Bug#833271: librtaudio-dev: rtaudio.pc depends on libpulse-simple

[IOhannes m zmölnig (Debian/GNU)]

Package: librtaudio-dev
Version: 4.1.2~ds0-3
Severity: important

Dear Maintainer,

the rtaudio.pc as shipped with librtaudio-dev declares a dependency on
libpulse-simple:

    $ cat /usr/lib/x86_64-linux-gnu/pkgconfig/rtaudio.pc | grep pulse
    Requires:  alsa libpulse-simple
    $

Unfortunately the librtaudio-dev package does declare a dependency on a package
providing libpulse-simple. basically the following is missing:
> Depends: libpulse-dev

This results in rendering the pkg-config file rather useless:

    $ pkg-config --cflags rtaudio
    Package libpulse-simple was not found in the pkg-config search path.
    Perhaps you should add the directory containing `libpulse-simple.pc'
    to the PKG_CONFIG_PATH environment variable
    Package 'libpulse-simple', required by 'rtaudio', not found
    $

This is in turn is rather important, as it prevents any package that relies on
rtaudio's pkg-config and does not have an explicit Build-Depends on libpulse-dev
(because it doesn't use libpulse-dev functionality itself) to FTBFS, due to the
changed search path for the header-files.

See [1] for a failed build.
