example doesn't run

[pconrad]

The example:

./run.sh allolib/external/Gamma/examples/effects/vibrato.cpp

does not run under allolib_playground on arm64 architecture. Produces these errors:

Are we building it incorrectly, or is this an example that hasn't been kept up to date with changes in the code?

I updated the Makefiles in the main branch to support arm64 (lanceputnam/Gamma@6ce48be). The allolib fork uses CMake, but I still see Makefile.common (the edited file) in the repo.
