CMake Errors... M1 Mac mini

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

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:


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.
