[SCIP] Building scipampl in scipoptsuite v5.0.0?

[Stefan Vigerske]

Hi,

for some parts of the SCIP optsuite, there is no support with the cmake 
buildsystem. The AMPL Interface is one of these parts.
That is, to build the AMPL interface, the easiest is to also build SCIP 
with the classic buildsystem.

So that would be something like

# unpack optsuite
tar -xvzf scipoptsuite-5.0.0.tgz
cd scipoptsuite-5.0.0

# build it with Ipopt
make IPOPT=true

# Build SCIP AMPL interface
cd scip/interfaces/ampl
./get.ASL
cd solvers
make -f makefile.u
cd ..
make IPOPT=true


(I usually never use the optsuite makefile. If that doesn't ask you for 
the location of Ipopt, then do a make IPOPT=true in ./scip after 
building the optsuite and before building the ampl interface.)
