This is a dependency of our upcoming web-based material debugger. This
CL also includes `tnt/CMakeLists.txt`, which builds a static lib in a
minimal configuration that enables WebSocket support. The entire library
is built from only 4 files:
${PUBLIC_HDR_DIR}/CivetServer.h
${PUBLIC_HDR_DIR}/civetweb.h
${SRC_DIR}/civetweb.c
${SRC_DIR}/CivetServer.cpp

### Description
|
|
|
|
The function `mg_cry()` is called when something happens on a connection. The function takes a format string similar to the `printf()` series of functions with parameters and creates a text string which can then be used for logging. The `mg_cry()` function prints the output to the opened error log stream. Log messages can be processed with the `log_message()` callback function specified in the `struct mg_callbacks` structure.
