Rules for creating a new example:

Makefile golden reference for desktop/server example: http-server
Makefile golden reference for the embedded example: stm32/nucleo-f746zg-baremetal
An example must build on Windows, Mac and Ubuntu Linux systems
Assume that user installed tools according to https://mongoose.ws/tutorials/tools/
Makefile must not include any other make files
Use CFLAGS for compilation options
Add CFLAGS_EXTRA to the end of CFLAGS, to allow user to specify extra options, for example:
```
make CFLAGS_EXTRA="-pedantic -O2"
```
If external repository is required, download it on demand using git shallow clone. See embedded example golden reference
Keep Makefile as short as possible, but verbose to understand it easily
Symlink files when required, like mongoose.c, ca.pem, etc. Make no copies
Example's README.md should contain only the title and the link to mongoose.ws tutorial page
