后正常了。
