It's a little more complicated than that, I'm afraid. PrintFunctionNames is
a plugin, so it doesn't get compiled inside clang; you have to pass command
line arguments to clang to tell it where to find the plugin and to load it.
There's a minimal tutorial for how to do something very similar to what you
want here <https://github.com/chisophugis/clang_plugin_example>.

The key thing is the program `invocation_builder.py` which generates
command line arguments that will cause clang to load the plugin. Then you
will just need to add those arguments to CFLAGS or CXXFLAGS in your

Btw if you find anything lacking in that example plugin or not well
explained, please let me know! I'm trying to improve it so that it is as
understandable as possible.
