Something like this:

#########################################################################
# Disallow in-source build
STRING(COMPARE EQUAL "${ParaView_SOURCE_DIR}" 
  "${ParaView_BINARY_DIR}" INSOURCE)
IF(INSOURCE)
  MESSAGE(FATAL_ERROR "ParaView requires an out of source Build. Please create a separate binary directory and run CMake there.")
ENDIF(INSOURCE)
