Bug#924300: libnglib-6.2.1804: ldconfig does not find netgen shared object files

[Sebastian Bachmann]

Package: libnglib-6.2.1804
Version: 6.2.1804+dfsg1-3
Severity: normal

Dear Maintainer,

I used netgen to build FreeCAD but without setting LD_LIBRARY_PATH, FreeCAD's
FEM workbench does not start up, as the required netgen libraries are not found
by ldconfig:

$ dpkg -L libnglib-6.2.1804:amd64
/.
/usr
/usr/lib
/usr/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu/netgen
/usr/lib/x86_64-linux-gnu/netgen/libcsg.so

# ldconfig -p | grep libcsg
# echo $?
1

It looks like the problem is, that netgen installs itself into the netgen
folder but does not provide symlinks to the parent folder or a ld.so.conf.

The problem can be worked around by starting FreeCAD with a LD_LIBRARY_PATH set
to the netgen folder.

regards
Sebastian
