[PATCH] Failure to compile wxWidgets library on OS X Yosemite

[Doménique]

I upgraded my mac from Mavericks to Yosemite yesterday and I found that wxWidgets fails to compile a WebView component as Apple has adjusted WebKit-related headers. So this is really an upstream problem with wxWidgets about to be fixed in v3.0.3 (not released yet). As 0 A.D. currently uses v3.0.1, this ticket merely serves as a reminder to have a look at the library once it's released.

• A temporary fix is available for Yosemite by simply pointing wxWidgets to the legacy WebKit header, a one line change according to this webpage: ​http://goharsha.com/blog/compiling-wxwidgets-3-0-2-mac-os-x-yosemite/
• v3.0.3 alters the code to work with the new header, but in the mean time this is a quick fix to get it working.
• Issue: on recompiling libraries, the build-osx-libs.sh file extracts and overwrites any such fixed made, so currently the one line change has to be made between extraction and compilation. Not handy, but keeps you busy as wxWidgets compiles ;)
• 0 A.D. currently patches something on the library source. That issue is resolved upstream with a newer version as well (a quick look at the ticket suggests it is).
• A solution for 0 A.D. could be to add the one line fix into the patch (with some gatekeeper code for OS X 10.10 only), and both issues may be resolved when wxWidgets v3.0.3 is released.

For the record, the compilation was done with Yosemite-specific Command Line Tools. I did not alter the minimum OS target.

Other than this issue, compilation completes (with some linker warnings though). I had a quick look and everything seems to work fine in Yosemite :)

due atlas doesn't use webkit(or webview) we could disable this features.

I tested in my osx yosemite(by accident)

Disabling not used features would probably a better approach.
