CMake fails at HEAD

[ikitayama]

I'm on the HEAD of master branch:

commit 3eda4280f9e44d8f2742b70ab254bcf1912f17ad
Author: nrnhines <michael.hines@yale.edu>
Date:   Wed Aug 12 18:02:23 2020 -0400

    Support for FOR_NETCON (#355)

    * Framework to support FOR_NETCONS construct with CORENEURON.
    * Update correct mod2c master with necessary support
    * Implement setup_fornetcon_info
    * Remove _type redefine macro to avid issues with compile like GCC v8.3
    * docs target are not added if coreneuron is used as submodule
    * After embedded simulation, copy weights back to NEURON NetCon.

Sorry, I wasn't checking out the code with the --recursive option.

Thanks @ikitayama ! This should have been automatic i.e. without --recursive. I am fixing this in better way as part of #368.
