Using git.cygclass also handles conversion to tar used as SRC_URI and fixing up 
the SRC_DIR.

After `inherit git`, you could add:

MINTTY=https://github.com/mintty/mintty/raw/refs/heads/master/tools/
SRC_URI+=" $MINTTY/getnoto "

or

MINTTY_TOOLS=https://github.com/mintty/mintty/raw/refs/heads/master/tools/
SRC_URI+=" $MINTTY_TOOLS/getnoto "

and so on, or local file:// equivalents, or use git submodules.

It is usual to attach the .cygport as text/plain so we don't have to download 
and unpack the tar to be able to comment.

It does use --depth 1: you could define your own git() { ... } function in your 
.cygport(s) to add --sparse after "$@" if $@[1] == clone, although I don't 
*KNOW* that git uses or supports GNU style flexible getopt?
It could also DTRT on checkout, submodule, and so on, if required.

It does take a while to tar ~0.5GB, and unpack and copy that into ~1.5GB 
{origsrc,src,temp} of repo, which if installed and packaged could become ~2.5GB 
workspace!

Then set it to "Shells Graphics" perhaps instead, as Cygwin seems to categorize 
terminal emulators as "Shells".

You may then want to select only some resolution(s) of some glyph variations 
(single codepoint only?) and convert to usable size and more compact format such 
as webp using say ImageMagick `mogrify -path webp -format webp svg/*.svg` which 
shrinks svg from 40MB to 16MB, png/512 from 100MB to 40MB, and similar.
