Your previous post never made it to me, either cygwin or cygwin-apps lists,
their archives, or mail-archives'.
Please check the archives and your email and repost.

Meanwhile, that info likely comes from:

$ tail -vn15 /lib/pkgconfig/libcurl.pc
==> /lib/pkgconfig/libcurl.pc <==
#

exec_prefix=/usr
libdir=${exec_prefix}/lib
includedir=${prefix}/include

supported_features="SSL IPv6 UnixSockets libz brotli AsynchDNS IDN PSL NTLM

Name: libcurl
URL: https://curl.haxx.se/
Description: Library to transfer files with ftp, http, etc.
Version: 7.71.1
Libs: -L${libdir} -lcurl
Libs.private: -lnghttp2 -lidn2 -lssh -lpsl -lssl -lcrypto -lldap -llber
-lbrotlidec -lbrotlidec -lz
Cflags: -I${includedir}

it looks like your git build should be using Libs for dynamic builds and adding
Libs.private for static builds, so please check whether and how that is used,
and whether you have at least the runtime libs installed, and also the -devel
packages if you are building statically.
Static builds are not uncommon for test versions of package modules, as that
avoids issues with having to install package or dependency dynamic libraries
that may not yet be ready for prime time.

I have never had any problems with packages using pkgconf/-config and never had
to look into it, so anyone with more knowledge and experience of issues there
should feel free to contribute.

Trying to build with cygport:

- it died silently as I did not have bash-completion-devel installed: could you
please perhaps move that pkg-config line into src-compile, so that cygport can
at least run, check, and complain about missing dependencies?

- it complains that perl(DBD::SQLite) perl(IO::Pty) are not installed - how do
these and your other perl module dependencies map to Cygwin packages?
I also mean that in general - how can I map a perl module to a perl package and
vice versa - for future info?
