How to link SetupAPI.lib both for 32-bit and 64-bit platform?

Hi, Good Day!

I'm having problem regarding on linking of setupAPI.lib in both 64-bit and 32-bit platform.
I tried the code below, in the .pro file to link the setupAPI.lib and it works in 32bit.

win32: LIBS += 'C:/Program Files (x86)/Microsoft SDKs/Windows/v6.1/lib/SetupAPI.lib'

But, how if I work in 64-bit platform? How my project be compatible both 64bit and 32bit platform?
Any code suggestion to solve the problem?

Thanks in advance..
