[Debian-med-packaging] Bug#635300: libinsighttoolkit3-dev: do not export library dependencies with full paths

[Michael Schutte]

Package: libinsighttoolkit3-dev
Version: 3.20.0-10
Severity: normal

To support transitive linking for its reverse dependencies, the package
ships /usr/lib/InsightToolkit/ITKLibraryDepends.cmake, containing not
only the names but also the absolute paths to the shared objects at the
time of building.

This is obviously a bad idea because it will make every ITK-based
package FTBFS whenever a library path changes (which currently happens
frequently due to multiarch).  Rather than rebuilding insighttoolkit
each and every time, it is preferable to completely replace this brittle
solution.

I don’t know how difficult this will be, and whether the rdeps will have
to be fixed as well.  Possible solutions (off the top of my head) could
include getting rid of the paths altogether, or replacing them with
variables whose values have to be determined by the rdeps at their build
time.

Cheers,
