Subject: BUILD: makefile: search for Lua 5.5 as well
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=bfbca23dc2ad1abca4215eb2a39b45f1a86bac7e;p=thirdparty%2Fhaproxy.git

BUILD: makefile: search for Lua 5.5 as well

Support for Lua 5.5 was brought in 3.4-dev2 with commit 1c0f781994
("MINOR: hlua: Add support for lua 5.5") but the Makefile doesn't look
for it, which can be quite confusing on recent distros which start to
ship with it. Let's add it to the looked up names.

 If Lua is not provided on your system, it can be very simply built locally. It
 can be downloaded from https://www.lua.org/, extracted and built, for example :
