HawkTracer is a highly portable, low-overhead, configurable profiling tool built in Amazon Video for getting performance metrics from low-end devices.

$ mkdir build       # It'll be different on Windows
$ cmake ..
$ cmake --build .   # This instead of make, so we don't need extra instructions for Windows

Use following interface to define scoped tracepoints:

HT_TP_GLOBAL_SCOPED_INT(int_label);
HT_TP_GLOBAL_SCOPED_STRING("foo");

Use JavaScript comments in your code
