How can I include a library (.lib) file in a self written tlc code for a simple s - function ?

I am trying to isolate my entire model consisting of 20 - 30 modules from the individual blocks. If one of the block undergoes a change in Simulink, I have to run the entire code generation process i.e. Generate code (C/C++), compile code (.obj) and then link it to the target hardware. I am trying to avoid this long code generation process by generating a dummy s - function and including a library (.lib file) previously generated during the code generation process in the .tlc file for the s - function. Please let me know how to include libraries in .tlc files !
