First add 'mypackageicons.rc' file to the project, this produces 'mypackageicons.res' at compile time (see related SO answer to the question "Including resource file in a project by .RC file rather than .RES file").

Also include {$R mypackageicons.res mypackageicons.dcr} to the component unit (or to the .dpk). This does not produce a '.dcr file', but sets the icon for the component.

Note that my test with a 'BMP' resource failed. I used 'BITMAP' as resource type.
