Trying to build example on Mac

[calebjacksonhoward]

I'm trying to make the examples on a Mac, and I get the following errors. It has been more than a decade since I've worked in C++, and so I am a newb anew, in many regards. (I am also new to Mac - from a lifetime of UNIX->IRIX->Linux.). I understand the concepts well, but am out of practice, and the HW and SW has changed since I last worked with C++. Perhaps someone can give me a hint and save me some time. A quick googling isn't helping me:

Thanks

The sample is for Windows only. If you want to have the samples on Linux or MacOS, you'll need to add support for other windowing system/inputs. Another possibility is to use a 3rd party library like SDL for GLFW just like Dear Imgui.

Then I tried building on Windows, but couldn't get an env configured for make, nor cmake.

[CedricGuillemet]

There is a visual studio project : https://github.com/CedricGuillemet/ImGuizmo/blob/master/example/ImGuizmoSample.vcxproj

Perfect. Thanks. I don't generally have to deal with Windows. I am unused to the requirement of a specific proprietary IDE to build code. I appreciate the pointer.
