A notice is good but does not really solve the issue right? If you need to
have 1.x on your computer for whatever reason, you get crashes anyway when
running the tests.

I like Holger's option b:

Not sure if this works, but could you use multiprocess to import opencv and
run a function known to fail in 1.x in a separate process. Then if it works,
write something to a file, and read that file. If you avoid any shared
objects this may work.

Alternatively, locate the opencv header somehow, and parse it.

Cheers,
Ralf
