Add platform dependent path into pro file problem

[alizadeh91]

Hi,
I've created simple project and i want to add a library to my project and i want to add its path base on my platform so i did this in my pro file:

win32
{
    INCLUDEPATH += C:\Qwt-6.0.2\include
    LIBS += -LC:\Qwt-6.0.2\lib -lqwt
 
    CONFIG += qwt
}

win32
{
    INCLUDEPATH += C:\Qwt-6.0.2\include
    LIBS += -LC:\Qwt-6.0.2\lib -lqwt

    CONFIG += qwt
}

To copy to clipboard, switch view to plain text mode 

but i get " error: Parse Error ('win32')" . When i remove win32 it works fine. any suggestion?
