Undefined reference to af::array::array

I am using the QR factorization from ArrayFire in my code. My code is similar to the QR factorization example given on the ArrayFire documentation website.

In my Makefile, I have linked -lafcpu -lafopencl -lafcuda -laf as well as the path to them.

The only undefined reference I am receiving is: undefined reference to af::array::array<double*>(long long, long long, double* const*, af_source)

Is there anything else that I should link as well?
