Bug#947065: linphone: Please drop sgmltools-lite build-dependency, unused

[Dimitri John Ledkov]

Package: linphone
Version: 3.12.0-3
Severity: serious

Dear Maintainer,

Linphone ships a 10 year old .lyx manual, which is prebuilt to .sgml
manual, which is compiled by Makefile.am/configure, which has not been
ported to CMake, and CMake buildsystem has been used forever.

sgmltools-lite is going away. If you need to compile sgml manual in
the future, simply use docbook-utils.

Meanwhile please drop the build-dependency on sgmltools-lite.

Regards,

Dimitri.
