Detection of icu libs fails with VS2017 - c++

Question

I'm building Qt 5.11.1 from sources with VS2017 build tools.
The environment I set is as follows:
set QTDIR=%CD%
set PATH=%PATH%;%QTDIR%\qtbase\bin;C:\Oracle11\client11.2.0\bin;C:\Python27\;C:\ruby_2.0.0\bin;C:\Python27\Scripts\;C:\Perl64\site\bin;C:\Perl64\bin;C:\GnuWin32\bin;C:\icu\bin64
call "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Auxiliary\Build\vcvars64.bat"
set INCLUDE=%INCLUDE%;C:\app\client\x\product\12.2.0\client_1\oci\include;C:\Python27\include;C:\ruby_2.0.0\include;"C:\mysql-5.5\include;C:\icu\include";"C:\Program Files (x86)\Windows Kits\10\Include"
set LIB=%LIB%;C:\app\client\x\product\12.2.0\client_1\oci\lib\msvc;C:\Python27\Lib;C:\ruby_2.0.0\lib;"C:\mysql-5.5\lib";C:\icu\lib64;"C:\Program Files (x86)\Windows Kits\10\Lib"
then call the configure script:
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
The script does some work, and when checking the configurations, it fails - cannot find icu:
ERROR: Feature 'icu' was enabled, but the pre-condition 'libs.icu' failed.
Check config.log for details.
Here's the relevant part from config.log:
loaded result for library config.qtbase_corelib.libraries.icu
Trying source 0 (type inline) of library icu ...
=> source failed condition 'config.win32 && !features.shared'.
Trying source 1 (type inline) of library icu ...

I tried to build the standalone main.cpp from config.tests\icu with
cl main.cpp /EHsc
and got the same linker error. Then I added the libs path and the libs and the build succeeded:
cl main.cpp /EHsc /link /LIBPATH:C:\icu\lib64 icudt.lib icuin.lib icuio.lib icule.lib iculx.lib icutu.lib icuuc.lib
But when I added the libs to configure script, got the same linker error.
Any idea what I'm doing wrong or missing?

Answer 1

try to move icu lib path to the first and re-configure seems solve the problem
