scip_exception.hpp is non-free code

[hlieberman]

Hello.

In the process of packaging Numberjack for Debian, I found that scip_exception.hpp appears to be copyrighted code that isn't licensed under any compatible F/OSS license.

It appears that scip_exception.hpp is straight copyrighted; I have not been able to find any references to it being licnesed as part of SCIP (under the ZIB Academic License) which would at least permit linking against an LGPL program like Numberjack.

It should be removed, or the copyright holder should license it under a F/OSS license.
