首先來看WTF這個project，這個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"
這些腳本首先利用vs自帶的一些內置變量來設置環境變量，然後調用"$(ProjectDir)$(ProjectName)PreBuild.cmd"這個腳本，展開後的路徑是D:/tools/cygwin/home/xufan/WebKit/Source/JavaScriptCore/JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCorePreBuild.cmd。從上面的28-31行可以看出，cmd /c的主要作用是爲了清除errorlevel。JavaScriptCorePreBuild.cmd這個腳本的內容如下：
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首先檢查前面的編譯有沒有問題，如果沒有問題，就會調用D:/tools/cygwin/home/xufan/WebKit/WebKitLibraries/win/tools/scripts/auto-version.sh這個perl腳本，內容如下：

auto-version.sh這個腳本主要是根據D:/tools/cygwin/home/xufan/WebKit/WebKitLibraries/win/tools/scripts/VERSION，D:/tools/cygwin/home/xufan/WebKit/WebKitLibraries/win/tools/scripts/COPYRIGHT-END-YEAR以及當前時間等生成D:/tools/cygwin/home/xufan/WebKit/WebKitBuild/Debug_Cairo_CFLite/obj/JavaScriptCore/include/autoversion.h這個描述版本信息的頭文件，這個頭文件在生成後的格式如下：
1: #define __VERSION_TEXT__ "533+ - Mon Jan 31 12:26:06 2011 - r77102"
2: #define __BUILD_NUMBER__ "533+ - Mon Jan 31 12:26:06 2011 - r77102"

這些信息會體現在javascriptcore.dll這個文件的版本信息裏面，如下圖：
執行完prebuild腳本後，就要開始編譯了。wtf這個project有一些屬性是從別的vsprops文件集成來的，如下圖：
這些vsprops文件包含：
../../../../WebKitLibraries/win/tools/vsprops/FeatureDefinesCairo.vsprops

這個文件包含了定義了公用的宏，PreBuildEvent，PostBuildEvent等，例如上面講到的PreBuildEvent就是在這裏定義的。

WTFCommon.vsprops這個文件定義了wtf這個工程依賴的頭文件目錄和庫等。
需要注意的是，FeatureDefinesCairo.vsprops,common.vsprops,release.vsprops,WinCairo.vsprops是大部分webkit工程都會繼承的，因此修改後會一些所有繼承這幾個文件的工程。例如如果你想將webkit編譯依賴的crt由Multi-threaded DLL(/MD)改爲Multi-threaded (/MT)，只需要修改release.vsprops這個文件的RuntimeLibrary這個屬性即可。
WTF這個工程的編譯過程就和普遍的vc工程一樣了，這裏就不介紹了。
WTF這個工程的PreLink Event和PostBuild Event主要是調用WTFPreLink.cmd和WTFPostBuild.cmd，這兩個bat都比較簡單，就不介紹了。
