Cannot find how to link to crypt32.dll

Hello there Qt folks! I am trying to use the function CryptProtectData defined and wincrypt.h (see http://msdn.microsoft.com/en-us/library/windows/desktop/aa380261(v=vs.85).aspx) and I need to link against crypt32.dll. And… I don’t know how to do it. I’ve found crypt32.dll at C:\Windows\System32\ but that doesn’t really help me solve the problem. Initially, I asked a question @stackoverflow (http://stackoverflow.com/questions/15614239/undefined-reference-to-imp-cryptprotectdata28) about the error and was told to link against crypt32.dll I’ve programmed quite a bit at Linux where the things (seemed to be, at least) quite simpler, using the PKG_CONFIG and let it find the libraries. Any tips on how to link against crypt32 would be grateful :)
