Presently, if you forget to initialize the git submodules before running cmake, there'll be a helpful message that reminds you to do so. However, on narrow terminals (e.g. 80 wide) there's a word wrap that includes a new line in the middle of the git command, precluding easy copy-paste. This moves the entire git command to its own line to avoid such tragedies. Before: ``` CMake Error at CMakeLists.txt:59 (message): Git submodule externals/inih/inih not found. Please run: git submodule update --init --recursive ``` After: ``` CMake Error at CMakeLists.txt:59 (message): Git submodule externals/inih/inih not found. Please run: git submodule update --init --recursive ```
