build qwt qtlibinfix

[Stas1]

I have a similar problem.

In my platform qmake.conf there is QT_LIBINFIX set to 4.
Building Qwt produced qwt.dll.
But when I try to build my project it tries to link to qwt4.

If I understand it correctly, the build system should have produced 'qwt4.dll', not 'qwt.dll'.

I found that qwtAddLibrary function adds infix to the name, while the qwtLibraryTarget does not. How can this possibly work? Is this not an inconsistency?
It is similar way in both customised qwt's qwtfunctions.pri and standard qt_functions.prf.

I am not sure if this is a misconfiguration in Qt or Qwt so not sure where to look for a fix.

I tried to comment out QT_LIBINFIX definition in qmake.conf but it affects all libraries and tries to link to 'QtCore' instead of 'QtCore4' for example.
Meanwhile I modified qwtAddLibrary in qwt's qwtfunctions.pri to not to take infix into account. I realise this is not correct but at least I can now carry on working on a project.

Any help or suggestion will be very much appreciated.

I use Qt 4.8.5 and Qwt 6.1.0 with mingw-w64 cross compiler.
