Hello!
Um no. That's not what Cygwin is for. If you want something that
originated on Linux to be made available for Cygwin, you're going to
need to build it yourself. There are ample hints that explain how to
do this.

You might want to ask on the Apps list to see if anyone has considered
porting MySQL to Cygwin, and what happened during the process.
