Undefined references to mkl objects

I'm attempting to compile OpenCV with Intel MKL 2017.0 on Ubuntu 16.04.1 with , but I keep running up against the following errors at compile time:

/opt/intel/compilers_and_libraries_2017.1.132/linux/mkl/lib/intel64_lin/libmkl_sequential.so: undefined reference to `mkl_spblas_lp64_ccsr0ttluc__svout_seq'

I have installed Intel MKL and I have the following in my zsh startup script:

source /opt/intel/mkl/bin/mklvars.sh intel64

I also have the following in /etc/ld.so.conf.d/intel_mkl.conf :

/opt/intel/lib/intel64
/opt/intel/mkl/lib/intel64

CMake manages to find MKL and reports:

-- Found MKL 2017.0.1 at: /opt/intel/mkl
-- LAPACK(MKL): LAPACK_LIBRARIES: /opt/intel/mkl/lib/intel64/libmkl_core.so;/opt/intel/mkl/lib/intel64/libmkl_intel_lp64.so;/opt/intel/mkl/lib/intel64/libmkl_sequential.so;/opt/intel/mkl/lib/intel64/libmkl_core.so;/opt/intel/mkl/lib/intel64/libmkl_intel_lp64.so;/opt/intel/mkl/lib/intel64/libmkl_sequential.so;/opt/intel/mkl/lib/intel64/libmkl_core.so;/opt/intel/mkl/lib/intel64/libmkl_intel_lp64.so;/opt/intel/mkl/lib/intel64/libmkl_sequential.so;-lpthread;-lm;-ldl
-- LAPACK(MKL): Support is enabled.

CMake also lists:

--     Use OpenCL:                  YES

What am I missing? Are there any additional compile flags I should be specifying?
