Hi inkblotter,

At one point, I had 4 versions of wxWidgets installed (2.8, 2.9.4,
3.0.x & 3.x-git). To select one of them, I simply changed two
parameters passed to cmake:
- -DwxWidgets_CONFIG_EXECUTABLE=/path/to/wx-config-X.X
- -DwxWidgets_wxrc_EXECUTABLE=/path/to/wxrc-X.X

If I recall correctly, the parameters that GAL is picky about were
important in 2.8. Now, when I build 3.x-git, I simply use ./configure
and the defaults are fine (but please be sure that you have OpenGL
enabled).

Regards,
Orson
