If I understand you correctly, you have to use some additional library in order to compile RTOS for your system. To do so, you have to add macros to configure.ac to find the library and the header files, and pass that information to Automake. You would then use the information that Autoconf gathered in the file Makefile.am. Note that you have to modify the *am* file and not the *in*, because the latter is the result of Automake operation. There could be cases where it only exists Makefile.in, but I think it¡s not yours. As you say, you'd typically use that libraries in the directory were the library is used. I hope that I haven't missed anything, but I'm sure the rest of the list will complete this information if it were the case.
