Correct. > I'm not quite sure how the dependencies are handled between directories. > Brad ? Custom commands are only hooked into targets in the same directory in which they are defined (not even subdirectories). > I guess then one way would be to add a helper target > add_custom_target(CREATE_DBUS_STUFF) > which creates all the dbus xml interfaces, and have all the targets which > need > these interfaces depend on this helper target. Using a target-level dependency is the correct approach. Having the rule to generate the file in more than one target could result in corruption during parallel builds. > OTOH, if other targets need some part of what is built when kmail is being > built, then it doesn't seem to be that wrong to make them depend on kmail (or > the helper target). Any approach that puts the generation rule in a single target on which all other targets that use the file depend is correct. Avoiding a helper target in favor of a target on which a dependency must be added anyway is probably good. -Brad _______________________________________________ Kde-buildsystem mailing list [email protected] https://mail.kde.org/mailman/listinfo/kde-buildsystem
