NanoGui wouldn't generate project with CMake

Anybody have any lucky with NanoGui, I see there are some videos on youtube of programmers using NanoGui for OpenGL projects.

I downloaded the full repository from, but could not get Cmake to generate a project. It would not successfully complete the Configure mode. Any ideas? I love the look of this GUI, and would love to learn how to implement it, and produce a youtube tutorial to show others, but I would have to be able to use it first.

On a related note, any other out of the box GUIs that you find easy to use? Aside from making one myself, which is what I am now considering, since this didn’t work for me.

Thanks guys,
