Yes, but REACTCPP_SO is useless, see below.

And that's perfectly fine. Just let "make install" install header files
and static library. Buildroot will clean them up at the end of the
build, in the "target-finalize" step.

It's much, much better (and future proof) to use the build system of the
package itself when possible, and rely on target-finalize to clean
things up at the end of the build.

Thanks,

Thomas
