Liquidsoap new version build failure

[Kyle Robbertze <paddatrapper@debian.org>]

Hi,

Liquidsoap has finally moved to Dune as its build system. However, I am 
getting the following error when trying to build. Does anyone know how 
to fix it?

   dh_update_autotools_config -O--buildsystem=ocaml_dune
   dh_autoreconf -O--buildsystem=ocaml_dune
   dh_ocamlinit -O--buildsystem=ocaml_dune
   dh_auto_configure -O--buildsystem=ocaml_dune
   dh_auto_build -O--buildsystem=ocaml_dune
        dune build -j 5 -p 
liquidsoap,liquidsoap-core,liquidsoap-lang,liquidsoap-js,liquidsoap-libs,liquidsoap-libs-extra,liquidsoap-mode,tls-liquidsoap,sdl-liquidsoap
File "src/runtime/dune", line 4, characters 7-17:
4 |   (pps ppx_string))
           ^^^^^^^^^^ 

Error: Library "ppx_string" not found.
-> required by library "liquidsoap_runtime" in _build/default/src/runtime
