Package: openslide Version: 4.0.1+dfsg-1 Severity: serious After installing pkgconf and libopenslide-dev in a fresh sid container:
# pkg-config --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 Package 'gio-2.0', required by 'openslide', not found Package 'gobject-2.0', required by 'openslide', not found Package 'cairo', required by 'openslide', not found Package 'libxml-2.0', required by 'openslide', not found Package 'libtiff-4', required by 'openslide', not found Package 'libopenjp2', required by 'openslide', not found Package 'libjpeg', required by 'openslide', not found Package 'libpng', required by 'openslide', not found Package 'zlib', required by 'openslide', not found Package 'libzstd', required by 'openslide', not found pkg-config is the supported way to determine how to link with OpenSlide, and pkg-config requires the .pc files mentioned in openslide.pc's Requires.private to exist, so libopenslide-dev isn't useful without the -dev packages that provide these files. By policy 3.5, libopenslide-dev must therefore depend on those packages. A couple such dependencies were added in #1146800; see previous discussion there.
