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

+Subject: [PATCH 8/9] Use a more standard path for pkg-config files.
+
+The Linuxes I've checked all seem to use /usr/{,local/}lib*/pkgconfig,
+not /usr/libdata/.  I think FreeBSD does use /usr/libdata/ but also
+supports /usr/lib*/pkgconfig, although I have not tested this change
+on a FreeBSD system.

+Subject: [PATCH 9/9] Correct the include file path in -I CFLAGS argument.
+
+src/lib/Makefile.in install headers into ${prefix}/include/ndpi,
+but the shipped libndpi.pc.in specifies a different path.  Therefore
+anything trying to build using $(pkg-config --cflags libndpi) will
+fail to find the nDPI headers.
+
+This patch simply makes libndpi.pc.in agree with src/lib/Makefile.in.
