Issue with final compiling command

Hi, so I’ve been trying to compile aseprite and so far everything has been working until the final command when I type Ninja Aseprite. A ton of issues come up all saying its missing something and this is one of them. Does anyone know what to do?: third_party/CMakeFiles/lualib.dir/lua/linit.c.obj

Hi @Lilyisnotaloser! First of all you need to install the necessary dependencies to be able to compile Aseprite. Here are the instructions depending on your operating system: https://github.com/aseprite/skia#building-skia.
