[Debian-med-packaging] Bug#1146800: timg: ftbfs with openslide 4.0.1 in experimental

[Tobias Frost]

PS: 
https://github.com/pkgconf/pkgconf/issues/300
https://github.com/pkgconf/pkgconf/issues/352

might be what's going on.
Upstream pkgconfig updated their docs in
https://github.com/pkgconf/pkgconf/pull/353 

so I guess, everything whats in required.private nees a dependency in
openslide. 
The question is if openslide should list those in required.private,
not sure. they might be needed for static linking, but does openslide
ship a static library?
