Throw DllNotFoundException: libnuitrack when build

If build allModuleScene or different scene, program doesn’t work.
It only happens build file.
When I build unity 2017, it works well but now I build it 5.5.2.
Why it is?

It was just my mistake. sorry.
If change architecture to x86_64 in build setting, it works!

The sdk libraries are somewhat specific in the software platforms they are compiled against - make sure you are compiling against the correct system.
