How can I avoid rebuilding 15GB-8hr long PCL library every time I move to a new identical HW?

Question

I am using Jetson TX2 boards for my work with PCL and GPU. Since, GPU sub-systems are not available on any apt-repos, I am told to build them from source every time I move to a new system.

Since all HW is identical,how can I just copy the same PCL library built initially on other systems to new system and start using directly? I kept getting the CMAKE error:

This directory is not where CMakeCache file was generated. 

What is the way around this?
