I have a problem running scip with cplex! when I run "make LPS=cpx ZIMPL=false", I got the following error: make LPS=cpx ZIMPL=false
make: * No rule to make target ~/scipoptsuite-3.0.2/scip-3.0.2/lib/liblpicpx.linux.x86_64.gnu.opt.a', needed bybin/vrp.linux.x86_64.gnu.opt.cpx'. Stop.

Can someone please help me?

Please be more specific what the second part of your question means, don't you succeed creating soft links? Following the answers below, soft link creation should not be an issue, because SCIP does this for you. Please mark an answer which solves your problem. - Gregor

It seems that you are trying to build the VRP example of SCIP. Before you can do this, you need to build SCIP itself with the exact same options, in particular also with CPLEX as LP solver. You can even do this from the VRP example directory by using the Makefile target 'scip', i.e., make LPS=cpx ZIMPL=false scip.

it seems that you try to compile the VRP-example of SCIP before ever compiling the main SCIP. You need to first compile the main SCIP, i.e., go to the main SCIP-directory and run your make-command. This will create the necessary library liblpicpx.linux.x86_64.gnu.opt.a, which the example depends on. Note that the make-command automatically asks you for the include and library paths. If not, you can force this behaviour by calling 

make LPS=cpx ZIMPL=false links

More Makefile options are explained in the documentation.
