I am compiling the sample [Stabilizer with VisionWorks Graph Mode] which source code in the doc[ VisionWorks Toolkit Reference #### November 01, 2017 | 1.6 Release].
Question 1:demo source code package import error,in version 1.6,there is no NVXIO ,but the cmake also use it,is it a typo?

)

Question2:I use the cmake script to import libnvx.a file,but there is a error,how to fix it ?
