+
+-- Returns a table that contains the Fibre code files and the flags required to
+-- compile and link those files.
+--
+-- args: A dictionary containing the fibre options. Refer to the Compile Options
+--       in README.md for a list of available options. For example the option
+--       `FIBRE_ENABLE_SERVER` maps to the argument `args.enable_server`.
+-- In addition:
+-- args.pkgconf: Controls the use of the pkgconf or pkg-config utility that
+--     shall be used to locate build dependencies. Can be one of the following:
+--        - A string: Use the binary provided by the string. Fail if it doesn't
+--          exist.
+--        - true: Use "pkgconf" and fall back to "pkg-config" if "pkgconf"
+--          doesn't exist. Fail if both don't exist.
+--        - false: Don't use pkg-config. The user is responsible of determining
+--          the required compile and link flags.
+--        - nil: Try both "pkgconf" and "pkg-config". If both don't exist fall
+--          back to a hardcoded list of well-known settings.
+--
+-- Returns: A dictionary with the following items:
+--  code_files: A list of strings that name the C++ code files to be compiled.
+--              The names are relative to package.lua.
+--  include_dirs: A list of directories that must be added to the include path
+--                when compiling the code files. The paths are relative to
+--                package.lua.
+--  cflags: A list of flags that should be passed to the compiler/linker when
+--          compiling and linking the code files.
+--  ldflags: A list of linker flags that should be passed to the linker when
+--           linking the object files.
