Subject: Add --with-luajit configure option
X-Git-Tag: dnsdist-1.0.0-alpha1~248^2~98^2~54^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=refs%2Fpull%2F2338%2Fhead;p=thirdparty%2Fpdns.git

Add --with-luajit configure option

For now we don't do autodetection and you'll need
to explicitly enable it. If it is enabled, we check
for LuaJIT and not for Lua.
