cmake offers the option to generate a
compilation database in json format
using the option CMAKE_EXPORT_COMPILE_COMMANDS=YES. The database holds
essentially the command, paths and compilers flags used to compile each file of
a project. The generated file (usually called compile_commands.json) can be
used in conjunction with various code completion tools like
YouCompleteMe and Visual Studio’s
IntelliSense
in order to offer more complete information, completion and errors about the
code.
