Title:
  FTBFS: undefined references - affects zesty/all arches (orthanc-
  dicomweb 0.3+dfsg-1)

Status in orthanc-dicomweb package in Ubuntu:
  Confirmed
Status in orthanc-dicomweb package in Debian:
  New

Bug description:
  orthanc-dicomweb 0.3+dfsg-1 has been recently imported from Debian,
  unfortunately it FTBFS on all arches on zesty [1].

  The failure is triggered when linking CXX shared library
  libOrthancDicomWeb.so and causes quite a few "undefined reference" in
  various objects (Dicom.cpp.o, ...)

  The root cause is the out-of-order argument for the gdcm library. This
  bug was introduced by the debian/patches/cmake (packaged since 1.1)
  where cmake's target_link_libraries for gdcm libraries was replaced by
  a manual reference in LINK_FLAGS. The issue is that libraries should
  never be added to LINK_FLAGS (which behaves as LD_FLAGS in make) as
  they end up being declared before the objects that need them, instead
  the correct way is to rely on cmake's commands for that (there is no
  other equivalent to make's LD_LIBS).
