Subject: [PATCH 2/2] Prefer external miniz library in Sereal::Encoder
|
|
MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

|
This patch checks for presence of miniz library and header file and
|
|
if they are available, they will be used to link to the
|
|
Sereal::Encoder XS module. Otherwise the bundled miniz code will be
|
|
used.
