That's odd. I'm trying here in my local computer:
- First you download the dependencies, I don't have the mingw32-usbredir
  so I've installed it with `dnf install mingw32-usbredir`

At spice-gtk folder:
$ mingw32-configure --with-usbredir=yes
the summary in the end shows 'USB redirection support: yes'
$ make && sudo make install

Now you have mingw32 spice-gtk. You can check with
$ mingw32-pkg-config --modversion spice-client-gtk-3.0.pc

Did you installed the mingw ones?

mingw32-configure sets the environment variables that you need,
including PKG_CONFIG_PATH. So, if you have installed mingw32-gtk3 it
will be insalled in mingw path and when you cross-compile it will look
for packages there.

Christophe provided the spice-gtk rpm with usbredirection enable.
I hope this steps can help you,
