[CMake] CTEST and build errors

[Milan Dorak]

How does CTest recognize build errors ?
I'm using utility which compile .xml file into .bin, it has output like 
this:

  Configuration compilator version 2.10
  12:09:41: Compiling: 
/home/dvorakm/trunk/modest.src/_st/ciernant/cs/cfg.lin.1oo1.xml to 
/home/dvorakm/trunk/appl/CS_APP_1oo1/build/appl.src/cfg.bin
  12:09:41: Generating map file: 
/home/dvorakm/trunk/appl/CS_APP_1oo1/build/appl.src/cfg.bin.map.xml
  12:09:41: Compilation done

  Configuration compilator version 2.10
  12:09:41: Compiling: 
/home/dvorakm/trunk/appl/CS_APP_1oo1/build/clcfg.xml to 
/home/dvorakm/trunk/appl/CS_APP_1oo1/build/appl.src/clcfg.bin
  12:09:41: Generating map file: 
/home/dvorakm/trunk/appl/CS_APP_1oo1/build/appl.src/clcfg.bin.map.xml
  12:09:43: Compilation done

CTest marks each line as build error, I can't figure out why
