The above command opens the ccmake GUI. Press 'c' to configure. We now modify the necessary variables in the ccmake GUI. We will set CMAKE_INSTALL_PREFIX to the directory similar to the CMAKE_INSTALL_PREFIX as set during the OpenMM installation (e.g., /home/USERNAME/bin/openmm). We will also set the OPENMM_DIR to the directory similar to the CMAKE_INSTALL_PREFIX as set during the installation of OpenMM engine (e.g., /home/USERNAME/bin/openmm). We will set the SEEKR2_BUILD_OPENCL_LIB to OFF. After modifying the variables, we press 'c' to configure. If any issues arise, ccmake will notify us. Once the configuration is successful, we then press 'g' to generate the build files. The ccmake GUI will then close automatically.
