for dll runtime dependency see

$ cygcheck /usr/bin/lftp.exe

using a small script like
--------------------------------------------
#/!bin/bash
if [ $# -ne 1 ]
then
        echo "Usage : " $0 "file_name"
        echo "Find package dependency from dll dependency"
        exit 1
fi

a=1
for i in  $(cygcheck $1 |tr " " "^" | tr "\r" " " )
do
        echo  -n $i |tr "^" " "
        echo -n " =>  "
        b=$(cygcheck -f $(cygpath -u $(echo $i |tr  "^" " "))| tr "\r" 
" " )
        if [ -z $b ]
        then
          echo "??"
        else
          echo $b
        fi
done
----------------------------------------------------
you can directly look at the package dependency
