[SCIP] Building scipampl in scipoptsuite v5.0.0?

[Matthias Miltenberger]

Hey Carleton,

I just set up a simple CMakeLists.txt for out AMPL interface.
It works just like any other SCIP application or example when you put it 
into `interfaces/ampl`:

     mkdir build
     cd build
     cmake .. -DSCIP_DIR=<path/to/scip/build>
     make
     enjoy!

The AMPL interface must have went under our radar when we introduced the 
CMake build system. This will be included in the next bugfix release.

cheers
Matthias
