That means the librtalsa.so <http://librtalsa.so/> was not found, which =
could be either because it was never built or
because Csound is not looking in the right place.

Check that your build is actually finding the dependencies and building =
the Csound backend modules (see the messages printed by CMake),
and then make sure that you either install Csound or point your =
OPCODE7DIR64 (doubles) or OPCODE7DIR (floats) environment var to
the plugin directory.
