It should work with CMake 2.8.2 and higher:

   http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=2c1a01dc

in combination with VTK 5.6.0 and higher:

   http://vtk.org/gitweb?p=VTK.git;a=commitdiff;h=19852427

Note that the VTKConfigVersion.cmake file's job is to find a VTK
that is "compatible" with the requested version, as documented
by the find_package command.  The decision that this particular
implementation in VTK makes is that a matching major.minor number
is considered compatible and otherwise not.  Therefore

   find_package(VTK 5.8 REQUIRED)

will not find current VTK master which is 5.9.  It will find a
VTK 5.8 installation though.
