Title: [BUILD] Fix the correct make behavior if compiling inside tree

On linux, the output of CP rule was try to write to / which is - of course, forbidden for write.

This solution adds to each part of lib correct pointer to the root of lib where the libs should be written.

Bug found by Kuldeep Singh Dhaka.
