# VTK_GET_SOURCE_REVISION_AND_DATE
# Get vtkVTKVersion's source revision and date and store them in
# ${revision_varname} and ${date_varname} respectively.
#
# This macro can be used to require a specific revision of the VTK
# library in between version changes.
# For example:
#   INCLUDE("${VTK_CMAKE_DIR}/VTKVersionMacros.cmake")
#   VTK_GET_SOURCE_REVISION_AND_DATE(source_revision source_date)
#   IF(source_revision LESS 1.4)
#    MESSAGE(FATAL_ERROR "Sorry, your VTK library was last updated on ${source_date}. Its source revision, according to vtkVTKVersion.h, is ${source_revision}. Please update to a newer revision.")
#   ENDIF(source_revision LESS 1.4)
