[vtk-developers] CMake 2.6

[Francois Bertel]

Even if everybody agree, you cannot start by changing requirement from
one day to another.


I think it will also impact ParaView3 and KWWidget.


3 steps have to be performed in the following order:

1. all the dashboard machines for VTK, ParaView3 and KWWidget have to
be upgraded to at least cmake 2.6.3.


2. add a warning for a couple of weeks with the expected date for the
switch to cmake 2.6.3, like


# VTK will require CMake 2.6.3 starting August 15th 2009
IF("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}" LESS 2.6.3)
 MESSAGE(WARNING "VTK will require CMake 2.6.3 starting August 15th
2009. Please update your CMake and this message will go away.")
ENDIF("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}" LESS 2.6.3)


3. At the announced date (August 15th 2009 in my example), change the
first line to:

cmake_minimum_required(VERSION 2.6.3)
