</div>You don't understand the problem, as long as FILES is empty, the<br>
foreach() loop will not run and hence your hostFiles variable will not<br>
be set. add_executable needs _at least_ 2 arguments, the name of the<br>
target and at least one source file. You only supply 1 argument, the<br>
target name, because your cmake variable is empty (or not set at all).<br>
You need to supply actual source files.<br>
