If it tells you events.h not found,
like in here:

tmux/tmux#1084

make sure you add $HOME/.local/lib64

LDFLAGS="-static -L$HOME/.local/lib -L$HOME/.local/lib64"

on line 30.

It happened for me.

Thanks for this!

As for me, in case anyone got ncurses not found error at initial attempt, make sure to add CFLAGS="-I$HOME/.local/include -I$HOME/.local/include/ncurses" on line 30.
