Issues with CMake and Compiling Aseprite

Hey there! I am trying to compile aseprite on my D: drive
The following happens when I try to do so:

Any help will be appreciated

This happens when I use
git submodule update --init --recursive

looks like you download the repository directly from GitHub’s Code → Download ZIP, which doesn’t include any of the submodules, and is a snapshot rather than a real git repository folder.
You shold use git clone --recursive to clone the whole repository recursively, then follow the instruction in the docs to download the prebuilt skia lib, then use cmake to generate the makefile, with your downloaded skia folder specified, and build the whole thing.
