Bug#1021835: libwebrtc-audio-processing-dev: missing dependencies

[Thomas Uhle]

Package: libwebrtc-audio-processing-dev
Version: 1.0-0.2
Severity: normal
Tags: patch, fixed-upstream
Followup-For: Bug #934811
X-Debbugs-Cc: Jonas Smedegaard <dr at jones.dk>

Dear maintainers,

some of the header files from version 1.0 of webrtc-audio-processing 
directly include header files from Abseil.  Thus, the binary package 
libwebrtc-audio-processing-dev should also depend on libabsl-dev.

Another issue is that the generated pkg-config data files 
webrtc-audio-coding-1.pc and webrtc-audio-processing-1.pc yet do not 
include the dependencies on the needed Abseil libraries because the 
current Meson build script still figures out these dependencies via 
CMake instead of using pkg-config.
This has already been fixed upstream as well as the missing dependency 
for using absl::optional<>.  You could pick up the following commits:

* Use pkg-config for abseil-cpp detection if available
   https://gitlab.freedesktop.org/pulseaudio/webrtc-audio-processing/-/commit/8bf9efad15bdb8438eb858d3f8ed4a8ea2b21ff0

* Add missing absl library for bad_optional_access
   https://gitlab.freedesktop.org/pulseaudio/webrtc-audio-processing/-/commit/0cc2ebeda2faf60f3367bd5e88e1247455dfcfee

If you don't like to pick up partial commits, you'll probably also need 
to pick up this commit from upstream:

* build: Add library-based absl detection as a fallback
   https://gitlab.freedesktop.org/pulseaudio/webrtc-audio-processing/-/commit/e74894baebe0bba7a7fe37ae0a46a2e9b1b2e021


Thank you in advance!

Best regads,

Thomas Uhle
