Why do I get error messages when compiling a model that contains an S-function block that uses the external S-function module in Real-Time Workshop?

I have a model that contains S-functions.
Under the S-function modules, I have put a library called user32.lib.
When I try to generate code for the GRT target, I receive the following errors:
### Linking ...

LINK : fatal error LNK1181: cannot open input file '\user32.lib'
NMAKE : fatal error U1077: 'link' : return code '0x49d'
Stop.
It seems that the file name "user32.lib" was converted to "\user32.lib" during Real-Time Workshop build process.

This problem results from incorrect usage. The S-Function modules parameter should be used only to list source files. If an S-Function requires a specific library to be linked in, the full path to that library file should be specified via:
Configuration parameters -> Real-Time Workshop -> Custom Code -> Libraries
or by using the rtwmakecfg.m API
Information about using the rtwmakecfg.m API can be found in this URL:
