1.克隆代碼

git clone https://github.com/google/skia

2.下載依賴，需要額外的網絡 

python2 tools/git-sync-deps

3.如果vs安裝的目錄不在C盤，修改一下gn/find_msvs.py文件，指定vs目錄

default_dir = r'D:\Program Files (x86)\Microsoft Visual Studio',

4.指定windowssdk安裝目錄，需要額外下載windows sdk，自帶的不能用，找不到stddef.h等文件

指定sdk路徑 修改gn/BUILDCONFIG.gn

win_sdk = "D:/Windows Kits/10"

5.把上邊的編譯指令拷貝到build.bat中

build.bat
