https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      The portable DjVu viewer (Qt5) and browser (nsdejavu) plugin.
+
+      Djview highlights:
+        - entirely based on the public DjVulibre api.
+        - entirely written in portable Qt5.
+        - works natively under Unix/X11, MS Windows, and macOS X.
+        - continuous scrolling of pages
+        - side-by-side display of pages
+        - ability to specify a url to the djview command
+        - all plugin and cgi options available from the command line
+        - all silly annotations implemented
+        - display thumbnails as a grid
+        - display outlines
+        - page names supported (see djvused command set-page-title)
+        - metadata dialog (see djvused command set-meta)
+        - implemented as reusable Qt widgets
+
+      nsdejavu: browser plugin for DjVu. It internally uses djview.
+      Has CGI-style arguments to configure the view of document (see man).
