检测 ICU 库在 VS2017 中失败

>我正在使用VS2017构建工具从源代码构建Qt 5.11.1。 我设置的环境如下：

set QTDIR=%CD%
set PATH=%PATH%;%QTDIR%qtbasebin;C:Oracle11client11.2.0bin;C:Python27;C:ruby_2.0.0bin;C:Python27Scripts;C:Perl64sitebin;C:Perl64bin;C:GnuWin32bin;C:icubin64
call "C:Program Files (x86)Microsoft Visual Studio2017ProfessionalVCAuxiliaryBuildvcvars64.bat"
set INCLUDE=%INCLUDE%;C:appclientxproduct12.2.0client_1ociinclude;C:Python27include;C:ruby_2.0.0include;"C:mysql-5.5include;C:icuinclude";"C:Program Files (x86)Windows Kits10Include"
set LIB=%LIB%;C:appclientxproduct12.2.0client_1ocilibmsvc;C:Python27Lib;C:ruby_2.0.0lib;"C:mysql-5.5lib";C:iculib64;"C:Program Files (x86)Windows Kits10Lib"

然后调用configure脚本：

configure -prefix %QTDIR%_STAGE -platform win32-msvc -commercial -confirm-license -release -shared -qt-libjpeg -qt-libpng -no-cups -no-mtdev -nomake examples -icu -plugin-sql-mysql -plugin-sql-odbc -plugin-sql-sqlite -opengl dynamic -skip qtconnectivity -skip webengine -D _IGNORE_FINAL

该脚本执行一些工作，并且在检查配置时失败 - 找不到icu：

ERROR: Feature 'icu' was enabled, but the pre-condition 'libs.icu' failed.  
Check config.log for details.

以下是config.log的相关部分：

我试图从config.testsicu构建独立的main.cpp

cl main.cpp /EHsc

并得到相同的链接器错误。然后我添加了库路径和库，构建成功：

cl main.cpp /EHsc /link /LIBPATH:C:iculib64 icudt.lib icuin.lib icuio.lib icule.lib iculx.lib icutu.lib icuuc.lib

但是当我添加库来配置脚本时，遇到了相同的链接器错误。

知道我做错了什么或错过了什么吗？
