Deprecated since version 3.14: This command was originally added to support Qt 3 before the add_custom_command() command was sufficiently mature. The FindQt4 module provides the qt4_wrap_cpp() macro, which should be used instead for Qt 4 projects. For projects using Qt 5 or later, use the equivalent macro provided by Qt itself (e.g. Qt 5 provides qt5_wrap_cpp()).
Manually create Qt Wrappers.
qt_wrap_cpp(resultingLibraryName DestName SourceLists ...)
Produces moc files for all the .h files listed in the SourceLists. The moc files will be added to the library using the DestName source list.
Consider updating the project to use the AUTOMOC target property instead for a more automated way of invoking the moc tool.
