[CMake] dependlocal problem

[William A. Hoffman]

You might be able to get around this with
 INCLUDE_REGULAR_EXPRESSION, if you set it to
a regex that includes everything but .moc then
cmake depend won't depend on the .moc file and the
problem should go away.

In this case it does have a rule to generate it so the dependlocal rule should not be added.  Please submit this as a bug report.
