error during build in Ubuntu 14.04 with MKL library

[tqchen]

You want to add MKL to the include path. Find the path to the MKL library header file and add it by something like -I/path-to-mkl-header

You may also want to add the MKL lib file to -L and LD_LIBRARY_PATH

Sorry I know the path but I don't get where exactly should I put the path in (somewhere in the makefile?).
Could you please give me more detail? I am very new to Linux.

Look at the LDFLAGS portion below ( snippet from sample Makefile). Here -L/opt/OpenBLAS/lib/ indicates to include /opt/OpenBLAS/lib/ which is where my blas library files are

ifeq ($(blas),1)
 LDFLAGS= -L/opt/OpenBLAS/lib/ -L/opt/nvidia/cuda/lib64  -lm -lcudart -lcublas -lcurand -lz `pkg-config --libs opencv` -lopenblas
 CFLAGS+= -DMSHADOW_USE_MKL=0 -DMSHADOW_USE_CBLAS=1
 LDLIBS=/opt/OpenBLAS/lib/
else
 LDFLAGS= -lm -lcudart -lcublas -lmkl_core -lmkl_intel_lp64 -lmkl_intel_thread -liomp5 -lpthread -lcurand -lz `pkg-config --libs opencv`
endif
```shell

Add source /opt/intel/bin/compilervars.sh to your .bashrc will solve most MKL path issues.

Thanks @hrishikeshvganu and @ziyuang but I still cannot solve the problem.

The extra line in my .zshrc is source /opt/intel/bin/compilervars.sh intel64, and

$ cat /etc/ld.so.conf.d/intel.conf
