vcpkg/ports/avro-c/avro.patch
Eric Rosenquist d182f929ee Initial commit of the C API for Apache Avro 
Avro is a data serialization system.

https://avro.apache.org/docs/current/api/c/

A static library is the only build option at the moment.

The patch for PR#217 in the Avro repo is included since it contains a vital memory leak fix that has not yet been merged into the Avro code.
