cross compilation installation on target

Question

I have cross compile some libraries on an virtual machine ubuntu 18.04 (VMware) running on windows 10 on an x86-64 machine. I have tried installing the build onto host(VMware). The program seem to compile well

Now I want to install them onto the target device. Now I have some questions

1. To copy over the build content from the host to the target, I would just need to copy the contents in where i defined the "prefix" in my host directory to where the same directory exists in the target?
2. Can I just copied over the affected libraries aka from host "/opt/fsl-imx-xwayland/4.14-sumo/sysroots/aarch64-poky-linux/usr/lib" to the target "/usr/lib"
3. Do I have to create my sym link to link to new libraries if some libraries is being updated?

Thanks
