install

Many platforms provide pre-built packages of tmux (apt install tmux), although these are often out of date Repo

# run packages
apt install libevent ncurses

# buiold packages
apt install libevent-dev ncurses-dev build-essential bison pkg-config

# build
tar -zxf tmux-*.tar.gz
cd tmux-*/
./configure
make && sudo make install

To install elsewhere add --prefix to configure, for example for /usr add --prefix=/usr.
