[Debian-med-packaging] Bug#734375: Missing dependency on libglib2.0-dev

[Benjamin Gilbert]

Package: libopenslide-dev
Version: 3.3.3-1

openslide.pc contains the line:

Requires.private: glib-2.0 gthread-2.0

but libopenslide-dev does not depend on libglib2.0-dev.  As a result, 
after installing libopenslide-dev on a minimal system:

$ pkg-config --cflags --libs openslide
Package glib-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `glib-2.0.pc'
to the PKG_CONFIG_PATH environment variable
Package 'glib-2.0', required by 'openslide', not found
