My perspective is very simple. I am a cygwin package maintainer.
So I expect that cmake on cywin builds cygwin programs, not something else.

When I want to compile mingw-programs, I use the 
mingw64-i686-gcc cross compiler (cygwin to mingw)
not gcc ( cygwin to cygwin).

if cmake don't change it useless for porting to cygwin.

And this is really blocking the port of a lot of packages.

I don't like to build my own version of cmake to overcome
the current setting of the cmake cygwin package.
