Here is another version of that same file, from the same sources, when CMake is
compiled with STLport4, for reference (this is the file from my current
Slicer3-build dir):
www.orl.szote.u-szeged.hu/~attila/Slicer3Config-stlport.cmake
OK, I think we found the problem...

Macro in CMake\Slicer3PersistenceMacros.cmake
http://viewvc.slicer.org/viewcvs.cgi/trunk/CMake/Slicer3PersistenceMacros.cmake?rev=6774&view=log
Seems that it is from a work around for CMake older than 2.6:
#-----------------------------------------------------------------------------
# Temporary hack to set/get persistent values accross subdirs until 2.6
comes
# Neither set_source_file_properties nor set(... INTERNAL FORCE) would work
#-----------------------------------------------------------------------------
macro(slicer3_set_persistent_property property_name)
set(_file "${CMAKE_BINARY_DIR}/persistent/${property_name}")
file(WRITE "${_file}" "${ARGN}")
#set(__${property_name} ${value} CACHE INTERNAL "" FORCE)
endmacro(slicer3_set_persistent_property property_name value)
#-----------------------------------------------------------------------------
macro(slicer3_get_persistent_property property_name var_name)
set(_file "${CMAKE_BINARY_DIR}/persistent/${property_name}")
if(EXISTS "${_file}")
file(READ "${_file}" ${var_name})
else(EXISTS "${_file}")
set(${var_name})
endif(EXISTS "${_file}")
#set(${var_name} ${__${property_name}})
endmacro(slicer3_get_persistent_property property_name var_name)
You could change that macro to not use file WRITE. IF you want to
track this down in CMake, you could try some small examples with a CMake
built with both versions of stdc++. You could use file(WRITE and
file(READ to write/read some lists from a file.
But, sounds like it is time to remove the temporary hack in Slicer...
