Build stops at last command

I’ve been following this tutorial and I got to the last stage of the building process but I keep getting this error:

ninja: error: ‘C:/deps/skia/out/Release-x64/skia.lib’, needed by ‘bin/aseprite.exe’, missing and no known rule to make it

Does anyone have any idea how to fix this?
(I’ve tried redownloading Skia and Ninja multiple times each but nothing is working so far)
(also I’m compiling on windows)
