Verifying HW265Enc

Check whether HW265Enc has been integrated.

1. Configure the dynamic library search path.

   After the decompression, the default path is ~/dependency/. Therefore, you need to manually configure the corresponding environment variable.

   export LD_LIBRARY_PATH=~/dependency/lib:$LD_LIBRARY_PATH

2. Check whether HW265Enc has been integrated.

   ./bin/CloudHw265App -h
