One of the areaDetector optional plugins is in areaDetector/ADPluginEdge. Its CONFIG_SITE contains this line:
It thus installs its library, dbd, and .template file into ADCore.
Much to my surprise running “make uninstall” on EPICS 7 at the top level of ADPluginEdge deletes the ADCore/configure directory! Needed to run “git checkout master .” to recover it.
I have removed that line from CONFIG_SITE because I don’t think it is what we really want to do anyway, but this definitely seems like a dangerous bug in EPICS 7. That directory could have had local edits that were lost.
