Yes this is what I do. And indeed there is a  big Makefile with 730 lines
  created in my build directory, that builds the software.
The source directories get polluted only with the 5 lines Makefiles 
attached in my previous mail.
It seems only one thing related to cpp-utils is writing where it should not.
All binaries are built in my build directory.
  I do have a full hierarchy of CMakefiles directories that contain what 
they should contain.
The top level build/CMakefiles directory does contain the 
CMakeOutput.log file
but I can't make sense of what is wrong at which point.
It contains also a fille CMakeFiles/TargetDirectories.txt with the right 
directories
I list below the first 5 lines. They are correct and you can see there 
is a build directory
The source is in trunk

/home/vjf/workspace/merging/simsoc/trunk/build/libsimsoc/tools/debugger/CMakeFiles/debugger.dir
/home/vjf/workspace/merging/simsoc/trunk/build/examples/SerialISS/CMakeFiles/build_serial_iss.dir
/home/vjf/workspace/merging/simsoc/trunk/build/utils/ISC/CMakeFiles/isc.dir
/home/vjf/workspace/merging/simsoc/trunk/build/examples/TI_AM1707/CMakeFiles/ti-am1707.dir
/home/vjf/workspace/merging/simsoc/trunk/build/examples/SPEAr/CMakeFiles/spear.dir


The source directory (trunk) remains entirely clean,
except for these strange 5 lines Makefiles.
