M1 Mac mini
OSX 11.4 (Big Sur)
What I’ve done:
get clone code of Aseprite
_directory: Users/Me/aseprite_ have build folder in it
get Ninja
get Skia
_directroy: Users/Me/deps/skia_ …/Skia-macOS-Release-x64 have build folder and CMakeLists.txt in it, depot\_tools folder installed
get CMake
when I tried to code from Github
```auto
cd aseprite
mkdir build
cd build
cmake \
-DCMAKE_BUILD_TYPE=RelWithDebInfo \
-DCMAKE_OSX_ARCHITECTURES=x86_64 \
-DCMAKE_OSX_DEPLOYMENT_TARGET=10.9 \
-DCMAKE_OSX_SYSROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk \
-DLAF_BACKEND=skia \
-DSKIA_DIR=$HOME/deps/skia \
-DSKIA_LIBRARY_DIR=$HOME/deps/skia/out/Release-x64 \
-DSKIA_LIBRARY=$HOME/deps/skia/out/Release-x64/libskia.a \
-G Ninja \
..
```
result:
```auto
ninja aseprite
mkdir: build: File exists
CMake Deprecation Warning at CMakeLists.txt:16 (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.

Hey there. I know this is a super necro, but I was struggling with this and couldn’t find a solid answer anywhere, so I figured I would post it here.
I followed the installation structions. Namely getting both `cmake` and `ninja` installed via Homebrew. I had everything set up in the right place, but couldn’t get it to make something for ninja to compile.
My issue was that `/Applications/XCode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk` was not the actual location of my MacOS SDK.
It was located at `/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk` Once I changed that line of the command, it worked like a charm.
This was because I had the XCode developer command line tools installed, instead of simply XCode. If anyone else is having issues with this, I highly recommend checking out where your MacOSX.sdk is hiding at.
Also, you’re saying you’re running on the M1 Apple Silicon, you should set your `-DCMAKE_OSX_ARCHITECTURES` to `ARM64` instead of the usual x86\_64 architecture. Be doubly sure you’ve made the deps directory in your $HOME directory as well, then moved skia into there
