libANGLE-shared.dylib needs INSTALL_PATH when building Catalyst roots
Created attachment 423692 [details] Patch
Note that there are important steps to take when updating ANGLE. See https://trac.webkit.org/wiki/UpdatingANGLE
I verified this puts the dylib at /System/iOSSupport/System/Library/PrivateFrameworks/WebCore.framework/Versions/A/Frameworks/libANGLE-shared.dylib in the root. WebCore roots build to /System/iOSSupport/System/Library/PrivateFrameworks/WebCore.framework so I think that's the right location. WK_USE_ALTERNATE_FRAMEWORKS_DIR is only YES in iosmac builds because only WK_ALTERNATE_FRAMEWORKS_DIR_iosmac is defined in the ANGLE project, so this shouldn't break anything else.
