Answer 1

Whenever you find yourself missing some tool you don't know where is, one way of finding it could be by using apt-cache search.

apt-cache search 7z

This will show you a short list where one of the entries are:

p7zip - 7z file archiver with high compression ratio

So to solve your primary question you'd run:

apt-get install p7zip

You'll get CMake and autoreconf by installing the cmake and autoconf packages:

apt-get install cmake autoconf

Answer 2

Just install the missing tools:

apt-get update
apt-get install cmake autoconf p7zip-full

Or, if you are not root,

sudo apt-get update
sudo apt-get install cmake autoconf p7zip-full
