Answer 1

pip never installs system libraries, it only concerns itself with Python libs.

It seems you need to install zlib before installing cx_Freeze.

Another tool to generate binaries is PyInstaller.

Just do

sudo apt install zlib1g-dev

I was trying to install cx-freeze to convert some python code to an exe but the problem was /usr/bin/ld: cannot find -lz just like you. The file being fetched is compressed (cx_Freeze-5.1.1.tar.gz) so you need zlib. Of course use pip3 for python3.
