Bug 69997 – [Chromium] Reduce dependencies of ImageDiff to compile it for Android.

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Hao Zheng]

Make ImageDiff depend on webkit_support_gfx only. Build it as toolsets:host for Android.

This change is required to make ImageDiff for Android, and can benefit other platforms, too. On Android, most targets are built as toolsets:target. while ImageDiff needs to be built as toolsets:host. Currently, building the standalone target of ImageDiff depends on about 85 other targets (try  make ImageDiff'), which is inefficient. After the change, ImageDiff only depends on webkit_support_gfx, which in turn depends on libpng and zlib.

Sorry, I didn't try Debug build. Now I completely removed code dependent on JavaScriptCore.

I think we should just depend on wtf because it's pretty small.  Or are you trying to avoid having host and target in JavaScriptCore.gyp?

I would just include this on all platforms if a single platform needs it.

No, it's because wtf would depend on icu, which in turn would depend on others...
