I’ve been trying to compile the newest version of aseprite (1.2 I believe), and have figured out how to complete the whole process, the only problem I am facing is when I follow the instructions I call 'cmake ’ and it does everything correctly or at least it looks like it does, but when I try to run the last command ‘ninja aseprite’ I get the error in the title “ninja: error: loading ‘build.ninja’: No such file or directory”, I have started from scratch around 4 times and I get the same error everytime, does anyone know why? or how i can fix this?. my operating system is Mojave 10.14.6
thanks 
In the MacOS dependencies section it’s written version 10.15 is required and you said yours is 10.14… Maybe that’s the problem.
you’re completely right, I overlooked that part and only saw the SDK which I do have up to date, I will try that. Thanks
turns out mojave 10.15.3 does not exist, I think they maybe meant Catalina ?
Yeah 10.15 is called Catalina. Mojave is 10.14
