[SCIP] GCG errors while running detect

Wed Jul 11 03:48:09 CEST 2018

Hi.

I just got GCG 3.0 installed and did point to hMetis in the cmake.

It seems like it found it OK, but on my first try (solving a standard MIP
p0201), I get a similar error in log related to hMetis:
[/LOG_DATA/SCIP/scipoptsuite-6.0.0/gcg/src/graph/hypergraph_def.h:225]
ERROR: Could not open file <gcg-r-1.metis.Db48pk.part.3> for reading

Thanks,
