Compile as Win32

I used clFFT in my code. When I compiled it as x64, it works fine. But when I tried to compile it as Win32, I have "unresolved external symbol" errors. I am using version 2.12.2. My operation system is Windows10 x64. My Visual Studio is 2019 x64. Does the version 2.12.2 support Win32? If it doesn't, is there a version that supports Win32? Thanks.
