Thanks again for this really great project and I'm looking forward to using and adding to it.

I attempted to follow the google docs OVMS developer guide, but I must be missing something.   

The developer guide and the esp-idf instructions seem clear until the esp-idf instructions to run the install.sh script (setting paths, etc),  but this script or similar doesn't exist in the openvehicles esp-idf branch?  And the openvehicles esp-idf is a few months old, many items from the master esp-idf are different now?  does that matter?  

Do the instructions mean to install and set up the espressif's master esp-idf,  and then also clone the openvehicles esp-idf?   Because I think that's what I've done.

I installed the dependencies and espressif's esp-idf, and am able to flash at least hello_world on a regular esp32 board over USB and the serial terminal works with it.  So that seems good.  

When I try to compile OVMS I get errors that look like I'm missing something.  Maybe the something I'm missing is in the openvehicles esp-idf, but my paths are not including it?   Is there a script in the openvehicles esp-idf that I need to run?     Is it ok to have both versions of esp-idf set up at the same time?

First it gives errors about the copyright text to include in the binary?

If I eliminate that error, comment out the lines in argtable3, 

Then I get same & other warnings, and finally a 'No rule to make target'.
