With sources, hopefully, as per the GPL...

As long as cygwin1.dll is found (in the PATH).

Technically -- anywhere in the PATH.  However, if you aren't the only one
sending them a cygwin1.dll, or if they have Cygwin installed, they'll have
problems with multiple copies of the DLL on their system.  You could
provide a script that attempts to detect cygwin1.dll in the PATH (although
that might raise some versioning issues).

It is, however, best to recommend that they install Cygwin themselves
before running your application.
HTH,
