gdal is not the correct package to fix the armadillo dependencies,
libgdal20 gets its armadillo dependencies from ${shlibs:Depends} which
is populated with dependency information for libraries it links to.
armadillo doesn't use symbols files for its libraries to set correct
versioned dependencies, nor does it use `dh_makeshlibs -V` for versioned
library dependencies.
The armadillo package will need to adopt either symbols files or use
`dh_makeshlibs -V` to have packages that link to libarmadillo use a
versioned dependency.
Since maintaining symbols files for C++ libraries is a pain, I suggest
to use `dh_makeshlibs -V` for armadillo, or use the pkgkde-symbolshelper
for C++ symbols files.
Kind Regards,
Bas
