If i follow the list:
You can add the package with Pkg.clone("
https://github.com/SimonDanisch/GLPlot.jl")
> Pkg.clone("https://github.com/SimonDanisch/GLWindow.jl.git")
> Pkg.clone("https://github.com/SimonDanisch/GLAbstraction.jl.git")
> Pkg.clone("https://github.com/JuliaGL/ModernGL.jl.git")
>
then i get a:
julia> Pkg.clone("https://github.com/SimonDanisch/GLAbstraction.jl.git")
INFO: Cloning GLAbstraction from
https://github.com/SimonDanisch/GLAbstraction.jl.git
INFO: Computing changes...
ERROR: unknown package ModernGL required by GLAbstraction
, so ModernGl should come first.
