Subject: Use pkg-config for getting libmemcached CFLAGS/LIBS
X-Git-Tag: v5.2.0~25
X-Git-Url: http://git.indexdata.com/?p=yaz-moved-to-github.git;a=commitdiff_plain;h=94da887fdc444b624e4736e860e9a1777c92e847;ds=sidebyside

Use pkg-config for getting libmemcached CFLAGS/LIBS

Also, require version 1.0 or later of libmemcached.
This is because older versions of libmemcached have
a different API and because we have stability issues
with version 0.31 on CentOS 6.5.
