Bug 137389 – [GTK] Do not generate a symlink in derived sources for every header in WebCore/bindings/gobject

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Carlos Garcia Campos]

We only need a symlink for static sources that are included in public generated headers, because they are added with as <webkitdom/WebKitDOMFoo.h> so they need to be inside a webkitdom directory. Also use proper targets and commands to create the symlinks only when needed instead of for every build.

This removes one of the targets that are always built, see bug #130075

I think there are a couple ways to make this a little cleaner. One is to use a macro and a list of file names (you could even omit the directories). The other is to use a single add_custom_command with multiple outputs and dependencies.

[Carlos Garcia Campos]

I guess I prefer the macro solution, not sure I will find the time to learn how to do that in cmake, though.

[Martin Robinson]

Let me see if I can find a few moments to propose something this weekend.

Simplified version using a foreach loop

Hope this is cleaner
