Boneheaded question regarding compilation...

[WhatMeWorry]

Huge fan of Mike Shah's YouTube videos regarding D and his latest 
for D conference:

So I installed github desktop app and cloned his Talks repo. 
There is a build command commented out at the top of the main.d 
file which I've been trying to compile, via the command line:

C:\Users\kheas\Documents\Talks\2024\dconf_online\hello_triangle>dmd -g -J. main.d ./glad/gl/*.d -L-L/usr/local/lib -L-lglfw3 -of=prog && ./prog
Error: cannot find input file `.\glad\gl\*.d`
import path[0] = C:\D\dmd2\windows\bin64\..\..\src\phobos
import path[1] = C:\D\dmd2\windows\bin64\..\..\src\druntime\import

I'm using a Windows 11 machine so I thought that maybe the syntax 
was for Linux environment. But replacing all the '/' with '\' did 
not work.
