You have two options.

1. Write a recipe for this package and let OE build it and you can add it to your image with IMAGE_INSTALL if you want it in final image. For OE recipe you can follow devtool workflow to add new recipe or you can manually do it by copying a similar looking recipe and making needed changes.

2. if you dont want to work with OE immediately then you can generate SDK with bitbake -cpopulate_sdk <your image>
install the resulting SDK using the self installer ( .sh file) and then using the SDK, ensure that you use CC, CXX and its ilk
as it is after sourcing the environment.

you might need to do chmod +x for this file. Secondly it might be using wrong ABI  ( hard-float or not ) ensure that
the ABIs of the system and your app are same.

readelf -A <your app>
readelf -A <some app on target>

should be same.
