Place the `rebuild_file_tables.php` script in a `files` subfolder of the main component.
It requires PHP 7 to run. 

This is what the setup should look like

```
main/files/embed/index.html
main/files/rebuild_file_tables.php
main/CMakeLists.txt
main/main.c
```

Add this to your CMakeLists.txt before `register_component`:

```
#begin staticfiles
#end staticfiles
```

The script will update CMakeLists.txt and generate `files_enum.c` and `files_enum.h` when run.

```
main/files/files_enum.h
main/files/files_enum.c
```

Ensure `files/files_enum.c` is included in the build.

`www_get_static_file()` is implemented as weak to let you provide custom access authentication logic.
