Tried to follow your instructions as written, but conflicts arose according to dnf:

Then when I moved on to trying to apply cmake ../ I found that the -devel versions weren't recognized by CMake, or, at least, weren't enough: I needed to get the "baseline" packages:

CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:619 (message):
  The following required packages were not found:

   - libsixel

Call Stack (most recent call first):

And finally

CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:619 (message):
  The following required packages were not found:

   - libavutil

Call Stack (most recent call first):
  /usr/share/cmake/Modules/FindPkgConfig.cmake:841 (_pkg_check_modules_internal)
  CMakeLists.txt:51 (pkg_check_modules)

Up until libavutil I managed to sort it out by searching dnf for the libraries and installing all variants. I ended up asking dnf to install

libsixel.x86_64 libsixel-devel.x86_64 libsixel-utils.x86_64
turbojpeg.x86_64 turbojpeg-devel.x86_64 
libexif.x86_64 libexif-devel.x86_64

Resulting in the installations of

(Yes, somehow libexif-devel got installed but not libexif - but if it was already there, why did I get an error from CMake complaining that it couldn't find it?

So far so good, though, but then I reached an impasse:

With libavutil, which was the origin of most of the conflicts in the original attempt at installing the resources (see above), I found myself hitting a wall:

libavutil-free-devel and the preexisting ffmpeg-libs are in conflict.

I tried to use CMake with the flags for the video decoding off so that it wouldn't try to use these dependencies, but I falied:

Any recommendations on how to proceed?

I don't have any recent Fedora experience, so I can't really help much.
Maybe you find someone who maintains the fedora timg package that can provide insight ?

Try installing ffmpeg-devel instead of libavutil-free-devel.

Media codecs in Fedora are a bit messy, since the Fedora repositories have a few limitations because of legal issues. This gets more annoying once you add RPMFusion and install ffmpeg.

I've just submitted timg for F40, so it should be available for F40 in ~7 days if nothing goes wrong; you won't have to compile it manually anymore.
