Yes I also tried with absolute path but it doesn't change anything. 
That's the only target I have:

add_executable(Z102A ${SOURCES} )
where:
set (SOURCES
        ${SOURCES_SourceXXYYFiles}
        ${SOURCES_HeaderXXYYFiles}
        ...
       ${SOURCES_Cfg}
      ....................
)


  set (SOURCES_HeaderXXYYFiles
        ./ASIC.H
        ./BaseTypes.h
        ./HAL.h
        ./IOPort.h
        ./usb2spi.h
        ./BuildNumber.h
)
set (SOURCES_Cfg
        ../../Cfg/AisTestData.cpp
        ../../Cfg/AisWin32Data.cpp
        ../../Cfg/AlphaKeybConfig.cpp
        ../../Cfg/AlphaKeybConfig.h
        ../../Cfg/BuildConfig.h
        ../../Cfg/Config.cpp
        ..........
   )
and Config.cpp includes BuildNumber.h. Maybe should I add an explicit 
dependency in some ways?
