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.
