The problem is caused by adding some include and library to makefile.config or adding some environment variable in the user account which are related to opencvs.
One should eliminate the one which actually cause the problem and delete it. And re-login is required to solve this.
But in general, add matlab runtime library to environment variable or makefile.config will cause this problem during compiling caffe.
