How should I compile 32-bit programs that can run on win7?

[Guozht]

I have successfully compiled the 64 bit program in the VS2019 - WIN10 compilation environment. The program can run normally in win10, but an error is reported in WIN7 and the program input point SWDeviceCreate is not found in CFGMGR32.dll.

Then I compile 32-bit programs

Compilation environment WIN10

VS2019

llvm-win64

Then an error is reported: OneCoreUAP.lib cannot be found.

How can I successfully compile 32-bit programs that can run on WIN7?

Is there an article that guides the compilation of 32-bit programs?
