# Patch for downstream soname versioning
# Request for this was sent upstream: https://github.com/R4stl1n/cAudio/issues/40
# After a week with no response, I began doing it downstream in accordance with our
# guidelines: https://fedoraproject.org/wiki/Packaging:Guidelines#Downstream_.so_name_versioning
# Accepted upstream! We no longer need this one.
# Patch2:         https://tc01.fedorapeople.org/cAudio/cAudio-downstream-soname-versioning.patch

# We need cmake and a compiler, obviously.
