Okay, so I spent about one hour setting up cmake, fltk and libcurl for c++, got all that running now.
I still need to fix the cmake script a bit, but I have a working verison now with this.
I will now add the same curl stuff I had in rust in c++, then work on the gui and all that.
So I will drop rust, and go for c++ instead, much easier for me. Was worth a try in rust, but for now that’s not for me to be honest, I much faster and better in c++.
