I noticed this bug report while looking at unrelated release-critical
bug #997252 in the same package.
This class of bug is generally considered to be release-critical,
although arguably it might not be RC for libqt5gstreamer-dev if the
functionality of libqt5gstreamer-dev is normally located via CMake and
only rarely via pkg-config (maintainers: please downgrade if the .pc
files are considered to be unimportant in this particular package).
The .pc files also depend on libraries from libglib2.0-dev and
libgstreamer1.0-dev; in practice those get pulled in by installing
libgstreamer-plugins-base1.0-dev, but for completeness it's probably best
to add them as Depends explicitly. I would suggest the attached patch.
Qt5GStreamerQuick-1.0.pc also depends on a library from
qtdeclarative5-dev, which the other pkg-config modules do not. Any
level of dependency relationship between Depends and Suggests could be
argued to be correct here, depending on whether use of
Qt5GStreamerQuick-1.0.pc is common, rare or somewhere in between.
In the attached patch I've gone for Recommends, but the package's
maintainers would know better what's appropriate here.
> Alternatively, perhaps the pc files need to be shuffled between packages?
I think they are in the correct package, it just needs more dependencies
as you said.

Subject: [PATCH] Add missing dependencies on GLib/GStreamer -dev packages
Without these, the pkg-config metadata is not usable.
qtdeclarative5-dev is only needed for Qt5GStreamerQuick-1.0.pc,
so is set as a Recommends here.
Closes: #906882
