Well, yes, ideally the project would use a cross-platform toolkit for
its GUI instead of using X11 directly. So in your case there are two
options:

- install cygwin, X11 for cygwin and cmake for cygwin, then build inside
  cygwin. Also all other users will then have to install cygwin to use
  this project on win32

- port the code of your project that uses X11 to Win32 API or some
  cross-platform GUI toolkit, then you won't need cygwin.
