set(CPACK_PACKAGE_VENDOR "Redis")
set(CPACK_PACKAGE_DESCRIPTION "\
Hiredis is a minimalistic C client library for the Redis database.

It is minimalistic because it just adds minimal support for the protocol, \
but at the same time it uses a high level printf-alike API in order to make \
it much higher level than otherwise suggested by its minimal code base and the \
lack of explicit bindings for every Redis command.

Apart from supporting sending commands and receiving replies, it comes with a \
reply parser that is decoupled from the I/O layer. It is a stream parser designed \
for easy reusability, which can for instance be used in higher level language bindings \
for efficient reply parsing.

Hiredis only supports the binary-safe Redis protocol, so you can use it with any Redis \
version >= 1.2.0.

The library comes with multiple APIs. There is the synchronous API, the asynchronous API \
and the reply parsing API.")
