ESP32

[Greg Stewart <gregstewart90@xxxxxxxxx>]

Hello. I am trying to get libssh to work on an ESP32. This is a new
ble+wifi modules with MCU from Espressif. It is gaining popularity, and I
would love to use libssh from the esp32. When I begin, I get this error:

> libssh/include/libssh/libssh.h:67:44: fatal error: sys/select.h

If I comment out that line, the header files are fine. I then try to
compile all of the c files and I get lots of errors. They are found at the
end of the email.

Is there something I need to do to make this work? I've worked with
Espressif too, and they said they have done all they can to help.

Thanks,
Greg
