   4 Subject: [PATCH 7/9] Symlink the shared library to pwd.
   5
   6 DESTDIR is used, for instance, by distros to facilitate installing
   7 to a temp path for testing / package-building.
   8
   9 In general nDPI supports DESTDIR (yay!), but using an absolute path
  10 for the target of the library link has two problems:
  11
  12 1) If DESTDIR is set to /some/tmp/path, we end up with a link that
  13 points to /some/tmp/path/usr/lib/libndpi-x.y.z, which is definitely
  14 not what is intended - once the package is installed, the link is
  15 broken.
  16
  17 2) Absolute links are problematic for distributions; pointing to
  18 /usr/lib/libndpi-x.y.z during package build-and-test would point to
  19 either a nonexistent file, or an old and possibly wrong one.
  20
  21 Both of these are avoided if we just link to the target with no path
  22 at all.
