eventually it is a problem of the current cmake-2.6.4

Using the previous cygport cmake-2.8.1-11=20
and with only a patch at
  Utilities/vtkpng/pngconf.h

to remove the wrong=20
  #if defined(__CYGWIN__)
  ...
  #endif
at row 104-147

plus a small additional modification during build at
Examples/Charts/Cxx/CMakeFiles/GraphItem.dir/link.txt
to help VTK to find one of its dll's

I was able to compile the full vtk-5.6.0
with :
-----------------------------------------------
98% tests passed, 7 tests failed out of 371

Total Test time (real) =3D 1910.59 sec

The following tests FAILED:
          1 - HeaderTesting-Common (Failed)
         19 - TestPolynomialSolversUnivariate (Failed)
        127 - SLACReaderLinear (Failed)
        128 - SLACReaderQuadratic (Failed)
        129 - SLACParticleReader (SEGFAULT)
        228 - HeaderTesting-Widgets (Failed)
        265 - TestSplineWidget (Failed)
Errors while running CTest
------------------------------------------------
=20
and the dll's are correctly linked with cygGL-1.dll
