WebKitRequirements: https://github.com/WebKitForWindows/WebKitRequirements/releases/tag/v2020.05.08

Issue description:
We tried to build WebKit using VS2019 on Windows Server 2016. WebKit failed to build due to link error on windows with MSVC. It can be reproduced on master branch latest commit 577b3e6. Could you please help take a look at this? Thanks in advance!

Repro steps:
1. git clone https://github.com/WebKit/webkit F:\gitP\WebKit\webkit
2. open a VS 2019 x86 command prompt as admin and browse to F:\gitP\WebKit\webkit
3. extra WebKitAuxiliaryLibrary to F:\gitP\WebKit\webkit\WebKitLibraries\win
4. extra WebKitSupportLibrary to F:\gitP\WebKit\webkit\WebKitLibraries\win
5. mkdir build_x86 && pushd build_x86
6. cmake -G "Visual Studio 16 2019" -A Win32 -DCMAKE_SYSTEM_VERSION=10.0.18362.0 -DCMAKE_BUILD_TYPE=Release -DRUBY_LIBRARY=C:\tools\ruby26\lib -DPORT="AppleWin" ..
7. msbuild /p:Platform=Win32 /p:Configuration=Release WebKit.sln /t:Rebuild

Actual result:
F:\gitP\WebKit\webkit\linkrepro>link @link.rsp

Those functions should be in CoreText.lib of the latest WebKitSupportLibrary.zip.
Are you using old WebKitSupportLibrary.zip?

[Myles C. Maxfield]

You can get the latest version of the WebKit support library here: https://developer.apple.com/opensource/internet/webkit_sptlib_agree.html

[QuellaZhang]

Thanks, I tried latest WebKitAuxiliaryLibrary(https://webkit.org/webkit-on-windows/#build-webkit) and WebKitSupportLibrary(https://developer.apple.com/opensource/internet/webkit_sptlib_agree.html), same error.

[Fujii Hironori]

Umm, weird.
AFAICT, the latest AppleWin can compile on my PC.
> perl .\Tools\Scripts\build-webkit --release --no-ninja

You should check your CoreText.lib really has CTFontTransformGlyphs.
Here is my result.

> PS C:\home\webkit\gc> dumpbin.exe /exports .\WebKitLibraries\win\lib64\CoreText.lib | findstr CTFontTransformGlyphs
>                   CTFontTransformGlyphs

[Fujii Hironori]

Ah, you are building 32bit version of AppleWin. lib32/CoreText.lib is not updated. Try 64bit AppleWin. I'd like to recommend you to use build-webkit script.

[QuellaZhang]

Ha, thanks, 64bit AppleWin compiles, I will add x64 build arch. BTW, do you have a plan to update lib32? :)

And thanks for your suggestions, I will try to use build-webkit script

Here's the way to get a 32-bit CoreText.lib
1. Download 32-bit Apple Application Support(comes from iTunes or QuickTime)
2. Find CoreText.dll from the install directory of AAS
3. run these commands to get CoreText.lib from dll
dumpbin /exports CoreText.dll > CoreText.def
lib /def:CoreText.def /machine:i386 /out:CoreText.lib
4. replace CoreText.lib in WebKitLibraries\win\lib32
5. build your project
I've tried build 32-bit AppleWin by VS2017, It works!

[Fujii Hironori]

AppleWin port was removed.
