If you don't want to do that, you still can set that property manually, using e.g.:<br>
<br>set_source_files_properties( ${TARDIR}/t1 ${TARDIR}/t2 PROPERTIES GENERATED TRUE )<br><br>you then can use those files in a normal add_library or add_executable command. if you use the first approach (listing all files in the OUTPUT list), you don't even need the custom target, since CMake then will know how to "create" these files (by invoking the custom command).<br>

<div>Is there any way by which we just give the name of folder where files has extracted and add_library command will take it by some means it is becoz if we dont know what files will be genrated inside that folder or if there are large no.of files then listing them in OUTPUT is really cumbersome..</div>
