qtcreator specific x64 define

[Le_B]

hello all,

i have a project i want to compile in x86 and x64 with qtcreator
i want to specify a DLLDESTDIR for each configuration.
i have already :
win32:CONFIG(debug, debug|release)LLDESTDIR = <my_path>
is there a win64: or something that can help me ?

thanks

i found a way :

contains(DEFINES, WIN64){
//x64 propertoes
}

!contains(DEFINES, WIN64){
//x86 properties
}

maybe there s a better way though...
