I would like to specify a relative source code search path using Simulink S-function Builder App, however, there's only absolute path examples given on this documentation page: Build S-Functions Automatically Using S-Function Builder - MATLAB & Simulink (mathworks.com)
How can I specify a search path that's relative to
  • the current Simulink model path?
  • the current Simulink project path?

I think we can set the environment variable in MATLAB and add ENV_PATH to s-function builder to do that.
Use the sfunction builder in the screenshot as the example,
0) set the environment variable in MATLAB command window
>> setenv("PROJROOT", 'path to your project');
1) add a "ENV_PATH" using the dropdown menu of "Insert Path" button which is located in the toolstrip
2) Set the value of new ENV_PATH to "$PROJROOT" in the bottom Libraries table
