is undergoing a transition to Qt, which happens to be supported to be
built with this library on Solaris, I began to rebuild Slicer's whole
tool-chain with stdcxx.

Looks like some sort of new line processing issue.

CMake Error at Modules/AtlasCreator/CMakeLists.txt:89 (add_library):
   Target "AtlasCreator" links to item "RemoteIO

   " which has leading or trailing whitespace.  This is now an error 
according
   to policy CMP0004.

CMake Error: Parse error in cache file 
/ufsbckp/head-64-slicer/apache/Slicer3-build/CMakeCache.txt. Offending 
entry: ;general;SlicerBaseLogic


Can you put the file 
/ufsbckp/head-64-slicer/apache/Slicer3-build/CMakeCache.txt on line as well?

I am guessing that \n is doubling for some reason...
