You’re looking at the new IDE right there. It’s not ready for people to clone just yet. I’ll prepare a version you can build by the end of the week.
Until then, the IDE that we current have is in the openmv repo under usr. That’s what all the docs are talking about.
As for the new IDE. It’s built on top of qt-creator which is GPL. We’re suing Qt Creator as a base because of its excellent text editor and cross platform installation environment. I spent 2 years learning how Qt Creator worked on a previous project and now I’m applying that knowledge for OpenMV.
