From the error message you need libgegl-dev installed, something like this
https://i.imgur.com/6994pta.jpg and possibly other dev files as well. I would start off with a
export LDFLAGS="$LDFLAGS -lm" (that is lower case LM) before
makeThe code for the plugin(s) has not changed since about 2012, I just can not see it being updated for Gimp 2.10 The question has been asked before.
However it does compile, with plenty of warnings about deprecated procedures and largely works.
Just compiled in (k)ubuntu 18.04, get a zip with the files from my storage - about 40 MB with all those borders & effects.

The 4 plugins go in ~/.config/GIMP/2.10/plug-ins The 4 folders go in ~/.config/GIMP/2.10 (along with all the other folders)
What does not work - the simple border, the changes to the Gimp 2.10 clipboard cause an error.
If a simple border is needed there are other ways. Use an
edge mask. Easy to apply with a couple of simple scripts and some greyscale images. You could adapt those beautify border pngs to edge masks.
Details of that are here:
