How can I create a new folder under the `src` folder to separately store the `.h` and `.cpp` files?

Hello, I have downloaded your template library. How can I create a new folder under the src folder to separately store the .h and .cpp files? Under the current configuration, this operation fails to compile.

Usually your main cpp file is in ./src and all other headers are in a folder named ./include
