That's your problem, right there: you haven't set the Windows PATH to
find the Cygwin 'make'.  The directory /usr/bin/ doesn't really exist
on your filesystem, as far as Windows is concerned, it is an illusion
created by Cygwin.  Find its real name (something like
C:\Cygwin\usr\bin perhaps?) and add it to the Windows PATH.  Then you
will be able to call it from "M-x compile" and from Eshell alike.

Alternatively, install the Cygwin build of Emacs, which will find
'make' like the Cygwin shell does.

IOW, mixing Cygwin and native Windows tools needs extra work.
