@jamienoss Please take a look when you get a chance.

• Removed everything other than naming from ADD_PLUGIN call.
• Now we fetch and build libuv 1.0.10 from source
• then we import the .so into our project and use that target directly in our add_target_libraries call
• install as file, with correct permissions into lib

@richardkchapman Lorraine informed me that Jamie won't be in for a while to look over this PR. Any suggestions on who else should take a look at it? My first thought would be Ming?

@xwang2713 Please review

HPCC libmemcached.so linked to libmemcached.so.11. Should it need link to libmemcached.so.11.0.0? It does for rpm/deb package install.
Maybe not since we link libmemcached.so.11.0.0 directly

@xwang2713 I just installed the package on centos 6 and it has symlinks for libmemcached.so, libmemcached.so.11, which both point to libmemcached.so.11.0.0 under /opt/HPCCSystems/lib/.

I also checked the plugin and it's linking against libmemcached.so.11 which in turn is actually libmemcached.so.11.0.0 so it looks like everything is good. Is this not how you're seeing it?

[xwang2713]

yes. The code looks good

[Michael-Gardner]

perfect. @richardkchapman should be ready for your eyes
