[vtkusers] Compiling VTK in Cygwin with -mno-cygwin

[William A. Hoffman]

The problem is that cmake is reporting cygwin unix as the build environment.
One thing you could try is to run the WINDOWS CMakeSetup and put the cygwin
compilers in your PATH when you run it.   Then select Unix Makefiles as the
generator.   Then add the -mno-cygwin flags.   Then it would be closer to 
the mingw compiler, and stuff should work.
