A more proper way to work with this kind of install would be to add /opt/wxWidgets/lib to Audacity's rpath. Or, if any and all wxWidgets apps should use the libraries there you could add the location to ldconfig.

I think it's rather the contrary, i.e. that KDevelop resets that variable.

IIRC you can associate an environment profile to your debug configuration, and set your variable(s) that way.

An alternative approach would be to launch Audacity like you would normally (except the debug build), and then attach KDevelop's debugger to the running process. This is typically faster if you're not debugging the startup phase itself, sometimes a lot faster.
