Cygwin supplies a number of ...krb5... packages from MIT reference sources.
Search packages from the link on the Cygwin home page e.g.
https://cygwin.com/cgi-bin2/package-grep.cgi?grep=krb5&arch=x86_64
which looks like there is only one krb5 source package krb5-1.15.2-2-src
viewable as:
https://cygwin.com/cgi-bin2/package-cat.cgi?file=x86_64%2Fkrb5%2Fkrb5-1.15.2-2-src&grep=krb5
which shows a number of patches, including Cygwin specific patches, and another
source package for krb5-auth-dialog.

Almost all Cygwin packages now use cygport for building (and packaging).
Download the krb5 source package, have a look at it, and how the packages are
built from the .cygport file.
Install the cygport package, maybe libkrb5-devel and sources, try a build, then
look at adapting that package build for your sources, if different.
