Loading AU plugins from non-standard locations?

Can JUCE be made to load AU plugins from someplace other than ~/Library/Audio/Plug-Ins/Components or /Library/Audio/Plug-Ins/Components? I’m trying to build and test AU plugins within a corporate testing framework that won’t let me write to those directories. I’m not crazy about the idea of using non-standard locations, but trying to perform due diligence about all options.

This is actually more specific to macOS than JUCE

You find AudioUnits through the AudioToolbox framework via AudioComponentFindNext(), which takes an AudioComponentDescription rather than a file location

I made a little plugin manager app in JUCE for my own usage once and trying to handle AudioUnit file locations was just not an option
