[Scip] scip-3.0.1: recipe for target `scipbinary' failed with visual c++

[Mengda Wu]

OK. It works if I manual copying of soplex-1.7.1/src to
scip-3.0.1/lib/spxinc.

I found the problem. In scipoptsuite-3.0.1/Makefile.doit:

$(SOPLEXINCLINK):    softlinkmsg $(SCIPDIR)
        @rm -f $@
        @$(LN_s) -s $(SOPLEXINC) $@

The extra "-s" after $(LN_s) makes "cp -r" still make symlinks. You need to
remove it.

Also, for all the "rm -f" in Makefile.doit to remove directory. It's better
to use "rm -rf" to make it work.

Thanks,
Mengda
