Back in 2014 I made some error reporting changes in 25333a2 (#3986), to do with reporting the exact boost library that was not being found. These were recently (unintentionally, I assume) removed in aa85dcf (#13095) by @fanquake.

I'm not sure how much of a problem this is, but wanted to create an issue nevertheless because these this error still gets reported all the time and for troubleshooting it was useful: #3219 (comment) .

If people feel this is worth it it'd be trivial to re-do the change.
