If emacs has support for compilation databases (a 
"compile_commands.json" file), then you can generate one. The easiest 
way to do that is with dev-util/bear:

   $ bear -- make -j16

This will build the project as usual, but a compile_commands.json file 
will be generated in the current directory. Load that file into an 
editor or IDE that supports compilation databases.
