[SCIP] problems with installing SCIP on macOS

[Antonio Frangioni]

Hi.

Thanks for the quick answer.

> It looks like you have an incomplete ZIMPL installation in /usr/local, because /usr/local/lib/cmake/zimpl/zimpl-targets.cmake seems to be there, but /usr/local/lib/libzimpl.a is missing. Then the detection of ZIMPL fails.
> I suggest either removing /usr/local/lib/cmake/zimpl, adding -DZIMPL=off to SCIP's cmake call

Thanks. This worked for me.

	Best
