Issues with installing Game Porting Toolkit 2.1

I am trying to install the Game Porting Toolkit 2.1 according to the Readme file provided with the toolkit. When I run the following command:

WINEPREFIX=~/my-game-prefix brew --prefix game-porting-toolkit/bin/wine64 winecfg

I get an error message:

zsh: no such file or directory: /usr/local/opt/game-porting-toolkit/bin/wine64

I don't know how to resolve this.

When I type in the command which brew , I get the path /usr/local/bin/brew

What am I doing wrong?
