Meanwhile, that info likely comes from:

it looks like your git build should be using Libs for dynamic builds and adding
Libs.private for static builds
If you look at configure.ac in the git sources, you'll see that it uses
curl-config, not pkg-config. The former reports:
$ curl-config --libs
-lcurl -lnghttp2 -lidn2 -lssh -lpsl -lssl -lcrypto -lldap -llber -lbrotlidec
-lbrotlidec -lz
Yaakov's build of earlier versions of curl used a patch 7.33.0-libdeps.patch to
prevent the unnecessary libs from being listed. He even had a comment at the
beginning of the patch, explaining the reason for it: "These are needed only for
static linking, but we build with --disable-static".
I try to avoid looking at autotools plumbing if I can possibly avoid it! ;^>
Someone cleaned up the approach used, as the patch did not apply and was
dropped.
My point is that the patch shouldn't have been dropped. It should have been
modified to apply to the updated sources. (I've done this. See the attached.)
As Yaakov wrote, the patch is needed to prevent 'curl-config --libs' from
including libs that are only needed for static linking.
With the modified patch applied, curl-config gives the expected result:
$ curl-config --libs
-lcurl
If you look at my later post, cygport git build and tests worked for me with no
problems other than at first missing some package build dependencies
Those were not really build dependencies. They only appeared to be needed
because 'curl-config --libs' erroneously included libs that are only needed for
static linking.

These are needed only for static linking, but we build with --disable-static
