mkl_cluster_sparse_solver.f90 missing

I'm running parallel_studio_xe_2020.0.088 on CentOS 7.  I'm trying to compile the PARDISO example for complex unsymmetric matrices using the following:

make libintel64 mpi=intelmpi compiler=gnu interface=lp64 ompthreads=8 mpidir=/opt/intel/impi/2019.6.166/intel64/bin examples=cl_solver_complex_unsym

I get the following output

make ext=a  run
make[1]: Entering directory `/opt/intel/compilers_and_libraries_2020.0.166/linux/mkl/examples/cluster_sparse_solverf'
make[1]: *** No rule to make target `/opt/intel/compilers_and_libraries_2020.0.166/linux/mkl/include/mkl_cluster_sparse_solver.f90', needed by `_results/gnu_intelmpi_lp64_intel64_a/mkl_cluster_sparse_solver.o'.  Stop.
make[1]: Leaving directory `/opt/intel/compilers_and_libraries_2020.0.166/linux/mkl/examples/cluster_sparse_solverf'
make: *** [libintel64] Error 2

Indeed when I look in /opt/intel/compilers_and_libraries_2020.0.166/linux/mkl/include/, the file mkl_cluster_sparse_solver.f90 is not there.  I have an older 2018 version of the sute, and it's not there either.    

What I'm I missing?
