There are several hardcoded paths and assumptions made in order to get this working on Travis CI. New tooling is using cmake for cross platform builds and as such is not easy to use with an autotools based system.
It's not ideal but better than nothing.
Some Linux distributions are dropping webkitgtk support which is needed for wxWebView to work. This will build a second wxWidgets cache that has no webview support in order to test new code.
This reduces the size of files to be cached between builds by the CI system. The scripts are flexible enough so they can also be used by developers locally.
