Thankyou Thomas, it works now... Another issue I was faced with the first
script is, it assumes that the dlls are in the lib folder of Qt (I think
you build qt from source). I have downloaded the prebuilt Qt library, in
that the dlls are in the bin folder. I modified the macro you have given,
as below...
MACRO(GetDLLs DEBUG_NAME RELEASE_NAME)
#Copy Debug dlls
LIST(APPEND ${DEBUG_NAME} "${QT_BINARY_DIR}/QtGuid4.dll")
...
