I did a little research and have found that GIT Bash uses MINGW compilation of GNU tools. 
It uses only selected ones.
You can install the whole distribution of the tools from https://www.msys2.org/ 
and run a command to install Tmux. And then copy some files to installation folder of Git. 
This is what you do:

Install before-mentioned msys2 package and run bash shell
Install tmux using the following command: pacman -S tmux
Go to msys2 directory, in my case it is C:\msys64\usr\bin
