I’m on windows 10, and I followed every instruction from [How to compile Aseprite 2020 || Get Aseprite for FREE! - YouTube](https://www.youtube.com/watch?v=WKeNJh_gIJU), and that was the error message I got when I ran C:\aseprite\build\>ninja aseprite
Every forum thread I found with people having this problem either their was no answer or the answer was very unclear or for another operating system.
