Run on a Windows 64-bit operating system either as a native application or under WOW64

Question

I am using Visual Studio 2013 Professional, and need to compile my application in a way that it works with existing libraries on my system that are only 32 bit.
I read this someplace ....   "When you compile an application, you can specify that it should run on a Windows 64-bit operating system either as a native application or under WOW64 (Windows 32-bit on Windows 64-bit). WOW64 is a compatibility
environment that enables a 32-bit application to run on a 64-bit system. WOW64 is included in all 64-bit versions of the Windows operating system."
Can anyone tell me HOW I "specify that it should run on a Windows 64-bit operating system either as a native application or under WOW64 (Windows 32-bit on Windows 64-bit)."  ?
