It's also GROMACS 5.1.2 not the 2018 you reported trying to install. You
need to make sure your terminal has been given access to the GROMACS that
you want to use (see that part of the install guode.).
Also, your CMake line tried to use OpenCL which is not what you want for
running on an Nvidia GPU (even though you can get it to work).
