cmake error and make error

[ygttt]

Hello,

I'm following the commands from this script (https://github.com/IITH-Compilers/P4LLVM)) on a VM with Ubuntu 16.04.7desktop. Can I ask for the assistance to solve this issue?

when I cmake .. :

and when I make -j4:

I use "sudo apt-get install llvm-8"to install llvm
