I'm not too sure what I'm doing wrong while compiling aseprite

I can’t really afford aseprite right now which is why I’ve been trying to compile aseprite as an alternative until I can eventually just buy it on steam. I’ve been trying to compile it all night and I have no idea what the issue is. I’m not very knowledgeable on programming at all but I’m pretty sure I’ve been following the instructions if anyone can help please let me know.

CMake Deprecation Warning at CMakeLists.txt:17 (cmake_policy):
The OLD behavior for policy CMP0046 will be removed from a future version
of CMake.

The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.
