How to use KIT name for loading library

[pou_cz]

Hello,
i'm using a few kits in QTcreator. But I need load right library for each kit.
I need something like this:
win32:INCLUDEPATH += "C:/mylibs/extra headers"
unix:INCLUDEPATH += "/home/user/extra headers"
But our kits is always unix, so i need decide by KIT name - it's possible?
KIT1:LIBS+= -L../staticLibrary/kit1 -lstaticLibrary
KIT2:LIBS+= -L../staticLibrary/kit2 -lstaticLibrary

Thanks
