Hi,
You have two main options:
* Use `RccCustomLibs+=/path/to/compiled/library` in a Makefile
* If you need to pick a different library depending on the RCC Platform, you can do `RccCustomLibs_centos7+=/path/to/compiled/centos7/library`
* This variable can be a list of multiple libraries.
* Your Makefile would minimally look like this:
```make
RccCustomLibs_centos7+=/path/to/compiled/centos7/library
```
* `(dynamic/static)prereqlibs`
* If you use this, you need to build your library in the `prerequisites` folder of your project or the OpenCPI repo itself.
* Warning: This is more complicated and error-prone, but more robust when porting to new RCC Platforms.
I'd do the former for a quick solution to get something working but look to move to the latter in the long term.
Cheers,
