[CMake] How to copy dependent files

[Tron Thomas]

I have tried a different approach that has been more successful:

add_custom_target(CopyXML ${CMAKE_COMMAND} -E copy_directory
	${CMAKE_CURRENT_SOURCE_DIR}/XML	${EXECUTABLE_OUTPUT_PATH}

add_dependencies(UnitTest CopyXML)

This will always copy the files whether they need to be updated or  
not, however I cannot think of anything else that will cause the file  
to get copied.

Another problem is that when I build this target from an IDE like  
Apple's Xcode, the file are copied to ${EXECUTABLE_OUTPUT_PATH},  
however the built executable is copied to ${EXECUTABLE_OUTPUT_PATH}/ 
Debug when building the debug version the application.

How can I get the copied files and built executable to appear in the  
same directory.
