Hello, It's somewhat possible. You can compile gem5 as a library (e.g., scons build/<Default build opts>/libgem5-opt.so). However, gem5 *is a python interpreter* and is configured via python scripts. Getting that to work with an external program is "exciting". It's possible to get python working, and there are other workarounds like using the CXXConfig interface, but it's not straightforward or easy to understand.
Unless you're trying to integrate gem5 into another simulator, it's unlikely that invoking gem5 from another program is the best option. Even in this case, I would advise going the other way and using gem5 as the driver simulator. That said, there are many simulators that integrate with gem5. You can easily hook in things like DRAMSim, at one point I integrated it with GPGPU-Sim (this is now incredibly out of date), and there is an SST-gem5 bridge that we are actively working on. Finally, there are many efforts to integrate gem5 with SystemC including implementing the entire SystemC spec in gem5. Hopefully this helps. I'd be happy to provide more specific help with some more information :).
