Yes, you need to pass -lvirt when linking. The library is installed 
wherever you told it to install. If you ran plain meson with no extra 
arguments, then 'meson install' installs library under /usr/local/lib/ 
or /usr/local/lib64/. So you will need to pass -L/usr/local/lib or 
-L/usr/local/lib64 too to the linker.

But there is this switch -Dsystem=true which tells meson to install into 
system directories:

   meson -Dsystem=true build
   meson install -C build

with this you will not need to pass any extra -L arguments to the linker.
