Comment (by jralls):

 No you didn't, you just broke your port. You need to patch CMakeLists.txt
 so that GnuCash will actually link Webkit2 on Macs. It currently doesn't
 because the last time I tried with WebKit 2.18 it wouldn't render the
 javascript-generated graphical reports. Debugging showed libjavascript
 running in a separate thread and apparently not connecting back to the
 GtkWebKitWebView. I wasn't able to figure out why not and got no
 assistance from the WebKitGtk folks so I reverted MacOS builds to WebKit1.

 The X11 version may not have the problem; if that works by all means
 submit a PR to change CMakeLists.txt to link WebKit2 on Mac with X11.
