[Possible bug] Symlinks creation doesn't take in count CMAKE_INSTALL_PREFIX

[nemothenoone]

Describe the bug
A CMAKE_INSTALL_PREFIX pre-configured installation fails with:

CMake Error at zkllvm/cmake/create-symlinks.cmake:12 (file): 
file failed to create symbolic link '/usr/bin/assigner': Operation not permitted
Call Stack (most recent call first): cmake_install.cmake:45 (include)

This means that the installation was only supposed to be done with root privileges, which is not always true.

To Reproduce
How to reproduce the behavior:

cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=~/zkllvm/relwithdebinfo -DCMAKE_BUILD_TYPE=RelWithDebInfo -S zkllvm -B ~/zkllvm/relwithdebinfo && make -j$(nproc) install

Expected behavior
Installation was supposed to succeed without requesting for root privileges

A fix worked partially, but unfortunately, still not fixed.
