[vtkusers] Building VTK 5.0.2 with CygWin

[David Cole]

For cygwin builds, you should use cygwin CMake... Are you? What does
cygwin say if you type "which cmake"...?

To build VTK with cygwin:
use cygwin CMake
use the "Unix Makefiles" generator

See the VTK dashboard scripts that are running on cygwin nightly to
see some examples of various CMake cache settings used for VTK cygwin
builds...

For example, this one:
http://www.vtk.org/Testing/Sites/ARRAKIS.kitware/Win32-cygwin/20070213-0300-Nightly/Notes.html

(Currently there is an issue with CVS HEAD VTK on cygwin regarding
snprintf. There is a developer aware of this situation and working on
it....)


HTH,
David

To fix this you might need to set the cache value of CMAKE_BACKWARDS_COMPATIBILITY to 1.4 or less. If you are writing a CMakeList file, (or have already set CMAKE_BACKWARDS_COMPATABILITY to 1.4 or less) then you probably need to include a CMake module to test for the feature this variable defines.
