You are on the right track!

We can safely ignore that warning.

The nsis script is made so that the installation to root isn't necessary. For that you need to change the DESTDIR:

make install DESTDIR=/tmp/some-tmp-dir
makensis data/virt-viewer.nsis -DDESTDIR=/tmp/some-tmp-dir


I have some pending patches to add a Makefile target simplifying this process.

Right, I also have a pending patch updating the needed files, I´ll resubmit. Thanks for the reminder

That's most likely because virt-viewer got compiled without spice support.
Make sure you have mingw-spice-gtk installed, and run mingw64-configure --with-spice-gtk

I am not sure this one has been made public yet. The problem is that usb redirection support on windows requires building with MSVC some USB components atm, and can't be made available easily on upstream & Fedora. Help would be appreciated to fully cross-compile the USB support!
