[CMake] Dealing with custom command outputs when using clean

[Willy Lambert]

Dear Petr,

Thanks for this instant support :D

The correct line was :
	set_directory_properties(PROPERTY ADDITIONAL_MAKE_CLEAN_FILES
${EXECUTABLE_OUTPUT_PATH}/${EXEC_NAME}.debug)

So you are rigth, the directory is the current one (in this case) and
the target file must be surround by the target output dir. I also used
set_duirectory_properties since I think it's a clear wrapper to
set_property(DIRECTORY .)
