windows cross-compile failing for out-of-date SDK

Here is the error I get:

configure:4923: checking for w32api version >= 3.14
configure:4937: i686-w64-mingw32-gcc -c   conftest.c 1>&5
configure:4953: checking for windres version >= 2.14.90
configure:4977: checking for i686-w64-mingw32-widl
configure:5030: checking for highest Windows version supported by this SDK
configure:5073: checking for Windows SDK being recent enough
configure: error: You are targeting Windows version 0x06030000, but your SDK only supports up to version 0x06020000. Install and use an updated SDK, or target a lower version using --with-windows-version. Alternatively, try running the Windows SDK Configuration Tool and selecting a newer SDK. See https://developer.mozilla.org/En/Windows_SDK_versions for more details on fixing this.
*** Fix above errors and then restart with\
               "make -f client.mk build"
make: *** [configure] Error 1

So we need to update some library, I guess?

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
