Comment 15 for bug 1490762

A good way to check the setup is to configure with cmake, then run ccmake ../ (just like cmake). It will bring up a curses interface with every configuration option available, and its value (if any). Be sure to hit 't' for advanced mode.

There are a few more paths than you probably realize that need to be explicitly curated. Of particular interest that seems to often pick up the homebrew path instead is a value weirdly called '_filename'. It's the location of the wx/version.h file, and often finds the wrong one.
