True, I guess. I was assuming it required OpenCV3 and wouldn't work at
all with V2 so I ran cmake with

   -DENABLE_OPENCV3=OFF

thinking it would not compile any OpenCV in. ldd confirms it's compiled
against OpenCV2. On a quick test, face recognition doesn't seem to do
anything, but I've never used it before, anyway. No issue for me.

I did, apparently though I read accidentally only the one that came with V4
(while working on compiling V4 and V5) and missed QT_PLUGIN_PATH and
XDG_DATA_DIRS variables required for V5.  
V5 beta starts now, thanks!

I would not either, if digikam was available via the official Debian
repo. I did it already for a while back in 2013, when no up-to-date
digikam V3 was available. I just hope V5 will make it into Debian
sometime.

I prefer to keep my system somewhat clean, and have anything not coming
via a Debian or deb-multimedia repo in /usr/local/.

Yes.

liblqr-1-0-dev is installed via the official stretch repo.
lqr.h is in /usr/include/lqr-1

   # pkg-config --cflags lqr-1
   -I/usr/include/lqr-1 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include

Compiler call above doesn't have -I/usr/include/lqr-1 and so c++ says:

   fatal error: lqr.h: No such file or directory

I am simply running bootstrap.linux of digikam-4.14.0 and cmake doesn't
get the CFLAGS right. Either a digikam or a Debian package issue, but I
don't know cmake well enough to find out where something is missing, and
possibly fix it.

Thanks for your time and answers, Gilles!
