windres

windres may be used to manipulate Windows resources.
windres [ options ] [ input-file ] [ output-file ]
windres reads resources from an input-file and copies them into an output-file. Either file may be in one of three formats:
The exact description of these different formats is available in documentation from Microsoft.
When windres converts from the rc format to the res format, it is acting like the Windows Resource Compiler. When windres converts from the res format to the coff format, it is acting like the Windows CVTRES program.
When windres generates an rc file, the output is similar but not identical to the format expected for the input. When an input rc file refers to an external filename, an output rc file will instead include the file contents.
If the input or output format is not specified, windres will guess based on the file name, or, for the input file, the file contents. A file with an extension of .rc will be treated as an rc file, a file with an extension of .res will be treated as a res file, and a file with an extension of .o or .exe will be treated as a COFF format file.

If no output file is specified, windres will print the resources in rc format to standard output.

The normal use is for you to write an rc file, use windres to convert it to a COFF file, and then link the COFF file into your application.

This will make the resources described in the rc file available to Windows.
