首先来看WTF这个project，这个project的Pre-build event如下：
1: REM Do not edit from the Visual Studio IDE! Customize via a $(ProjectName)PreBuild.cmd file.
2: if not exist "$(ProjectDir)$(ProjectName)PreBuild.cmd" exit /b
3:
4: set CONFIGURATIONBUILDDIR=$(ConfigurationBuildDir)
5: set CONFIGURATIONNAME=$(ConfigurationName)
6: set INPUTDIR=$(InputDir)
7: set INPUTFILENAME=$(InputFileName)
8: set INPUTPATH=$(InputPath)
9: set INTDIR=$(IntDir)
10: set LIBRARYCONFIGSUFFIX=$(LibraryConfigSuffix)
11: set OUTDIR=$(OutDir)
12: set PLATFORMNAME=$(PlatformName)
13: set PROJECTDIR=$(ProjectDir)
14: set PROJECTFILENAME=$(ProjectFileName)
15: set PROJECTNAME=$(ProjectName)
16: set PROJECTPATH=$(ProjectPath)
17: set SOLUTIONDIR=$(SolutionDir)
18: set SOLUTIONFILENAME=$(SolutionFileName)
19: set SOLUTIONNAME=$(SolutionName)
20: set SOLUTIONPATH=$(SolutionPath)
21: set TARGETDIR=$(TargetDir)
22: set TARGETEXT=$(TargetExt)
23: set TARGETFILENAME=$(TargetFileName)
24: set TARGETPATH=$(TargetPath)
25: set WEBKITCONFIGSUFFIX=$(WebKitConfigSuffix)
26: set WEBKITDLLCONFIGSUFFIX=$(WebKitDLLConfigSuffix)
27:
28: REM If any of the above variables didn't exist previously and
29: REM were set to an empty string, set will set the errorlevel to 1,
30: REM which will cause the project-specific script to think the build
31: REM has failed. This cmd /c call will clear the errorlevel.
32: cmd /c
33:
34: "$(ProjectDir)$(ProjectName)PreBuild.cmd"
这些脚本首先利用vs自带的一些内置变量来设置环境变量，然后调用"$(ProjectDir)$(ProjectName)PreBuild.cmd"这个脚本，展开后的路径是D:/tools/cygwin/home/xufan/WebKit/Source/JavaScriptCore/JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCorePreBuild.cmd。从上面的28-31行可以看出，cmd /c的主要作用是为了清除errorlevel。JavaScriptCorePreBuild.cmd这个脚本的内容如下：
1: %SystemDrive%/cygwin/bin/which.exe bash
2: if errorlevel 1 set PATH=%SystemDrive%/cygwin/bin;%PATH%
3: cmd /c
4: if exist "%CONFIGURATIONBUILDDIR%/buildfailed" grep XX%PROJECTNAME%XX "%CONFIGURATIONBUILDDIR%/buildfailed"
5: if errorlevel 1 exit 1
6: echo XX%PROJECTNAME%XX > "%CONFIGURATIONBUILDDIR%/buildfailed"
7:
8: bash "%WEBKITLIBRARIESDIR%/tools/scripts/auto-version.sh" "%INTDIR%"
JavaScriptCorePreBuild.cmd首先检查前面的编译有没有问题，如果没有问题，就会调用D:/tools/cygwin/home/xufan/WebKit/WebKitLibraries/win/tools/scripts/auto-version.sh这个perl脚本，内容如下：

这些信息会体现在javascriptcore.dll这个文件的版本信息里面，如下图：
执行完prebuild脚本后，就要开始编译了。wtf这个project有一些属性是从别的vsprops文件集成来的，如下图：
这些vsprops文件包含：

../../../../WebKitLibraries/win/tools/vsprops/common.vsprops ../../../../WebKitLibraries/win/tools/vsprops/release.vsprops ../../../../WebKitLibraries/win/tools/vsprops/WinCairo.vsprops ./WTFCommon.vsprops首先看D:/tools/cygwin/home/xufan/WebKit/WebKitLibraries/win/tools/vsprops/FeatureDefinesCairo.vsprops这个文件：

这个文件包含了定义了公用的宏，PreBuildEvent，PostBuildEvent等，例如上面讲到的PreBuildEvent就是在这里定义的。

release.vsprops这个文件主要定义编译的一些选项，例如使用的crt版本，优化选项等。

WinCairo.vsprops定义了cairo这个版本的wenkit编译需要依赖的头文件目录和库文件。

WTFCommon.vsprops这个文件定义了wtf这个工程依赖的头文件目录和库等。
需要注意的是，FeatureDefinesCairo.vsprops,common.vsprops,release.vsprops,WinCairo.vsprops是大部分webkit工程都会继承的，因此修改后会一些所有继承这几个文件的工程。例如如果你想将webkit编译依赖的crt由Multi-threaded DLL(/MD)改为Multi-threaded (/MT)，只需要修改release.vsprops这个文件的RuntimeLibrary这个属性即可。
WTF这个工程的编译过程就和普遍的vc工程一样了，这里就不介绍了。
WTF这个工程的PreLink Event和PostBuild Event主要是调用WTFPreLink.cmd和WTFPostBuild.cmd，这两个bat都比较简单，就不介绍了。
