Sorry if this has been answered before, I can't find a relevant mail.
We've built oiio with embedded plugins and now we're attempting to override the
exr plugin with a customized one.
Unfortunately the plugin_searchpath string passed to ImpageInput::create() does
not appear to take precedence during the cataloging of available plugins which
means the embedded openexr plugin appears to always be found first.
Is this the expected behavior or am I doing something wrong?
The custom exr plugin is handicapped so the plugin's open() method will produce
an assert error, but no assert is occurring so I'm assuming the embedded
openexr plugin is getting called instead.

Thanks for any help,
